Low pressure developing south atlantic

#1 Postby Matt-hurricanewatcher » Thu Nov 24, 2005 7:52 am

Near 17.3 south/37.2 west. There seems to be a low pressure area developing. With deep convection over it. I'm watching it closely....

Wow the sst are much colder then they are durning March down there...Only a short window at the moment for development. Just think if this was Jan-April there might be a pretty good chance for development.

Yes, if it was summer it would have a much better chance of developing than it does right now as being spring it hasn't had much time to warm up the waters yet. Otherwise, it looks pretty decent for where it is.

The visible shows there is a low pressure/broad LLC, with convection. Centered near 15.8/36.5. There seems to be some curve banding. The FSU GFS shows its a warm core system. Quickscats not yet confirming it...

But as it moves southward it starting to run into cooler SST/shear.

I think we will see a few systems this year for the south Atlantic. I think some of that energy is going to get into the south Atlatnic. The visible shows a broad but intact LLC. GFS out of FSU shows its warm core. quickscat data doe's not quite show it yet.

This was over the Barents Sea in 1987 just north of the Norwegian coast. :wink: :lol: http://nsidc.org/arcticmet/images/patterns/polarlow_small.jpg

I agree that is a polar low. But this is forming over 26 to 27c waters. There doe's appear on visible to be a broad LLC. In the FSU Gfs shows it to be warm core(Even it missed it to the south)

I think as the south atlatnic warm up/shear decreases. The energy is going to move into the south atlantic. 2003 had a active season with 16 named storms. Then boom 2 systems for the south Atlatnic.
