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.

Small aurora that started right at sunset tonight. Stayed just a stream for most of an hour. Hopefully we will see more in the next few days. You can see more Northern Lights photos in my folder here and at my web site www.northpolegallery.com

Just looking at the CFS model (Accuweather Pro Site)...it's calling for MSLP anomaly departures in most of the CATL during the Cape Verde season on the order of -1.5 to -2.5 mb

BBL.



Thats significant...

What the heck.....have a look at everything:

Huh? Is there something I'm missing? ...

EDIT: Oh I get it...nice image... :D Thought you were pointing out some anomaly.

After a good look, There appears to be 3 low-pressure areas....One being part of a trough.

GFS shows the stronger low pressure (west of Bermuda) absorbing the second (south of Bermuda).

None of the models show this transitioning to subtropical or tropical core. The NOGAPS has it venturing into that area, but by then it will be too far north and it will have to large a wind field to be subtropical or tropical.

Yeah, Flood, lots of variables. TONS of things, and you're exactly right. And, considering crude has been trading at $120 today (effectively double from one year ago), we certainly don't need an active season! Tough times ahead, I'm afraid!

-- Flood, you egghead! j/k ;P Yeah, you're right, absolutely; but, we've just been trying to discern if the QBO, in itself, acts a single, real discriminating factor in tAtl development conditions, similarly, with as much weight garnered as compared to El Nino or La Nina. There seems to be some school of thought that the QBO is a possible "key" determining factor in how the season may shape up. And, I'm not sure we're able to draw that conclusion, but apparently, it is quite relevant. In fact, I'm not sure (at least I haven't) we've gotten a good grasp of the QBO concept and what the anomalies mean. So anyways, it's interesting and good discussion, nonetheless - just adding it to the learning curve!



LOL, thanks, MLC! It would be nice if this was the one determinant, huh?

Sub-tropical Storm Ana was quite a bit better organized than both of the low-pressure areas currently out north and east of the Bahamas, As seen in the image Ana had something that both lows are lacking, Convection over the circulation....

Good point....however.....Ana took 3 days to attain that level of organization after the disturbance first formed. Our little low has only just come off of the coast, give it time lol, it's already quite impressive. Eventually we may see some more convection over the center of the circulation to spice it up and make things interesting.

The low-pressure area that is north of the Bahamas has some developing banding features, Not that it means much. It also appears to be moving south or southwest.

Good morning all.

What have we here, twin lows spinning up to the N and E of the Bahamas ?


Good Afternoon folks! It's very interesting to look on satellite and see two low-pressure areas spinning about, north and east of the Bahamas. As other's already mentioned, Shear is dropping quite rapidly and if it continues there is a chance that one of these may become Sub-tropical in nature, perhaps a depression. I will have a blog update on these two features later.

Funny, look at this, 0.4% TC formation probability off the Carolina coast lol. Probably because of the lowering shear and the 850mb circulation is very impressive.

Here's the shear map with 24-hour tendency. The blue dashed lines in the vicinity of the cut-off low mean shear has decreased 20-30kts in the last 24 hours, and may continue to fall due to the ULL getting completely cut-off from the flow pattern and becoming vertically stacked, hence lowering the shear as wind directions aloft coincide with those at the surface. This feature has at least 48-72 hours to meander around slowly moving SE, and could become a rather interesting little rogue system. We've seen it before, SSTs are way under TS threshold but sub-tropical systems need very little to become quite beastly. Something to entertain us a bit in expectation of the season to come.

I'm an egg, so I don't even know why I'm getting into this QBO discussion, but it seems to me that basing conclusions on the 2005 season alone is a little less than reasonable; how large a data set are we talking about? How many years of QBO data are available? In addition to that, what other elements were in place? Any other commonalities in high storm frequency, negative QBO value years?


-- Flood, you egghead! j/k ;P Yeah, you're right, absolutely; but, we've just been trying to discern if the QBO, in itself, acts a single, real discriminating factor in tAtl development conditions, similarly, with as much weight garnered as compared to El Nino or La Nina.

Kind of reminds me of a storm about five yrs ago.

You mean (S)TS Ana in 2003?

Our Carolina Swirl probably will never be much more than that. It'll need much better structure down through the mid and surface levels to get anywhere, and the shear environment its in is not conducive. Its over some fairly cool SST's, but if it drifts further south over the Gulfstream it'll be over some warm 25C waters, respectable, but still marginal for tropical development. It's a little early for blob watching folks.

What were the similarities between 03, 04, 05 and 07 aside from the QBO values, and what anomaly (ies) could be responsible for the 28 named storms in 05?

MOONLIGHTCOWBOY-I remember years ago Dr Grey saying that during El Nino seasons hurricane activity decreased about 40% because the Q B O (EQUITORIAL- STRATUSPHERIC- QUAZI- BIENNIAL- OSCILLATION)winds aloft were romoving all thunderstorm and shower activity away from the center of the circulations that occured over the Atlantic and carribean waters.

TS, I'm surely confused, too! But, I'm confident this group will get it figured out! I'm anxious to see their conclusions, too.

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.
