mas o menos si que se comenta...unos 10 post esta tarde...

Hola,
Also someone else from Spain sent me this image and was wondering why the NHC failed to mentioned it

This 90L Today, Sunday 4 October



""[The National Hurricane center] seems to be naming a lot more than they used to. This year, I would put four storms in the very questionable category, and maybe even six. In the past, we would have waited to see if another observation supported naming the system. We would have been a little more conservative."

Neil Frank, National Hurricane Center Director, 1974-1987.

1. Aren't occluded lows a characteristic of mid-latitude cyclones and don't subtropical cyclones have characteristics of both tropical and mid-latitude systems, which has fronts.

2. Aren't occluded lows the sign of a decaying mid-latitude system.

3. Does the satellite presentation support this feature being tied to a front.

4. Is there a temperature contrast along 90L, the last time I check occluded lows have uniformed temperatures.

4. Subtropical cyclones have some sort of frontal feature to their NW.

5. QS showed the strongest winds near a very well define LLCC.


Systems near Greenland as I said before have warm-cores but they are not subtropical or tropical becuz they have more non-tropical features than tropical. For one, they are baroclinic.

You cannot use 23C to define a line, there is no line when it comes to classifying systems because not all systems are perfect. For instant, a tropical depression does not have specific winds of 30, 33, 36 mph, its either 25, 30 or 35 mph. And to say SSTs were too cold when it was 22C is an exaggeration, what is the biggest difference between 22 and 23C when the system is producing convection as if it was over 24C?

So how come Vince was classified over 23C, isn't the threshold for tropical systems 26C?

I am seeing comments about water is too cold and such and that really the only argument against 90L-ex. Now tell me, if the waters are too cold why is the system produce convection? You know what those cirrus clouds indicate? Those cirrus clouds indicate air is hitting the tropopause and has no where to go but outward (outflow). Mid-latitude systems don't have convective clouds that extend that far up that's why thunderstorm frequency drops dramatically in the high lats.

Another thing, the lapse rate, if the SSTs are that cool then the air directly above the sea surface should be cooler than the air aloft (temperating rising with height is a stable situation). The only way this system could produce such organize convection on each frame for 6 hrs, is if the lapse rate was decreasing with height (unstable situation), and in order for that to happen SSTs have to be warmer than the air aloft.

Some of my co-workers who have much more experienced than I am are dumb-founded as to why the NHC has not mentioned this system today. Something is not adding up and the last time I check I haven't had any mental problems, lol. This is utterly whack!
