Tropical Weather Discussion

Tropical Weather Discussion for the Western North Pacific between

the Equator and 25N from 130E to 180. The following information is

based on recent satellite imagery/data, weather observations, radar,

and meteorological analysis.



...SPECIAL FEATURES...



None.



...OTHER WEATHER SYSTEMS...



NEAR EQUATORIAL TROUGH...

A Near Equatorial Trough starting at EQ165E. The Net hovers around 1

to 2 north and heads westward to 130 east. There are 2 noticeable 

embedded circulations in this NET. The first is southwest of Kosrae 

and the second is well south of Satawal. Convectively this trough is

mostly inactive save for the far west portion near Palau Reni, Palau

Wajag, Palau Bras and Aurora reef. This small convective region is

rather lack luster and is just showers.



OTHER SYSTEMS...

There are three zones of trade wind convergence, 2 of which are near

the embedded circulations of the NET. The first zones is in southern

eastern Micronesia, south of Pohnpei and Kosrae. This region is

having warming cloud tops that suggest the event is nearing

completion. The second convergence zone is south of Satawal, Ifalik,

and Eauripik. The major cell is in its death throws and is all but

gone, however to its west just a bit more cells are popping up. The

last one is south of Yap Proper and southeast of Palau. This is the

most vigorous of the convergence zones and is heading in the

direction of Sonsorol.



...DISCUSSION... 

For north of 10N a fairly dry pattern regime has set up and remains

for the region. Below 10N is where all the weather is. The NET is

expected to be relatively benign. THe convergence zones are where all

the action is. Lightning strikes were detected with the decaying

cells, so the new cells have some potential. Cloud tops in general

are warming across all 3 zones. This suggests the current convection

is coming to a close.
