U.S. gets unusually boring January weather; Thursday storm to ease Midwest drought

After an unusually intense period of extreme weather during 2011 and 2012, the U.S. had its quietest month in nearly two years during January 2013, according to NOAA's U.S. Climate Extremes Index (CEI). The index tracks the percentage area of the contiguous U.S. experiencing top-10% and bottom-10% extremes in temperature, precipitation, and drought. The CEI during January 2013 was 14%, which was the lowest since the 12% value during February 2011. On average, about 20% of the contiguous U.S. experiences top-10% extreme weather as defined by the CEI. In 2012, just two months (October and February) had below-average CEI, so the weather of January 2013 was a welcome relief from our recent "new normal" of increased extreme weather. Of course, the month wasn't completely without notable weather--the tornado outbreak of January 29 - 30 generated 57 tornadoes, the second largest January tornado outbreak on record. January 2013 ranked as the 39th warmest January since 1895, said NOAA's National Climatic Data Center (NCDC) in their latest State of the Climate report. Utah and Nevada had a top-ten coldest January; no states had a top-ten warmest January. The January warmth was enough to make the 12-month period ending in January 2013 the warmest such period for the contiguous U.S., with every state being warmer than average. Sixteen states, across the central U.S. and Northeast, were record warm, and 27 additional states were top ten warm.

Drought conditions improve slightly; wetter weather on the way to Midwest drought region
January 2013 had slightly above-average precipitation over the contiguous U.S., but there were notable wet and dry extremes. Louisiana had its wettest January on record, and Michigan, Virginia, Tennessee, and Mississippi all had top-ten wettest January weather. Florida, California, and Connecticut all had top-ten driest January weather. Heavy rains in Alabama and Georgia helped give that region no areas of exceptional drought for the first time since January 10, 2012. However, the core of the drought area over the Midwest U.S. shrank only slightly, with the area of the contiguous U.S. experiencing moderate-to-exceptional drought going from 61% on January 1 to 56% on February 12. The U.S. Seasonal Drought Outlook, issued February 7, calls for new areas of drought to develop over Florida, Texas, and California. However, some improvement in drought conditions is expected over about 40% of the drought region by April 30. The latest forecasts from the GFS and European (ECMWF) model show a modest shift in the jet stream pattern during the remainder of February, which may allow more moisture-bearing low pressure systems to pass through the main portion of the Midwest drought region. One storm for sure will arrive on Thursday, and many areas of the drought region should enjoy their their wettest day in months.

Forward on Climate rally on February 17th in Washington, D.C. 
On Sunday, February 17, at noon EST, what is expected to be the largest climate rally in history will take place in Washington D.C. The rally is a project of the Sierra Club, 350.org, and the Hip Hop Caucus. The organizers mustered 15,000 protesters last year in D.C. to protest the potential approval of the Keystone XL Pipeline (meant to bring oil from Canada's tar sands into the U.S.) Protesting the potential approval of the pipeline will be a major focus of Sunday's rally, as well. More broadly, the rally aims to put pressure on President Obama to make good on the promises he made during Tuesday's State of the Union Address:

"But for the sake of our children and our future, we must do more to combat climate change. Yes, it’s true that no single event makes a trend. But the fact is, the 12 hottest years on record have all come in the last 15. Heat waves, droughts, wildfires, floods – all are now more frequent and more intense. We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science – and act before it’s too late….But if Congress won’t act soon to protect future generations, I will."

It's about time that the President began talking about the reality of our changing climate, and the need to pursue aggressive actions to combat human-caused climate change. January 2013 was a welcome relief from the intense stretch of extreme weather our nation has suffered over the past two years. But the extreme weather of 2011 - 2012 is going to be more typical of our "new normal" of weather during the coming decades. Earth's climate is warming, and the overwhelming majority of climate scientists agree that human activity is the main cause. Extreme weather events are increasing in response to the warming climate. People can take cost-effective actions to limit the damage, and our lawmakers are going to come under increasing pressure from grass-roots efforts like the Forward on Climate rally to act to slow down climate change.

I'll have a new post on Tuesday.

The Northeast is very fortunate Winter Storm Plato is tracking farther east. It's of equal intensity to Nemo and would have been a significant blizzard if it would have tracked closer to the coast.

Wow, out of nowhere we just had an M class solar flare, the first in over a month! The odds of an M flare today were estimated to be just 1%. The source appears to be an extremely rapidly growing region in the NE region of the Sun, rotating steadily towards the center and into direct line with Earth:

News sources in the Urals are beginning to report that numerous fragments of Friday's large bolide have been found. It's estimated that as much as 5% of the 56-foot-wide object survived the numerous explosions and plunge through the atmosphere. That doesn't sound like much, but that means up to one million pounds (500 tons) of space rock are spread over the strewn field downrange of the entry point. So far, the largest pieces being reported are about the size of golfballs (see image), with a lot of gravel- and pea-sized pieces scattered about. However, it's likely that some possibly much larger chunks (boulders?) made it to the ground, and are just waiting for a lucky person to find them.

meteorite

Now, you see that person touching the meteorite with bare hands? That's a no-no. If you should ever get so lucky as to witness a fall and find fresh fragments, there are some guidelines to follow to ensure your find has the greatest value to science--and possibly the greatest monetary value to you should you care to sell it:

  • Mark the exact spot you find the meteorite, using a GPS receiver if you have one.
  • Take photos of the meteorite in situ before you move it or pick it up.
  • Use new aluminum foil to collect the meteorite and to store and handle it.
  • Do not touch the meteorites with your bare hands, as they contain moisture, oils, and bacteria.
  • Keep magnets away from them (in order not to destroy any natural magnetism in the rock)
  • When you show the meteorites to others, minimize exposure to moisture (such as from people talking over it).
  • Keep plastics and rubber away from the meteorite. No storing in plastic bags, plastic containers, no touching with gloves.
  • Store the meteorites wrapped in aluminum foil in a clean (no smell) glas jar, covered by a sheet of aluminum foil. Put that jar in a bigger jar with closed lid with some desiccant on the bottom (if no other desiccant is available, one-minute rice will do). Allow the meteorite to dry out in this way to remove all absorbed water vapor.
And now you know...

BTW, a few months ago the BLM issued a memorandum on the collection and sale of meteorites from public lands. The new rules are pretty restrictive--for instance, you can't legally sell any meteorites you find unless you have a land use permit--so you may want to acquaint yourself with them before you head out onto government property.

(For what it's worth, divers searched for a rock beneath that large hole in the ice covering Lake Cherbal, but were unable to find anything. However, they admit the water is murky, and the bottom is covered with several feet of mud, so they'll be going back in.)

Tropical Cyclone Outlook
16:00 PM RET February 17 2013
=======================================

In the Mozambique Channel:

0610Z ASCAT swath shows a broad clockwise circulation 15-20 knots locally 25 knots in the southeastern quadrant extending from 15S to 21S with no obvious low level circulation center (weak winds area extends over 140 NM diameter). 0930Z METOSAT imagery shows a small low level vortex near 18.3S 41.0E but it is not sure that it is the main one. Minimal central pressure is estimated at 1001 hPa. Convective activity is weak and fluctuating near the central area and is mainly located up to far in the northeastern quadrant within the monsoon flow.

This low is slowly shifting south southeastwards at about 8 knots in a very favorable environment to intensify under the upper level ridge. Vertical wind shear is weak, upper level divergence is good mainly sustained poleward in relationship with an upper level trough transiting south of 33.0S.

The Low is expected to keep on drifting slowly southwards within the next 36 to 48 hours towards a weak in the subtropical belt and is therefore expected to regularly intensify under the upper level ridge and over high energetic potential seas

Beyond 48 hours, available numerical weather prediction models diverge a lot. ECMWF, GFDN and UKMO purpose a westwards then northwestwards tracks under the steering influence of the mid level ridge building over the Austral Africa.

GFS model purposes a globally southwards then south-eastwards track that cruises oversea in the south of Madagascar and then that evacuates in the extratropical area.

Depression se Comblant Former GINO:

Low level circulation center is now bad defined and elongated.

At 1000Z, MSLP is estimated at 1007 hPa and the circulation is centered near 23.8S 87.0E, moving now westwards at 7 knots on the northern edge of the subtropical high pressures.

The residual low is expected to dissipate within the next 48 hours.

Near gale Force winds 30 knots and locally gale force winds 35 knots should however exist within the next 24-36 hours in the southern semi-circle in relationship with the gradient with the subtropical high pressures

For the next 72 hours, potential for development of a tropical depression in the Mozambique Channel is good.

Earth Image of the day






Roughly 300 kilometers (200 miles) east-southeast of Tehran lies Iran Dasht-e Kavir, or Great Salt Desert. To the untrained eye, Dasht-e Kavir looks like a place that has been bone-dry since the dawn of time. But to the well-trained eyes of a geologist, this desert tells a tale of wetter times. Tens of millions of years ago, a salt-rich ocean likely occupied this region, surrounding a microcontinent in what is now central Iran.

The Advanced Land Imager (ALI) on NASA Earth Observing-1 (EO-1) satellite captured this natural-color image of Dasht-e Kavir on October 15, 2011. The top image is a wide-area view, and the area outlined in white is then shown in the close-up view below.

Dasht-e Kavir is a complex landscape, but it can be mostly explained by the invasion and subsequent evaporation of an ancient ocean. As the ocean dried up, it left behind a layer of salt as much as 6 to 7 kilometers (4 miles) thick. Salt has a fairly low density, so if a layer of new rock buries the salt layerand if that overlying rock is soft enough the salt can slowly push up through it and form domes.

As its name implies, the Great Salt Desert is rich in salt domes, or diapirs. Geologists have identified about 50 large salt diapirs in this region. Like any other surface feature, a salt dome is subject to erosion. Wind and rain scrape away particles of rock, gradually wearing away the top of the dome and exposing it in cross-section.

But erosion is not the only force at work in this region. In the close-up view, we can see north-south-trending structures, some raised and some lowered. Callan Bentley, a geologist at Northern Virginia Community College, identifies them as folds or fault zones that run parallel to the trend of the region mountains. Bentley attributes the deformation of the salt domes to plate tectonic activity that has occurred since the salt domes formed. Bentley describes the landscape as a Ca palimpsest tale that helps constrain the age of the diapirism to pre-folding.

Can't seem to post the video so am adding the link HERE

Astronomy Picture of the Day

Explanation: There it goes. That small spot moving in front of background stars in the above video is a potentially dangerous asteroid passing above the Earth's atmosphere. This past Friday, the 50-meter wide asteroid 2012 DA14 just missed the Earth, passing not only inside the orbit of the Moon, which is unusually close for an asteroid of this size, but also inside the orbit of geosynchronous satellites. Unfortunately, asteroids this big or bigger strike the Earth every 1000 years or so. Were 2012 DA14 to have hit the Earth, it could have devastated a city-sized landscape, or stuck an ocean and raised dangerous tsunamis. Although finding and tracking potentially dangerous asteroids is a primary concern of modern astronomy, these small bodies or ice and rock are typically so dim that only a few percent of them have been found, so far. Even smaller chunks of ice and rock, like the (unrelated) spectacular meteors that streaked over Russia and California over the past few days, are even harder to find -- but pose less danger.

The image above shows the Owl Cluster (NGC 457) in the constellation of Cassiopeia as viewed from Turin, Italy on the evening of November 12, 2012. It's approximately 8,000 light years away and is also referred to as the Kachina Doll Cluster or ET Cluster. Most of its 150 or so stars are dim (magnitude 12 or fainter), so its two most prominent stars (magnitude 5 and 7) are thought of as bright eyes. Because there are few dust clouds in the direction of Cassiopeia, star fields appear richer than in apparently nearby constellations, Perseus for example, where such clouds are more noticeable.

Forecast discussion out of Des Moines anticipating a mess:

YIELDING THE POSSIBILITY OF LIGHT FREEZING RAIN ON TOP OF THE FRESHLY FALLEN SNOW. THEN...AFTER THE DRY SLOT WORKS THROUGH...ANOTHER BURST OF SNOW IS LIKELY AROUND THURSDAY NIGHT AS THE CENTER OF THE LARGE LOW PRESSURE SYSTEM MOVES OVER THE AREA. THIS WILL RESULT IN SEVERAL HOURS OF ACCUMULATING SNOW AND STRONG WINDS ON THURSDAY...FOLLOWED BY SEVERAL HOURS OF EITHER LIGHT SNOW OR LIGHT FREEZING RAIN STILL ACCOMPANIED BY STRONG WINDS...THEN MORE LIGHT TO MODERATE SNOW THURSDAY NIGHT INTO FRIDAY MORNING WITH WINDS DIMINISHING SLOWLY UNTIL THE STORM PULLS AWAY LATE FRIDAY. ALL IN ALL IT WILL BE A MESSY AND HAZARDOUS STORM SYSTEM AND ALL INTERESTED PARTIES SHOULD MONITOR FOR FORECAST UPDATES AND POSSIBLE WATCHES/WARNINGS OVER THE NEXT SEVERAL DAYS.
