ATL HANNA: Extratropical - Discussion

[Bocadude85]

That ULL is tearing Hanna to shreds. It's be nice if it'd do the same to Gustav.

Yes and no. It's exposing the center but the system as a whole is very vigorous and pulsing deep convection to the east. It's just a matter of time until the conditions will improve (unfortunately).

On a fecitious note I would say the ULL has decided to go after Gustav now and has given up on Hanna --- it seems to be moving inarguably west or WSW now...towards Gustav..

Usually in this part of the Atlantic the ULLs dominate but now they appear outnumbered with the Gustav-Hanna tagteam

Yes it would appear that the ULL is slowly pulling to the west now...

I thought you were nuts with that ULL. But in the last couple frames you can see a west movement. I'm not looking at another loop this whole weekend. It gives me a headache. Be back on Labor Day.

Yep the ULL seems to be drifting away to the west, very slow motion however and Hanna still getting closer to the ULL.

good lord, its not even sept one and we have the media and some residents going bonkers, based on past history there could be alot more to come for this part of the world like well into october

I don't see how the calendar has anything to do with the media and residents going bonkers.
It's based on what is being said by the Pro Mets, NHC and models and has nothing to do with the date.[/quote]

my point is some people and some media need to chill out, get hyped up when its required not now, are they going to be hyped up for the next 6 weeks

[Chigger_Lopez]

Has anyone in S. Florida noticed how the weather seems to have changed today. No thunderstomrs at all today, perfectly sunny with nice light breeze from the East. Looks like the High is definitely sitting on our location. Nice weather, and that could change. . .

i noticed it was hot and sunny again with easterly flow like yesterday but i live by the beach and we have alot of days like that

No.
Once this scare is over; either by Hanna coming or not coming; things go back to normal until next time.

My point is just that the calendar has nothing to do with it and the fact that it is the last week of August and we still have about 6-8 weeks left is irrelevant to the coverage and should not be of concern.

If this situation were happening on June 3rd or November 3rd or August 28th means nothing. It is the situation and not the calendar that dictates the coverage.

I see no need to chill at all by the media.
The situation will play out.
It is a matter of supply and demand.
There is a supply of concern and demand says that the media reacts to it.
Simple as that to me.

That isn't the supply & demand theory I learned in MBA school, sounds more like third grade economics to me.

I know I should ask this in the TA forum but since there is so much discussion in this thread about the UUL, can some one please explain what it stands for and how it works against a tropical system?

Because it was clearly pointed out and quite obvious, I was able to pick it out in the link on pg 32 but normally, I am lost (much as I am now). I did google it under meterology but got nada. Thanks in advance.

ULL stands for upper level low, also known as a TUTT.

http://en.wikipedia.org/wiki/TUTT

The main negative is lots and lots of shear, as we are seeing with this storm.

[HURAKAN]

ULL = Upper-Level Low or system of low pressure in the upper part of the atmosphere.

It produces strong winds in the upper atmosphere and because tropical systems are vertically aligned, they need the winds in the upper and lower atmosphere to be similar. In this case, since the winds in the upper atmosphere are stronger than the winds in the lower atmosphere, it causes shear and displaces the convection.

I thought you were nuts with that ULL. But in the last couple frames you can see a west movement. I'm not looking at another loop this whole weekend. It gives me a headache. Be back on Labor Day.

We were looking at the low at the office. My coworker commented on the slight west movement recently. On a 24hr loop, we put the crosshairs on the center at frame 1 and looped it to frame 45. Looking at the left side of the crosshairs there is a bit of convection that covers up the western side of the low center but the eastern side remained rock-solid in the same location. We could detect not one bit of motion in 24 hours. Seems like it's drawing Hanna (which in no way is still a TS) into the center of the upper low. Will be interesting to see what kind of hybrid system results.

Is it possible for the llc to survive under an ulll, I'm trying to understand this but do not know enough and hope you can answer the question as I know it was asked earlier and it was not answered.
Thanks

It's a shame we are about to loose visible.

[cpdaman]

don't think it's drawing it in wxman57

last four frames you can see the LLC has stopped moving west

[HurricaneQueen]

Thanks, Brent and Luis. You guys are the GREATEST. I really understand exactly what you said and will save the explanations for future reference and also research TUTT. Each year I think I understand more but forget most of it by next season.

To stay on topic, it looks as if Hanna may have a shot at going right under the UUL as it pulls NW (what I see).

Again, thank you!!!!

convection now over right side of LLC

also since 2045 you can see hanna is just drifting N

and yes i feel like a dork highlighting my own post

Can't tell on that loop. Looks like the LLC is moving west but the displaced convection is staying in the same location.

Our local met (he is ACTUALLY a good one) said a couple of nights ago that the area of disurbed weather (now Hanna or soon to be TD 8 again) and the ULL would COMBINE.
Is this what you are alluding to in the part of your post that I "bolded"?

Can this occur?
Can you explain this in laymen's terms??

Thanks!
