我只懂一句: 風切很大

剩下交給版上前輩們 !



JTWC：LOW
(1) AN AREA OF CONVECTION HAS PERSISTED NEAR 6.3N 135.1E,
APPROXIMATELY 70 NM SOUTH OF KOROR, PALAU. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A BROAD LOW-LEVEL CIRCULATION CENTER THAT
HAS STARTED TO SLOWLY CONSOLIDATE WITH WEAK FORMATIVE BANDING ALONG
THE SOUTHERN PERIPHERY AND DISORGANIZED CONVECTION ELSEWHERE.
SCATTEROMETER DATA FROM 221452Z SHOWS A WEAK, (05-10 KNOTS) BROAD
CIRCULATION IN THE AREA AND A WESTERLY WIND BURST ALONG THE EQUATOR
JUST TO THE SOUTHWEST. A 230107Z TRMM MICROWAVE IMAGE SHOWS THE
CONVECTIVE ORGANIZATION OF THE SYSTEM HAS STARTED TO IMPROVE BUT
OVERALL REMAINS POOR. UPPER-LEVEL ANALYSIS REVEALS THE LLCC IS
EMBEDDED IN THE EASTERLY FLOW WHICH IS PROVIDING MODERATE OUTFLOW
AND MODERATE TO STRONG (20-30 KNOTS) VERTICAL WIND SHEAR. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
