Dr. Jeff Masters' WunderBlog

Winter forecast
Posted by: Dr. Jeff Masters, 16:47 GMT le 15 novembre 2006 +3
Hello, Aaron here. Dr. Masters is on vacation and has taken an oath NOT to blog while out. He did leave some blogs for me to post periodically during that time. Here's the first one:

This Fall's ongoing El Ni�o event shows no signs of going away, and may grow stronger, according to the latest El Ni�o advisory issued last week by NOAA's Climate Prediction Center. The strength of an El Ni�o event is measured by how far above average the Sea Surface Temperatures (SSTs) in a region near the Equator off the Pacific coast of South America are. These SSTs are about 1 degree C above normal right now, qualifying this as a moderate El Ni�o event. A weak El Ni�o event has SSTs .5 degrees C above normal, and a strong one, 2 degrees C above normal. The strongest El Ni�o on record, in 1997, had SSTs 2.5 degrees C above normal.

The SSTs in the El Ni�o region are forecast to remain between .5 C and 2.0 C above normal through springtime by all of the El Ni�o models, so we can expect typical El Ni�o weather throughout this winter. This likely means warmer than average temperatures over western and central Canada, and over the western and northern United States. Wetter than average conditions can be expected over portions of the U.S. Gulf Coast and Florida, and drier than average conditions in the Ohio Valley and the Pacific Northwest. Global effects during November through March will likely include drier than average weather over Malaysia, Indonesia, the tropical North Pacific, northern South America, and southeastern Africa, and wetter than average conditions over equatorial East Africa, central South America (Uruguay, northeastern Argentina, and southern Brazil) and along the coasts of Ecuador and northern Peru.

It was a surprise to me to look at the global temperature forecast for the winter (Figure 1) and see NO areas with an above average chance to be cooler than normal. Usually, there is at least one region of the globe expected to be on the cool side of things. If this forecast verifies, 2006 should rank as one of the five warmest years on record, and may challenge 1997 and 2005 as the warmest year on record.

skyepony, in that link, what does RAOB mean? it mentions it and then marginal instability...
334. Skyepony (Mod) 02:49 GMT le 16 novembre 2006    
I'm hoping it doesn't get too crazy too. sounds like the area around SC could have it worse.

that is the largest swath of cold cloudtops I have seen in a long time. 30-40 miles wide it seems off florida's west coast.

nite, all.

Saw a show on the History channel last night on radical climate shift that suggests the global warming trend we have experienced this last 100 or so years is natural. But it also suggests the warming trend of the last 40 years has been so marked that continued acceleration of the earth's warming could trigger another Little Ice Age like the one that started at the end of the medeival period in Europe.

It was the first thing I have seen which recognises that man did not necessarily CAUSE the global warming trend.

On earthquakes and eruptions - wouldn't u agree that either is more likely to impact our weather rather than be influenced by the weather?

let's not talk about global warming. the earth goes through natural cycles. we are probably contributing to a warming trend and we need to try and reduce our emissions. however, other countries are becoming industrialized and will find the cheapest way possible to meet it's energy needs. we can't control the earth or thr weather.

now how bout this severe weather coming for the SE United States....
342. Skyepony (Mod) 03:18 GMT le 16 novembre 2006    




There was some yellow hail boxes, but they aren't showing up with the preview. The white squares is lightning strikes, the bigger the more recent. Lightning is well preceeding this one.

343. borlando 03:23 GMT le 16 novembre 2006    
that lightning (along with the rest of the activity) should move NE correct? with the general motin of the front being on an eastern path.

I am a weather idiot, I just enjoy it immensly.
345. BahaHurican 03:30 GMT le 16 novembre 2006    
I think GW is an interesting topic mainly because of how it is likely to affect our weather, both in the short and long term. However, isn't it potentially related to the blog topic???

On the system currently affecting the eastern US - I wonder how much of that energy will remain when the tail end of it trails its way across the Bahamas and WCar?

346. Skyepony (Mod) 03:31 GMT le 16 novembre 2006    
I'd say ENE. Here's the Nexrad loop out of Tampa. It has arrows that denote direction, particularly stronger cells, the lightnin & hail.

Baha this was from this afternoon's ECFL NWS discussion....
WITH A
CUT OFF UPPER LOW MOVING OFF THE SE U.S. COAST TUE. RESULTING SFC
LOW WELL OFFSHORE WILL ONLY REINFORCE THE COOL DRY ATMOS.

Here's the most recent one. Doesn't really go into tommarrow & the low, just what's coming tonight.

Been kinda watching that rainbow gulf most the day...wonder if the cut off low isn't starting to happen in the BOC, that blob down there has only apeared since this afternoon. Hadn't read this evening's discussion or looked at buoys down there...any thoughts? Anyone wanna check out a blob..in an area of rather high shear? Looks like it'll travel east abit before it would be cut off.

I'll be back in a bit.

Skye,

I looked at that. Doesn't really move Sward, does it? Interesting abt. the U level divergance, obviously a key player in the current severe threat. I guess we'd need to see a similar level of instability in the SW Car to have any development along the lines of the CMC forecast . . .
