Tuesday, April 22, marks Earth Day. As has been my tradition, on Earth Day I share some of my favorite photos wunderground users have uploaded over the past year. The Earth's atmosphere is a fantastically beautiful and complicated creation, and I thank all of you who took the time to share the spectacular things you've seen with the rest of us!

I'll be back Wednesday to talk about the demise of this year's La NiƱa.

Hydrus, I'm only novice, and defer to the gurus here. My opinion, at least from a perspective from the ITCZ, is that winds come from different directions there, causing convergence and lift, creating activity. Where the QBO falls, I'm not sure; but, apparently there's some strong observances that shouldn't be ignored, considering the values in 2005 and the strong activity.

This was my conclusion from last night's discussion; but, I could very well be completely wrong and, further, it would not surprise me one bit! lol (I think I'm saying the same thing as STL, just worded differently.)

2005 had record negative values and super active season. Therefore, one can conclude negative values support an active season. Negative values indicate strong westerlies influence. Strong westerlies = active season.

The greater the "anomaly," the greater the significance of the QBO values. If the QBO value is negative, a positive anomaly would mean the westerlies are stronger. If the QBO is negative, but with a negative anomaly, the easterlies would be stronger. However, that does not necessarily indicate a less active season unless the anomaly causes the QBO value to rise above the "0" point value or higher, in which case the easterlies are favored and a less active season is presumed likely.

I'm out for a bit. Catch up later. Again, thanks, all.

I'm really confused, i always thought that westerlies winds was bad for tropical formation. Because they tend to be blowing the oppisite direction most storms travel. Yikes...lol

MOONLIGHTCOWBOY-I been reading the blogs on the Q B O also.I,m trying to understand all of this information.This I do know,it seems during the La nina years the winds are more likely to travel in the same direction at all heights of the atmosphere that play critical rolls in hurricane formation as waves and disturbances move from the coast of Africa toward the west Atlantic.Do you agree with this?

Thanks, STL. I think we're saying the same thing. (but, I wouldn't bet on it, knowing me, lol) Thanks for yours, StormW's, and alls input. Maybe, I'll get a good grasp of it soon.

Hey Storm - shot you an email but figured I'd ask you here too - that thing off the coast - any chance it's going to affect Columbia SC this weekend? I have a race - boat is already rigged and sitting there and if it's going to blow, I'm going to have to go take the mast down and get it home...not sailing in bad weather...

GLOBAL COOLING

Over the past year, informal evidence has begun to stack up supporting a global cooling trend. For example, recently Baghdad saw its first snowfall ever, China has recorded its coldest winter in 100 years, and North America has more snow cover this year than it has had in the last 50 years. Additionally, record low temperatures have been recorded in Texas, Florida, Minnesota, Mexico, Australia, Iran, Greenland, South Africa, Greece, Argentina, and Chile, to name a few.

Recently, supporters of a global cooling theory were boosted with the release of data from all four global temperature tracking outlets (Hadley, GISS, UAH, and RSS). All agree that over the past year temperatures have dropped abruptly over the entire earth.

The entire cooling amount ranges from 0.65C to 0.75C . This amount is significant enough to eliminate almost all of the warming recorded over the last 100 years. Most significant is the fact that this cooling occurred over one year. All four tracking outlets confirmed that this is the fastest temperature shift ever recorded, either up or down.

Good moring and thanks, StormW for trying to get the QBO discerned.

In post #150 last night, I thought I had understood; but, now I'm not so sure.

I thought the negative values meant the westerlies were more favorable for more/more intense activity? But, now, in this last post, you seem to indicate that the negative values represent the easterlies. I thought the "anomalies" were the changes we would observe, and also, 30mb and 50 mb are quite close and there wouldn't be that much difference there.

Again, plz, see where I'm wrong in post #150, and set me straight! Thanks, Stormw!

Big time trouble for the economy is coming...

APR 20, 2008 9:06PM
Bank Of America Will Not Renew Sears' $1 Billion Line Of Credit

Comtex News Network

Apr 21, 2008 (financialwire.net via COMTEX News Network) -- April 21, 2008 (FinancialWire) Sears Holdings Corp. (NASDAQ: SHLD), which operates Kmart and Sears stores, said that Bank of America Corp. (NYSE: BAC) will not renew its $1 billion long-term credit amendment under its existing terms.

Banks are tightening credit lines to retailers amid a weakening economy, and HSBC (NYSE: HBC) and Bank of America said they will either cancel or not renew lines of credit to women's apparel retailer Talbots Inc. (NYSE: TLB).

Morning everyone :)

An interesting ULL is east of North Carolina but otherwise there appear to be no physical features to talk about in the Atlantic at the moment...

Concerning the severe weather risk...

A squall line of thunderstorms with high liquid content (aka VIL) currently extends horizontally from Marshfield, Missouri, to just west of Eminence. Most of the cells embeded along this line are SVR warned, up to 2.25 inch hail possibly with the strongest. A vertical extention of this squall proceeds up north past St. Louis, where five SVR's are out for portions of the metropolitan area.

The SPC has issued a slight risk for today and tomorrow, but tomorrow has me more concerned in regards to supercell activity. Based on WRF forecasts for tomorrow, a weak to moderate CAP will be in place, but will be broken by high Theta E combined with daytime heating. Along the center of the event (Dallas Metro/Southern Oklahoma) there will be in place an extremely unstable airmass, with SBCAPE values exceeding 2000 J/kg, defined as "large". Helicity will be exceeding a value of 350, meaning that the environment will have the energy needed for supercells.

Although I do think the current 30% area should be extended to include the Oklahoma/Texas panhandle as the WRF and RUC are showing favorable conditions (possibly even more unstable than in the current area) there also.

However, I agree with the SPC in that this should not be a moderate risk event just yet. Based on what this area gets in terms of convection today, the energy may be drained straight out of the atmosphere. This "ongoing convection" will fire up this evening and may continue into tomorrow. This will be the deciding factor in whether tomorrow will be "big" or not.

You gotta be kidding me.....wow.


Welcome to the "global economy"....Exon/Mobil/GM/Ford, etc....Have been in China for the last few decades helping the Chinese develop their "non Earth Day" pollutant economy, selling gas guzzling cars by the thousands, helping develop oil drilling technologies, and, we here in the US (and other parts of the world) are paying through the teeth for gas and basic commodities......Does not make sense to me either............My Wife says this is like the movie "Rollerball" from the 70's....Corporations and Banks now rule the world and borders are becoming more irrellevant every day....

Wipro overcomes slowdown in US

Financial Times

China Petroleum & Chemical Corp and PetroChina Co are expecting to be awarded with monthly government subsidies starting this month to offset low fuel prices and refining losses. The losses have resulted from Beijing's tight fuel price control, which have limited the rise of domestic fuel prices. China Petroleum, also known as Sinopec, has already received state subsidies on two occasions, 4.9bn yuan ($700m) in 2007 and 7.4bn yuan in the first quarter.

Good Morning and awesome photos Dr. M; as far as your blog tommorow (on the demise of La Nina), let me guess the gist of it; at the current rate of subsidence, we will probably be looking at ENSO neutral conditions during the peak of the season?.....with an active Cape Verde season?....With the position of the BH being a huge factor this year in terms of potential threats to the Caribbean and U.S.?........

As far as Earth Day, and I have been blessed to live in Florida and view firsthand the natural beauty of Mother Earth, I only hope that our furture generations, including my own children, try to take good care of our Planet........I need to find the pictures to upload, but, as an avid fisherman in South Florida, my most memorable trips (and pictures)are of "flats" fishing trips in Florida Bay out of Flamingo in the Everglades.....I have never seen such natural beauty as I have witnessed leaving the ramp at sunrise, on "mirrored" waters and watching gators gently moving along the shoreline, Egrets and Herons flying by, and schools of mullet "flying" in the flats as pods of Porpises feed on them (oh, and Tarpon gently rolling just off shore waiting for me to gently present my fly)..........I hope yall got the picture..........Happy Earth Day

Just reviewed last nights disc. on QBO --really fascinating!! thanks fshhd post#163 for a wonderful post!! Happy Earth Day to all -- the trick is for us to be aware not just today, but everyday of our impact on the planet --and to try and leave just our footprints behind.

Looking at SST one would conclude that 50% of the Atlantic is normal to slightly cooler than normal especially in the SW Atlantic. The suspect of an active tropics does not seem likely IMO at this time.

so close to hurricane now

50 sustained winds x 1.15 is about 60 knots 1 minute.

Bureau of Meteorology - Perth
Tropical Cyclone Advise Number 12
03:00 UTC April 22, 2008

At 11:00 am WST a Tropical Cyclone Rosie [CAT 2] (980 hPa) located near 10.2S 104.9E has 10 minute sustained winds of 50 knots with gusts up to 70 knots. The cyclone is estimated to be 120 kilometres southwest of Christmas Island and moving south-southeast at 12 knots.

Dvorak Intensity: T3.5

Tropical Cyclone Rosie, although at category 2 intensity, is now moving away from Christmas Island.

Tides will continue to be higher than expected and will combine with large waves that may cause flooding of low-lying areas today.

While the risk of sustained gales has diminished there remains the possibility of squalls with gusts to 90 kilometres per hour today. The large swell is likely to continue tonight.

Tropical Cyclone Alerts
-------------------------
A Cyclone Warning has been declared for Christmas Island

Anomalies would be the same at either level (30 mb or 50 mb). It's hard to say which level is more important, especially since the relationship hasn't worked well in recent years.

I don't take this to mean that the QBO hasn't worked well in recent years, but rather the relationship between the 30mb and 50mb levels haven't worked well. But, I wouldn't think the anomalies at those levels would be considerably different anyway. Aren't they extremely close?

This is something STL posted ealier, see if this helps MLC...


The QBO massive switch 2005 vs 2006. The 3 most destructive and active months of any Hurricane season on record was AUG / SEPT/ OCT 2005. In those months the AUGUST of 2005 QBO value was the strongest Negative Value AUG value ever recorded (since 1950) and 3rd lowest of all time. The QBO value in SEPT 2005 was the lowest Negative QBO value EVER as was OCTOBER 2005. Now in AUG 2006 ( 9.10) the QBO was 35 points HIGHER than AUG 2005 .... In SEPT 2006 ( 10.20) the QBO Value was 37 points higher .... and in OCT 2006 the QBO value ( 10.86) was again 40 Points higher when compared to OCT 2005 . The point is that this massive swing in the QBO was NOT supportive of the forecast for a Much above Normal activity Hurricane season for 2006.

Stormdude, let's see, I'll try again here.

EXAMPLE:

2005 had record negative values and super active season. Therefore, one can conclude negative values support an active season. Negative values indicate strong westerlies influence. Strong westerlies = active season.


2005 was a very very active hurricane season, To this day i still believe there is something that we still don't know about that fueled all of those storms. There's something more to the mix than what we know.

Er actually its pretty boring now. It needs to be over warmer water to do any developing.


Not only that, Shear needs to keep dropping if it has any real chance at development, The more favorable the conditions are getting the more i believe it could indeed become Andrea the second....I will agree that it has a very evident circulation though, If it holds we could see some development, I doubt tropical, Likely Sub-tropical...

Sure, if the anomaly is positive, the QBO is out ofthe west and if the anomaly is negative, the QBO is out of the east.

The anomaly in 2006 (from April to the end of the year) was positive, so the QBO was out of the west.

Well, I'm a bit confused. The "anomaly" is what must be positive. But, negative values support the westerlies which enhance more/more intense activity.

It that a better conclusion?

Thanks, StormW! Have a good sleep!
