93W JTWC: LOW
本帖最後由 SHYUDOL 於 2012-5-19 09:36 編輯
1) AN AREA OF CONVECTION HAS PERSISTED NEAR 7.1N 132.8E(93W定位),
APPROXIMATELY 125 NM WEST-NORTHWEST OF PALAU. ANIMATED INFRARED
SATELLITE IMAGERY SHOWS A WEAK LOW LEVEL CIRCULATION CENTER (LLCC)
WITH FLARING, DEEP CONVECTION. A 181152Z ASCAT IMAGE DEPICTS THE
EASTERN PERIPHERY OF THE LLCC WITH 10-15 KNOT WINDS. THE SYSTEM IS
IN A FAVORABLE ENVIRONMENT WITH LOW VERTICAL WIND SHEAR (10-15 KTS)
AND MODERATE DIVERGENCE ALOFT. HOWEVER, AN UPPER LEVEL LOW IS
SURPRESSING OUTFLOW NORTHEAST OF THE SYSTEM. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1009 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW
.
LOW~哦
