Air Pollution and Dust Credited With Weakening Hurricanes Irene and Katrina

By: Jeff Masters 1:30 PM GMT on April 28, 2015

As Hurricane Irene churned northwards out of the Bahamas towards the Northeast U.S. on August 25, 2011, residents there scrambled to prepare for the arrival of what could well be the most destructive hurricane ever to hit the United States. Irene had just devastated the northern Bahamas as a Category 3 storm with 120 mph winds, and the National Hurricane Center forecast called for the hurricane remain at Category 3 strength as it plowed over the Outer Banks of North Carolina. Irene was then expected to slowly weaken to Category 1 strength at landfall on the New York/New Jersey coast three days later. Fortunately, Irene surprised forecasters by weakening unexpectedly to a Category 1 storm at landfall in North Carolina, and further weakening to a strong tropical storm with 70 mph winds when it reached New York City on August 28. Even so, Irene did $16 billion in damage, making it the 7th costliest U.S. hurricane in history, and most expensive hurricane ever to hit the Northeast U.S. (until Hurricane Sandy in 2012.)


Figure 1. Tropical Storm Irene, with top winds of 70 mph, was centered almost directly over New York City in this image taken on August 28, 2011.


Figure 2. The European (ECMWF) model is not known for making good intensity forecasts, and is not one of the intensity models the National Hurricane Center uses to make intensity forecasts. Nevertheless, its 4-day forecast of Hurricane Irene making landfall in Delaware as a borderline Category 3/Category 4 hurricane with a central pressure of 936 mb had forecasters like me sweating a bit.

Why did Irene weaken?
Like most intense hurricanes, Irene underwent an eyewall replacement cycle, a process where the inner eyewall shrinks, becomes unstable, and collapses, and is replaced by a new outer eyewall that forms from an outer spiral band. Typically, this process results in a temporary weakening of the storm of 10 - 30 mph in peak winds and 10 - 20 mb in pressure. After about a day, though, the outer eyewall usually grows more organized and contracts, and the storm re-intensifies. Unexpectedly, Irene never completed its eyewall replacement cycle after it left the Bahamas, and the size of the new outer eyewall grew in parallel with an intensification of the hurricane’s outer rain bands. This resulted in the somewhat unusual case where the minimum pressure occurred 40 hours after the winds peaked in intensity. Research accepted for publication last week in the Journal of Atmospheric Science, led by Barry Lynn of The Hebrew University of Jerusalem, "The sensitivity of Hurricane Irene to aerosols and ocean coupling: simulations with WRF spectral bin microphysics", gives partial credit for Irene’s weakening to dust and air pollution sucked in by the storm. These particles (collectively called aerosols) invigorated the outer spiral bands and outer eyewall, and kept the outer portions of the storm strong at the expense of the inner core. Using a high-resolution model that used a 1-km grid to simulate the storm, the researchers were able to show that dust particles from the Saharan Air Layer (SAL) and air pollution particles from the Eastern U.S. could have caused a weakening of Irene’s winds of 20 - 30 mph, accompanied by an increase of 10 - 15 mb in the central pressure, and caused the observed delay of the storm’s lowest pressure occurring 40 hours after the winds peaked. Unfortunately, none of the hurricane intensity models that NHC uses include aerosol particles, or have the fine 1 km resolution used in the Hurricane Irene study. I hope that within a few years, computers will become powerful enough to run such a model in real time for use in operational forecasting.

How do aerosols weaken a hurricane?
Aerosol particles of the right size and composition (called Cloud Condensation Nuclei, CCN) provide convenient places where water vapor can condense and form cloud droplets. An increase in concentration of small aerosols increases droplet concentration and decreases droplet size. The net effect is a decrease in the collision rate to form large raindrops, and a delay in raindrop formation and rain. As a result, small droplets ascend in cloud updrafts and continue growing by condensation, leading to an increase in supercooled water content. When the moisture condenses in these updrafts, it releases extra "latent heat" (the energy it took to vaporize the water originally, which the water vapor stores). This release of energy leads to an increase in cloud updrafts and an increase in cloud top height and lightning. When this process occurs in the outer bands of a hurricane, the resulting invigoration of the thunderstorms there creates heavy rain that drags down cold air from aloft to the surface, creating pools of cold air near the surface that act to block the inflow of warm, moist air into the hurricane's core, thus weakening the storm.


Figure 3. Dry air/Saharan Air Layer (SAL) maps from the University of Wisconsin - CIMSS (http://tropic.ssec.wisc.edu) for 18 UTC 21 August 2011 (top) and 00 UTC 24 August 2011. Hurricane Irene crossed a wide band of Saharan dust during its northward movement. Figure 3 (top) shows that Saharan Air Layer dust impinged on Irene in three sectors at 18 UTC 21 August 2011. Fifty-four hours later (0000 UTC 24 August 2011) most of the dust was not observable by satellite, but it was still seen to Irene's north in a cloud-free area (Figure 3, bottom). This indicates that the dust seen at the earlier time was likely absorbed into Irene’s circulation.


Figure 4. Official NHC intensity forecasts for Irene every 6 hours from 1200 UTC 23 August to 0600 UTC 28 August. The black line is the observed intensity of Irene. NHC consistently over-predicted the strength of Irene's winds.

Aerosols are also credited with weakening Hurricane Katrina
According to Khain et al. (2010), ”Aerosol Effects on Intensity of Landfalling Hurricanes as Seen from Simulations with the WRF Model with Spectral Bin Microphysics”, ingestion of aerosols also may have been responsible for weakening Hurricane Katrina as it approached landfall in Mississippi on August 29, 2005. Katrina peaked as a monster Category 5 storm with a central pressure of 902 mb and 175 mph winds about 24 hours before landfall, but weakened to a Category 3 storm with 125 mph winds and a 923 mb central pressure when it came ashore. Up to 35 mph of the wind decrease and 15 mb of the pressure rise could have been due to the storm pulling in aerosol pollution and dust particles from Southern U.S. in the final 24 hours before landfall, the authors deduced, using a detailed computer model of the storm.

Why not use aerosols to intentionally weaken hurricanes?
Since we’re pretty sure that aerosols can help weaken hurricanes, why not intentionally introduce small particles into a hurricane to control its intensity? That was the rationale behind a $1 million study by the Department of Homeland Security between 2009 - 2011, HURRMIT (The Identification and Testing of Hurricane Mitigation Hypotheses). Scientists with the project conducted a number of computer simulations on what would happen to a hurricane by intentionally spraying small aerosol particles into the storm using aircraft. They found that in theory this approach would work, with winds decreasing 20 - 30% for Category 4 and weaker hurricanes. However, the hurricanes had to be treated during an intensification phase to get these reductions in intensity; the effect was significantly less when the simulated storm had completed an intensification cycle and was fully mature. In addition, they found that putting too much aerosol into a hurricane’s outer rain bands thrust more water substance into the thunderstorm anvils, lowering storm precipitation efficiency and short-circuiting the reduction in surface winds.

It is quite possible that seeding a hurricane with aerosol particles can actually make the storm more intense, though. The authors of the Hurricane Irene study commented that if aerosols can manage to penetrate directly to the core of a hurricane, they can act to invigorate the inner eyewall and make the storm stronger. In addition, putting aerosols into a tropical depression in its formative phase can help it, since the storm typically needs an extra boost in cloud droplets to get going (however, the dry air that often accompanies aerosols from the Saharan Air Layer often destroys a budding tropical depression.) So, we’d better be really sure we know what we’re doing if we are going to be intentionally messing with hurricanes. I am very sure that we are not really sure, and that we should leave hurricanes alone for the foreseeable future!

I remember Irene well, living in Flushing, Queens in 2011. If my memory serves me correctly, the center passed directly over or just by my house. I remember preparing days in advance for a walloping, stocking up on water and canned goods. Didn't prepare the house physically at all, since we were renting at the time and, frankly, the house was in dire need of repairs.

After Irene came through, I distinctly remember thinking, "Wow, that was nothing. What a wimpy system." I think a twig blew off a tulip tree in our backyard. What a waste.

I saw first hand what Irene did to towns in the Catskill Mountains in upstate NY. Prattsville in particular (and pretty much any town along the Schoharie River) was devastated. Homes are still condemned and sitting destroyed on their foundations since the last time I visited, which was summer 2014. Sad sight.

The relative puny impact of Irene directly affected how I prepared for Sandy in 2012, severely underestimating the power and scope of the storm. I've learned my lesson and wont make the same mistake twice, especially since the Oct 2012 superstorm was the catalyst for hanging out at WU far more often.

Gulf water vapor.. You can see the system visibly drying up, just disappearing into thin air.. I don't really see to much dry air around other than to the south, but in the last few frames it looks like its starting to get behind the system a bit, almost sandwiching it.

EDIT: you can also see it being pushed along by a front on the north-west, which is effectively slowly sheering the system away into nothing.
Good morning everyone I am posting today something not of weather science but of Earth Science. I have a graphic that depicts a rise or uptick in seismic activity over the last 50 years or so. There is an argument going on in the earth scientific world about magnetic polar reversal or just the ebb and flows of natural earthquake and volcanic activity. Since the 2004 Indonesian EQ which was a 9.2mag. There has been an increase in frequency and intensity of EQs and volcanos. I am not on either side of the argument that are posed by earth scientist at this time because I don't have the knowledge or experience to formulate a theory about it. I do know this whether it is climate change affecting tectonics, natural cycles, or magnetic polar reversals, we need to be vigilant about what is going on.

Looks ESE to me.....
Thanks Dr. Interesting study but it seems to me that there is a thin line between aerosols and the normal dust particles generated by SAL regardless of the results of this modelling study. I always assumed that Katrina, thankfully, weakened before landfall due to some shear issues, dry air intrusion, and issues we often discuss here, with shallower waters and the slight cooling off of SST's due to coastal upwelling as many storms have approached the Northern Gulf coast. I am (personal opinion) not sold on the suggestion that the aerosol issue was as significant a weakening factor as the SAL and upwelling issue related to Katrina.


Bad day to be on the beach.

I was thinking more to the line of ENE, but I don't know.

In any case, FL is gonna get some much needed rain, and this thing is moving along rather nicely.. it shouldn't be here TOO much longer. In fact, it looks like it should be almost gone by tomorrow evening.

Could introducing aerosols into the atmosphere cause unintended negative effects to humans and animals over the long term? Also I remember being told years ago that aerosols increased the green house effect. The reason I remember it is because I stopped using aerosol hairspray and switched to pump hairspray, Has new research changed that?

If this is a dumb question I apologize.
A better study perhaps on the aerosol/pollution issue might be on Western Pacific storms on their approach to Asia; lots of pollutants in the air from manufacturing concerns in China, etc. The flip side is that storms/typhoons starting to reach China and Japan also tend to weaken due to cooler sst's as they move towards the Northern latitudes as well.

Pole reversals? No. From Magnetic Pole Reversal Happens All The (Geologic) Time: "Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north with a magnetic compass in your hand, the needle would point to 'south.' This is because a magnetic compass is calibrated based on Earth's poles. The N-S markings of a compass would be 180 degrees wrong if the polarity of today's magnetic field were reversed. Many doomsday theorists have tried to take this natural geological occurrence and suggest it could lead to Earth's destruction. But would there be any dramatic effects? The answer, from the geologic and fossil records we have from hundreds of past magnetic polarity reversals, seems to be 'no.'"

Now, your link states, "Out of the 17 strongest earthquakes above 8.5 magnitude on Richter scale during last 110 years, the 6 strongest earthquakes (above 8.5) happened during last 11 years." That is, of course, completely untrue. Of the 17 largest earthquakes over the past 110 years, just five have occurred in the past 11 years. The remaining 12 quakes on the list--including the first, second, and fifth largest--took place decades ago.

Out of curiosity, what type of vigilance do you propose to prepare for climate change affecting plate tectonics (something that occurs over tens of millions of years, if at all) or magnetic polar reversals? Is there something I should be doing to my house to prepare for this? Will boarding up my windows help? Stock up on canned food? Fill my bathtub?

I suspect that if you look at numbers of earthquakes, that statistic is bloated by the (recently admitted) effect of fracking and waste-disposal wells in a number of areas. I personally doubt much effect on intensity or frequency from either climate change or Earth magnetic field reversal. There is a possibility of increased volcanic activity resulting from earthquakes near a volcano but the correlation is not clear or proven as far as I know.

OMG so that's how rain looks like!
I suppose you could claim that air pollution played a role, but Irene's large COC, slow movement & track rather close to the US, allowing sinking & low theta-e air off the surrounding continent to be attained through the low-level inflow & to be entrained into the circulation, historically speaking, have been factors that weaken "slot" hurricanes like Irene that try to strike the eastern seaboard from broad recurvatures. The vast majority of full-blown major hurricane strikes from ~30N on northward along the eastern seaboard, have primarily came from storms that came in relatively perpendicular to the coastline, thus limiting the amount of indirect interaction to land (among other things) before their actual landfall...









Helene was "close enough" passing within 10 miles of southeastern NC as a category 4 hurricane.

Local news just showed a video sent in from a viewer of the hail earlier in Rotunda. The hail was pretty decent size (looked like nickle sized hail or so).

In over 20 years it has only hailed one time (about pea sized) here at my location in Fort Myers.
Coming from previously living in Oklahoma and Texas, that's pretty incredible to me (to go over 20 years and only see it hail one time, especially with all the thunderstorms we get here in the summer).
I will have a blog later for the possible subtropical development next week.
Somebody needs to lower the force field in Ft. Myers! Rain seems to evaporate as it approaches that area. Shees!



Think the NWS in Melbourne might want to rethink the rain chances here on the Space Coast. All the rain is going to miss us.
If this verifies then this WWB in about a week or so will seal the deal for a Strong El-Nino come June or July as there is a very significant WWB on the way around May 5th.

Hey. What could possibly go wrong ???

On another point the blog mentions introducing aerosol data into hurricane models and running much higher resolution hurricane models and then proceeds to state that we are waiting for the increased computer power
of the near future to be able to run them. This is true but the other question, why not begin using aerosol data
in the model, was not answered. It may be another computer cost issue; to do it right requires fine scale microphysics rather than the parameterizations used at coarser scales. BUt the blog entry didn't say and I think this answer is known to our science now. So this enquiring mind wants to also know.
Yet ANOTHER non rain event here in Sanford, Florida!! Its getting frustrating seeing all the heavy rains either to the north or to the south time after time
Interesting article. Your comments regarding the effects of cloud seeding on the core and outer bands suggest that the appropriate approach to reduce the intensity of a hurricane should be two pronged. First, as the hurricane nears maximum intensity, seed directly into the inner core. The resulting intensification will collide with physics and, I would predict, result in inner eyewall destruction. Presumable this would drop the overall intensity and result in the hurricane beginning a new intensification/eyewall replacement cycle. They, based on the suggested ability of seeding to inhibit intensification, now would be the appropriate time to seed the outer bands to disrupt the intensification process.
Almost down to the Keys now; it really moved quickly from the Northern Gulf towards South Florida leaving other parts of the State in a drier slot today than anticipated yesterday:

The 2015 hurricane season analogs I compiled ~4-5 weeks ago appear to be doing a fine job capturing the US temp evolution & distribution since the end of last winter...



Based on these analogs, it appears summer will get off to a fast start over the east-central US in May & possibly even June, however given the amount of water that's being put into the ground, particularly over the central US & Texas, the +PMM, & background +PDO/ENSO state, we may see a substantial cut-down in the heat during the heart of summer over the center of the nation... I certainly wouldn't mind to see a nice growing season attempt to slash the price of corn...

Quoting 18. WeatherConvoy:

Good morning everyone I am posting today something not of weather science but of Earth Science. I have a graphic that depicts a rise or uptick in seismic activity over the last 50 years or so. There is an argument going on in the earth scientific world about magnetic polar reversal or just the ebb and flows of natural earthquake and volcanic activity. Since the 2004 Indonesian EQ which was a 9.2mag. There has been an increase in frequency and intensity of EQs and volcanos. I am not on either side of the argument that are posed by earth scientist at this time because I don't have the knowledge or experience to formulate a theory about it. I do know this whether it is climate change affecting tectonics, natural cycles, or magnetic polar reversals, we need to be vigilant about what is going on.


More Fatal Earthquakes to Come, Warn Climate Change Scientists


“There’s a volcano in Alaska, Pavlov, that only erupts during the autumn and winter. The 10cm or 15cm rise in sea level during the winter months, when low pressure comes over, is enough to bend the crust and squeeze magma out. That’s an example of how tiny a change you need,” he said.

Meanwhile, geologists modelling the effect of retreating ice sheets in the northern hemisphere predict more volcanic activity as pressure is released on fault lines. McGuire points to three eruptions in five years in Iceland – “You can’t say that’s statistical proof but … it makes you think.” ………………………………………..Som e of McGuire‘s colleagues believe he overstates the earthquake risk of sea-level rise and changing rainfall. There is just not enough data yet to prove the hypothesis, says Professor Burgmann. But he is convinced Maguire is right when he talks about volcanic eruptions.

“Ice unloading at the end of the ice ages produced a flurry of volcanic eruptions. That makes sense to me – it’s very true that if you take pressure off a magmatic system that can activate eruptions. There’s solid evidence of that in Iceland.”

NEW YORK (Reuters) – Warning of an “innovation deficit,” scientists at the Massachusetts Institute of Technology say declining government spending on basic research is holding back potentially life-saving advances in 15 fields, from robotics and fusion energy to Alzheimer’s disease and agriculture.

Science funding is “the lowest it has been since the Second World War as a fraction of the federal budget,” said MIT physicist Marc Kastner, who led the committee that wrote “The Future Postponed” report, issued on Monday. “This really threatens America’s future.”

The report lands at a time when federal spending on research has become unusually politicized.

Cuts mandated by the White House’s and Congress’s failure to reach agreement on reducing the federal deficit have chipped away at the budgets of the National Institutes of Health and other science agencies; legislation on research spending is tied up in debates over, among other things, climate change.

Federal spending on research as a share of total government outlays has fallen from nearly 10 percent in 1968, during the space program, to 3 percent in 2015. As a share of gross domestic product, it has dropped from 0.6 percent in 1976 to just under 0.4 percent.

The pullback comes as other countries are increasing science spending, scoring achievements that leave the U.S. in the dust. The European Space Agency landed the first spacecraft on a comet, and China developed the world’s fastest supercomputer, both in 2014.

Actually I think high res models like the HRR predicted this individual thunderstorm complex very well. The problem is the global models have suffered very much from placement and development of the surface low, as well as timing and placement of over upper disturbances.

The reason why you're area might not get as much rain as earlier anticipated is that it seems the models generated additional vigorous disturbances out of nothing through tomorrow. That is the original model consensus was to have 2 more major thunderstorm complexes move through while the upper trough and frontal system are still to the west.

If you read the NWS discussion out of both Tallahassee and Ruskin, they discuss how the models handled the evolution of the upper features very poorly.
With that said, there still will be additional chances of rain through Wednesday night into Thursday morning, but it's not looking like there will be 2 more large thunderstorm complex events in addition to the one this morning like the models were showing before.

That's why rain chances dropped this evening and tomorrow from 80% to 50-60%.
Kinda sucks but it seems models often screw up when weather systems begin to impact Florida. Seems the NWS offices down here have to use the complex scenario with model inconsistency and uncertainty wording more often.

Be glad you are getting some heavy still, models had 100% rain chances and 1-2 inch QPF for us yesterday, so far we haven't had anything in the entire viewing area except 0.01-0.05 from some slight rain for a couple hours yesterday.

Well, the 12Z GFS seems to agree with you that we won't be getting much more rain. I knew this would happen because I took some water out of my pool last night anticipating 3 inches or so. Every time I proactively do that, we get much less. Go figure.

MID 70S AND MODERATE INSTABILITY IS PRESENT WITH MLCAPE ESTIMATED IN
THE 1500 TO 2500 J/KG RANGE. THE WSR-88D VWP AT MIAMI SHOWS
UNIDIRECTIONAL WINDS FROM JUST ABOVE THE SFC TO MID-LEVELS WITH SOME
SPEED SHEAR ABOVE 4 KM AGL. THIS IS CREATING 0-6 KM SHEAR NEAR 55 KT
WHICH SHOULD SUPPORT STORM ORGANIZATION AND CELL ROTATION WITH THE
STRONGER AND MORE PERSISTENT STORMS. ALTHOUGH SUPERCELLS AND HAIL
WILL BE POSSIBLE WITH CELLS THAT CAN REMAIN SEMI-DISCRETE...THE
TENDENCY MAY BE FOR STORMS TO DEVELOP INTO BOWING LINE SEGMENTS.
THIS WOULD FAVOR A WIND DAMAGE THREAT ESPECIALLY AS SFC TEMPS

Even this current GFS precip outlook is strange, notice the odd dry slot over land in Central Florida sandwiched by a sudden gradient of heavy rain on either ocean area? That doesn't even physically make sense.

Just another sign the models aren't handling this system well. I'd say there's a decent shot you'll get some additional showers before the whole system clear,s but probably not anything too heavy.

As for my area, tough to say if we'll even get anything. We should get some rain if the surface low actually gets more organized and moves just to our north, but if the low moves to our south, we probably won't get anything.

Models are keying in on another system this time a hybrid maybe sub tropical very close to E C FL early next week. If that were to occur then you will most certainly see this GFS precip map not verify as heavy rains would be focused across NE FL from Cape Canaveral up to Jacksonville.

Sadly its how the pendulum has swung during the recent generation as to human thinking, to use nature to make the quick profit.

There will always be countries or better stated "leaders" that will take the easy way to try and get a leg up on what they perceive is their "enemy" or competitor.

There are (is) ways to influence nature without causing unknown** outputs/results and ways cause this influence with little or no side affects**. Goodness knows i tried to share some, had no luck, just finishing flushing boxes of pgs/my theories down the terlet, lots of paper in 5 gallon buckets gets real sticky becomes paste like been plunging globs of paper down terlut over last few weeks ...oops TMI.

In this manner one is not changing the weather (forcing nature is not good) one is allowing what nature will create to form but either steering natures creations or harnessing it for power as my "Tabasco turbine Islands" dream that would bring economic stability to Louisiana and allow for power from steered TS/hurricanes to be sent via  massive turbines on parishes (clean not outing anything just taking in steered wind-streams) to all continuous states (even Canada, Caribbean) states (will never happen in my lifetime... if i may compare it to another "dream" that was impossible but done,  it was to build an unbuildable dam, the Hoover Dam, sadly many died and in return less than 100 yrs later we show disrespect to so many that sacrificed to build the impossible (be it The Hoover Dam or Mercury test flights)  by cutting short the programs that help nourish the imaginations and build those ideas that lead to major discoveries that help all people.

Another idea i posted (also removed from my blog by me...though on the Dr.'s board it was removed (was also banned for some hours/day ) cause i had added too much of my weird science theories...i guess...though i mean well) was an idea i wanted to put out there again s to the use of balloons to lower CO2 by filling them with certain chemicals that neutralize CO2's ability to build up in the Atmosphere(s) and these chemicals would not create a worse (side)affect. As balloons would be created to pop at certain atmospheric heights/pressure or by remote and there content help break up CO2.

Again the desire to "control" nature will happen, heck  its been happening since man began to think independently.
Remember Grothar, **play that background going into a memory music**  when you busted that tablet on the Mount cause you invented the shirt pocket and wanted to fit the tablet into that pocket? 
We see it  through medicine or other sciences, so why not do it WITH weather and by using means that have the least side affects.
In ancient times it was done with teas, herbal remedies by testing every plant man came across as people died or became healthy those experiences where passed on but when modern science connected itself to placing profits ahead of knowledge, as in pharmaceutical companies paying to destroy many plants so they could create a similar ARTIFICIAL versions/"cures" instead of using thousands of years of knowledge, we lost lots of knowledge. In the end those companies made less money and we ended up with more unknown side effects. Its not that everything natural is better, its that knowledge is better and by learning and listening to people experiences we all learn how to benefit from every millimeter of nature, in return  nature benefits and mankind benefits.


**FOR INSTANCE, If we learn how to influence Tornadoes as in steering a Tornado and / or causing them to  "hop", then one can create areas near major towns  where tornadoes can be safely turned towards e.g. a Tornado graveyard if i my use those words and still have nature form tornadoes as a way of balancing "the books" as to Earth's equilibrium but do it in a manner where the least amount of people suffer, people will still have to take shelter but if 8 of 10 times the Tornado is steered to avoid damaging homes, people will still have nerves rattled but have homes/communities their personally treasured belonging to go back to.....win-win

but i digress, i just heard my toaster oven bell ring ...my upside down mac n cheese sweet potato veggie pizza supreme is done...yup i'm on a diet have to watch my gurrrly figure ...all 5 of them.

There's no discrepancy here. Global warming is the observed increase in average global temperatures. This in turn affects global weather and climate patterns.

So what are you saying it is good and bad?


Neither and both. Climate change results in many different aspects being affected. Some of them are helpful, some of them are not. The overall balance however is detrimental; we depend on a stable climate. We've built our infrastructure around a stable climate. Any change in climate will lead to problems.

100% garbage. There's multiple science organization across the world that track weather and climate data, so if you don't believe US sources you can find them elsewhere. But if you're a nutter and believe that there is some sort of global conspiracy that's been happening since the 1800's, then there's really no point in discussing it further.

CA draught is because rain cycle is in that stage and if the dumb leaders in CA would not dumb water in ocean would not be so bad. Sound look at what AZ does with rain and snow very little goes down the Salt River, but in LA billions of gal go down the LA River


English must not be your primary language. Even so, the gist of what you said, again, makes no sense. The drought is caused by the persistent decrease precipitation as a result of shifts in dominant patterns over the region that has been going on for a while now.

And no, billions of gallons are not going down the LA river. It's not even a river, and hasn't been for a long long time. Here's a random picture.

At 2:00 PM WST, Tropical Cyclone Quang, Category Two (991 hPa) located at 15.5S 109.1E or 890 km northwest of Exmouth has 10 minute sustained winds of 50 knots with gusts of 70 knots. The cyclone is reported as moving southwest at 6 knots.

Storm Force Winds
=================
25 NM from the center in northeastern quadrant
25 NM from the center in southeastern quadrant
25 NM from the center in southwestern quadrant
25 NM from the center in northwestern quadrant

Gale Force Winds
===============
60 NM from the center in northeastern quadrant
80 NM from the center in southeastern quadrant
80 NM from the center in southwestern quadrant
60 NM from the center in northwestern quadrant

Dvorak Intensity: T3.5/3.5/D1.5/24 HRS

Quang is expected to continue developing as is moves south overnight and then to the southeast tomorrow. The cyclone is then expected to weaken as it moves closer to the far northwest of the state on Friday

Forecast and Intensity
===================
12 HRS 16.5S 108.8E - 60 knots (CAT 2)
24 HRS 17.7S 109.2E - 70 knots (CAT 3)
48 HRS 19.8S 110.9E - 50 knots (CAT 2)
72 HRS 22.3S 112.5E - 30 knots (TROPICAL LOW)

Additional Information
=======================
Satellite [visible and microwave] imagery is showing improved curvature and wrap around the system. Dvorak analysis gives a well defined curved band pattern of 0.8 wrap and an FT/CI of 3.5. The analyzed intensity of 50 knots is also consistent with ASCAT, though objective guidance [ADT/SATCON] is slightly lower. Imagery and ASCAT show a compact circulation and the contraction of gales on the southeast quadrant evident from the past 36 hours.

The broadscale environment is favorable for further development in the next 12-24 hours - wind shear being low, strong upper level outflow and sea surface temperatures above 29C. Thus intensification to category 3 intensity [65-70 knots] is forecast for the next 24 hours.

However, dry air that is currently evident on the western periphery is expected to combine with increasing wind shear from late Thursday and particularly during Friday resulting in rapid weakening below cyclone intensity prior to landfall. Nevertheless gales may persist in the southeast quadrant and hence there remains the possibility of gales or near gale-force winds about the northwest of the state late Friday and into Saturday morning.

The track is likely to shift to the south overnight and then towards the southeast during Thursday as the dominant steering ridge shifts more to the east of the system ahead of a broad mid-latitude trough in the Indian Ocean.

Model guidance still has a reasonable spread of possible tracks and intensities. Models taking the system east of the forecast track are stronger [relative to the other models], while models west of the forecast track have the weaker systems. This is consistent with the shear being weaker in the east and strong in the west.


The dry air is coming :)
Good Morning...

In a weeks time heights across FL and adjacent ATL coastal waters should start falling as a low attempts to develop.

I believe GFS at this time is being a bit too enthusiastic about it, while ECMWF keeps it as a general broad area of low weak pressure. Time will tell... here's a 500MB height comparison between GFS/ECMWF @ 168HR



Green = GFS ; Cyan = ECMWF

I received 0.87" yesterday and nothing so far today. The disturbance that rode into S FL overnight narrowly missed bringing the Tampa Bay area some more rain. My father lives in Boca Raton and he said it rained heavily all night and this morning, complete with thunder. That is really great that S FL got some decent rain. The models missed the mark on C FL, as they were showing 2-3" of rain, but 0.87" is beneficial nonetheless.

4" to 5.50" seems to be the norm across E C FL for April it seems. Average is just 2.42" so we are well above that. Also models are showing what could be a interesting set up for Eastern FL early next week. Could be some very heavy rain across coastal areas.

And no, billions of gallons are not going down the LA river. It's not even a river, and hasn't been for a long long time. Here's a random picture.



The LA river is more like a creek.


A little simple math shows that the Mississippi river discharges approximately 383.3 billion gallons of water daily at its mouth (assuming average flow rate - 593,000 cubic feet per second and the mouth is considered to be Baton Rouge).

By comparison, the LA river discharge 1.46 million gallons of water daily at its mouth (assuming average flow rate - 226 cubic feet per second and the mouth is considered to be Los Angeles Harbor).

That means (assuming average flow rates), it takes the LA River 718 years to discharge the same amount of water that the Mississippi River discharges in one day.

Flood rates and low flow rates are different, but the maximum recorded flow rate at the mouth of the LA River was 129,000 cubic feet per second, or roughly 22% of average flow of the Mississippi.

For comparison, 129,000 cubic feet is the same size as a cube slightly smaller than 51 feet on each side.

Concerning the California drought....It puzzles me that they are going to build some train tracks for a cost of near 100 billion dollars....it would seem the money would be better spent with building desal plants to help with the drought...With the state far from a budget surplus priorities seem messed up....
They've also talked about oil slicks inhibiting the intensification of tropical storms. Probably not a good idea to mess with mother nature. Hate to be the ones responsible for adversely altering the outcome of a hurricane because of some theory that didn't pan out.

i think you first have to look at where that money is coming from and could it be used a dsal plants if not used for rail....second you have to look at california's water usage and then realize that of water used in california...50 percent is for enviromental uses....40 percent is used for agriculture....and 10 percent for urban use....desalination is not going to have a significant impact on the agriculture use....

And Key West doesn't have a typical Florida wet season like the Florida peninsula, because it doesn't have the East Coast/West Coast sea breeze interactions.

Key West depends on Tropical Storms during the late season in August and September for a lot of its rainfall.
(only 46" annually - considerably less than most of Fl.)

Example - Key West averages only 5.16" in June and 4.12" in July.

Here in Fort Myers we average 10.09" in June and 9.04" in July.
We have a much more dramatic wet season because once the S.E. flow sets up across southern Florida, it interacts with our West Coast sea breeze and produces rain pretty much everyday.

Here is the link to the Cimss site; you will have to do some searching to see how far back they archive the SAL plots (as noted from Dr. Masters) in terms of his example from 2011. BTW, here are the current levels as of today. Interesting to note how the SAL is a mid-level feature when you compare the available water vapor in the upper levels at the moment.

I think a weaker more broad solution on the Euro seems more likely. GFS does have a tendency to develop systems out of nothing due to convective feedback and this appears to be the case again.

Case in point below notice the upper level low off SW FL or over SW FL then well off to the NE is where the GFS spins up a low.

Quoting LargoFl:
may 6th, a lot of models have something out there............................................. ...


If the GFS verifies, it keeps the low offshore basically stationary for Wednesday - Saturday. If that happens, it will keep the weather dry for most of Florida by turning the wind out of the north. (strong lows off Florida's East Coast usually give the Peninsula dry weather).

But if the low forms closer to the coast and remains there while it stalls out, then the East Coast of Florida could see some significant rainfall.

WPC siding with the more sensible Euro. Weaker/broad. Clearly a case of convective feedback on the GFS and the CMC well we know the case about that.

No rain across the state because of the counter clockwise flow around the low. But this will all depend on the strength and position of the low (which is subject to change).


Tampa Bay area - looks like great weather for the next 4 days.
Forecast is to become a category 4 tropical cyclone in the next advisory!!!

A Haunting Timelapse Video Shows Arctic Sea Ice Slowly Slip Away

A warning: The video you're about to watch is heartbreaking. In just a few seconds, you'll see 27 years of Arctic sea ice melt like a handful of snowflakes next to a space heater.





Haunting 5 minute video ad with a lot of nearly-naked women in a spa, but the 1 minute Arctic ice video did not play in 2 tries. Disappointing performance, Slate.

this site is really broken
A Vancouver-based company has announced that it’s teaming up with NASA to help send out live, high definition video of the Earth taken from the International Space Station.

Scott Larson, the CEO of UrtheCast Corp., says within a few months his firm’s website will be distributing the real-time video taken by four cameras located on a European Space Agency module on the space station. The cameras have been operating for almost a year.

Larson says UrtheCast will be tapping into a view of the world which he describes as breathtaking and inspiring.

UrtheCast has already built and installed its own two cameras – a still camera and a high-definition video camera – on the Russian section of the space station.

The still camera is already in operation and the full-colour video camera is expected to begin streaming this summer, once tests are completed.

The company’s two cameras can monitor the environment, humanitarian relief, agricultural land, and even social events on the ground.

UrtheCast has already announced that it will be sending another video camera and a radar sensor up to the orbiting space laboratory in 2017.

Audi has successfully made diesel from air and water is one of the "infotaining" headlines in cmmnt#373 of BB latest news.
(actually began 2+ yrs ago, the media went nuts when the minister used it, WHOA! so its become "new" news.)

Remember to nature its either sugar or salt. In this case a form of sugar so in the end its still being released into the atmosphere and becomes CO2 BUT cause humans are using up some of the CO2 they are harvesting from the atmosphere in the end 3 parts of CO2 become only 2 parts, so less CO2 is good news???...lets hope these companies are not burning too much fossil fuel to recover the CO2 from that burning THEN planting trees and getting in the end a "green engine" grade 'cause of the planting of trees is to offset the more burning of fuels needed to recover CO2 from the burning fuels exhaust one can call that loop hole "catch CO22" OH GAWD i'm turning into "sar2401b" (wait that's a good thing)

...NEXT...

My unproven 22cents::

AGAIN Good news if REALLY, LESS CO2 is the END (pun intended) result BUT now science will learn its not just that the "old" mostly carbon based Diesel Fuels that is what elevated disease risk but that higher revving engines that also cause / attract more opportunity for the human body's "energy windows" some call chakras, others call the " 7 sealed books", i call them "glandular intake via grounded sounds openings" to attract negative/chaotic energies which raise the opportunity for diseases. Which is why i state electrical hum leads to diseases, not how close one lives to power plants (not good but not the main negative) but the angle from several electrical plants (even for miles) joins up / is focused onto ones home/body and why the energy i spoke of is disease free energy as it taps into the science of Galacsics which is grounded to the ethereal world (universe) not toward a solid, as physically grounded energies are.

Why is that a big deal?

When energy is grounded to a solid its "kick back" (as sound..hum) enters your 3 tiered complex body (self-spirit-soul) when energy is grounded via an ethereal method its goes into space where "gawd" (really the ultimate in all sciences working together, not an old bearded man) recycles it and you get much less kick back, but i'm nuts lets see if in 10 yrs after these engines are in mass production and science will scratch their skulls and wonder why are diesel drivers still be suffering from more disease than drivers using other engines when they thought replacing the diesel fuel with a cleaner fuel would solve not just air pollutants but the connection of diseases to drivers that used old diesel engines.

When one meditates, ones own ohmmmmm (energy) is generated via an etherealy ground body (your spirit-soul connection so you can leave your body via meditation / deep prayer) NOW that's real efficient energy
...unless you pass gas as yer meditating COpew

yoboi quick turn on the 30,000 BTU AC on HIGH.

Satellite data disagrees, there is a new version of UAH (6.0) and it shows no significant warming. So now we have two temperature data sets (RSS and UAH) showing no significant warming.

Here is a link
Here is a graph of the new data set
So Spencer and Christy have adjusted the UAH satellite data downward yet again? They last did that just about two-and-a-half years ago. Can't wait to run the new numbers through the graphinator next week. Only problem is, it's still going to show a fast rate of warming, meaning that Spencer/Christy will likely have to yet again "adjust" the numbers from 1990 forward...

California Gov. Jerry Brown Orders Aggressive Greenhouse Gas Cuts By 2030
Posted: 04/29/2015 11:39 am EDT Updated: 39 minutes ago


California Gov. Jerry Brown issued an executive order Wednesday directing the state to cut is greenhouse gas emissions 40 percent below 1990 levels by 2030, the toughest proposed cuts of any state in the nation.

The 2030 target will ensure that California can meet its emissions target for the middle of this century, which calls for an 80 percent cut by 2050, Brown said. The state is already on pace to meet its goal of bringing heat-trapping emissions down to 1990 levels by 2020, a target set under a 2006 state law.

"With this order, California sets a very high bar for itself and other states and nations, but it's one that must be reached -- for this generation and generations to come," said Brown in a statement Wednesday morning.

Brown noted that the target puts California in line with the European Union, which has also committed to a 40 percent reduction by 2030.

The governor's office also said the target would put the state on track to reduce its own emissions to the level that nations around the world will need to meet to limit global warming below 2 degrees Celsius, "the warming threshold at which scientists say there will likely be major climate disruptions such as super droughts and rising sea levels."

The cuts are more aggressive than the federal targets that the Obama administration has outlined, which call for reducing emissions 26 to 28 percent below 2005 levels by 2025. (Emissions levels were lower in 1990 than in 2005.)

Brown's executive order identified specific climate impacts to California, noting that the state is already seeing "loss of snowpack, drought, sea level rise, more frequent and intense wildfires, heat waves, more severe smog, and harm to natural and working lands."

"Governor Brown’s announcement demonstrates that California leaders can continue to set the pace for the rest of the world when it comes to tackling the urgent climate crisis and stepping up efforts to adapt to its already-harmful effects,” said Lauren Faber, West Coast political director at the Environmental Defense Fund, in a statement.
