Atlantic Tropical Action 2011 - Part III


Recommended Posts

Back on topic...

I have been following the models since 2006, and I really can't remember it being this deep into the season and not having at least one model hinting at a system at some point in the future. Its just very odd to see the GFS and CMC not showing any long-range ghost storms...

JMO

The real meat of the season is, of course, 8/15-10/15. Even the gfs still doesn't even get there (only goes out to 8/9). So, this is no real surprise to me. We're currently at three NS, which is near average for mid-Aug.

His point, stupid though it be, was that last year the models were already showing fantasy storms.

Right. But the GFS got a major upgrade to its radiation scheme last year and the CMC got a major upgrade to its tropical radiation scheme this year. Both these changes were implemented specifically for reducing spurious tropical cyclone developments.

i was worried for a second after reading superstorm's posts, but i'm feeling better and better...the CFS is rockin at hr 852...just like last season

i remember last year when you posted a bunch of CFS links and it showed a bunch of recurve monsters. It verified pretty well too.

The CFS is hilarious...if you ever want to see a train of verde's on a model just queue it up around this time of year

One post and I'm up on the cross.

What a great enviorment! wub.gif

Don't worry I have thick skin. Been married for long enough.

It's not a big deal that fantasy canes aren't happening on models...the reliable indicators all say we are in for a blockbuster season. I don't remember how much you were around last season, but some of the hand-wringing that's going on during this period is reminiscent of what happened then. We all know what happened from about 8/20 through 10/15....it made all the worriers and doubters look silly.

One last post in this burst and then I am steering clear of the thread for awhile.

Several of you in your preseason thoughts/musings/forecasts said we'd have a quick start but then a quick shutdown to the season...was that prognostication solely ENSO related and now out the window given what happened, or are there other things which factor in? Are you still sticking to your guns?

Who was on that train besides wxwatcher91? His ideas were based on the QBO switching phase in September.

OT

I wasn't around last year. The last thing I want to do is bump heads with anyone. I'm just here to get some of the best information available on the web and maybe, once in a blue moon...throw in my amateur opinion. Although, it seems whenever I post something with weak background I get *bleeped* on quite severely. Not used to that yet.

Hate to get even father off topic, but I do enjoy your posts Kush. Comedy does lighten slow times...

I'm gone..

This hand-wringing happens every year. My confidence in a significantly-above average season has increased as the season has progressed, and if anything my 15/9/4 numbers will probably be increased at the next entry to the tropical contest.

I'd be confidant in that too... you just need more of these weak tropic systems to form in the upper Atlantic ocean :arrowhead:

Based on my somewhat limited knowledge of such things, we will have to wait for the current attempt at an MJO pulse moving into the western Pacific to either propagate east (such as what the Empirical Wave Propagation Model shows) or collapse (such as the CFS and GFS try hinting at) for high heights and large scale subsidence over much of the tropical Atlantic to weaken, meaning we probably won't see anything interesting roll off Africa in the short term.

Talk about disagreement on how this attempt at an MJO pulse plays out, either way:

vs.

(although either outcome would result in a significantly improved Atlantic by August 15th)

Looking across Africa, the next distinct and convectively active wave in line to roll off in 4-5 days is located near 10E:

Right now there is no model support for significant development, which seems reasonable given the strong ridging over much of the eastern Atlantic, although both the 12z ECM and 0z GFS keep the wave trackable until at least 40W as an area of increased vorticity and moisture:

12z Euro @144 hours (wave axis looks to be just passed 30W):

0z GFS @132 hours:
