wind data in the Windwards...

[Weatherboy1]

We're just starting to get some potentially interesting wind data out of the Windwards ... though it's too early to say for sure. Stations in Trinidad reporting falling pressures and winds starting to come out of the W/NW. Barbados reporting ENE winds at about 15-20 mph. The text below only covers a few hours worth of data. But if we get more and more W, NW or N wind reports out of the Southern Windwards, it would signify to me that we do indeed have a surface circulation/low, not just an MLC...

Call me a sucker but it's looking pretty good to me.

use this:



updates hourly and the time is in Z/GMT.

Cool Thanks. Am I right in thinking that there could be a West wind but when moving too quick it could be negated by the fast motion?

If you subtract the forward speed you should still be able to get a relative velocity.

Thermodynamically the system should not care what the actual wind speeds are at the surface.

SST's are a little cool in the southern Caribbean but with a fast WNW track it wouldn't take long to get into favorable conditions.

These two buoys are interresting to follow the passage of this wave

[vbhoutex]

TROPICAL WAVE LOCATED 400 NM E OF THE WINDWARD ISLANDS...OR NEAR THE
FRENCH GUIANA/SURINAME BORDER...ALONG 54W S OF 16N MOVING W 20-25
KT. THIS MATCHES EXTREMELY WELL WITH THE CAYENNE SOUNDING WHICH
SHOWS A WAVE PASSAGE BETWEEN 00Z AND 12Z TODAY...BUT ONLY IN THE
MID-LEVELS BETWEEN 400 AND 700 MB AT LATITUDE 5N. SATELLITE IMAGERY
SHOWS A WELL-DEFINED MID-LEVEL CIRCULATION RACING TOWARDS THE SRN
WINDWARD ISLANDS...WITH TSTMS CLUSTERED CLOSELY NEAR THE CLOUD
CENTER. HOWEVER...THE 09Z QUIKSCAT PASS SHOWS NO LOW-LEVEL CENTER
WITH E/NE WINDS BLOWING THROUGH THE SYSTEM. SCATTERED MODERATE
CONVECTION FROM 9.5N-14.5N BETWEEN 55W-59W. SHOWERS/TSTMS WILL BEGIN
TO SPREAD NWWD ACROSS THE WINDWARD ISLANDS THIS EVENING...THEN
ACROSS THE LEEWARD ISLANDS AND ERN GREATER ANTILLES EARLY TUE
THROUGH THU.
