Possible tropical System Forming in the Bahamas?

[Air Force Met]

Is the system you are referring to the little spin we are seeing? ..Or that whole area in general?

The whole area...at this point any little spin without any stable covnection means nothing.

This place is going to be packed come june 1st.

Thanks for the information, Air Force Met. I agree on that the chances are very slim.

All of you passed the test in this thread well. Now let's wait for the real deal sometime in the future and skysummit we will have those long threads with 100 pages =comments,sat pics,models thread ones.

AFM:

Thanks.

I seem to remeber that at the SURFACE...high pressure related winds are weaker than low pressure related winds (again, if I recall correctly, this is a function of the PGF and Coriolis/Centrifugfal forces working differently in a high vs a low).

This dyanmic doesn't change aloft, does it?

How do anticyclones aloft compare to surface anticyclones? Do they also have a broader windfield than their surface "cousins"?

Thanks

NG, CMC Picks up on this system transitioning to a cold core system very well. Just so you guys have an example here ya go. Go to the cyclone phase and analysis page and check it out first.

maybe cause high pressure has to go "against" the flow of the earth spinning as to why it is lower...basically IMHO, the high pressure winds require more energy to get going and stay spinning clockwise here in the northern hemisphere than it is required for low pressures...

wow...18 pages...wow lol...just discissing...haha

either its me or a eye seems to be forming. anyways, the system is now rotating and headed towards Florida.

Wow! This is by far the most interest I have seen In April. Preseason is getting every one amped. Storm2K will have 200,ooo members in no time!

its like people come out nowhere.... i know but its cool i guess when u have a passion for hurricanes like i do its all good.

Brunota:

At the surface, the balance between the pressure gradient force, coriolis, centrifugal/centripetal force and friction means that a high is going to have lower wind speeds for a given gradient for a low. If you're interested, I can try to explain (though it might take another thread)

i dont care if you explain...i get what you were saying...lol

I know you're kidding heh? If not, you may be close to becoming a troll in the near future with these posts.

No it doesn't change. Remember, high pressure winds aren't weaker than low pressure winds, either. Winds are a function of their pressure gradient force only, regardless of whether they are in a high or low. It's just that you are much more likley to have a step PGF in a low than in a high...UNLESS you have a low next to a high increasing the PGF. Highs can't build to the extend that a low can depend before the PGF spreads out, which is why the wind field is weaker. Lows are creating a mini-vacuum, so air is leaving at a faster rate than it is filling, thus the pressure lowers as the PGF increases.

In a high, air is filling in faster than it can be moved out but it is a less violent process at the sfc and aloft than what is going on in a low, so the air has a chance to spread out...as does the PGF...and it occurs over a broader area...whereas the low deepens in a smaller area near the center. Thus...a broader wind field and weaker PGF in a high.

How do anticyclones aloft compare to surface anticyclones? Do they also have a broader windfield than their surface "cousins"?

They are the same. Again, it's a function of their PGF (and we call it CGF aloft...contour gradient force due to the fact we use contour maps instead of pressure maps).

I'm pleased none of us failed u

I have a big passion for hurricances, I can't wait to go to Florida State University and getting Degrees in meteorology, though I hav another year to wait before I go to college

[OuterBanker]

btw. TPC floater 1 is Fla and eastern gulf, floater 2 mid atlantic to nc. Are these the defaults?

This is an impressive discussion about not much. August should be scary.
