98W Medium

AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR
21.3N 146.9E, APPROXIMATELY 380 NM EAST-SOUTHEAST OF IWO TO.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY REVEALS A COMPACT
CONSOLIDATING LOW LEVEL CIRCULATION WITH FORMATIVE BANDING IN THE
SOUTHERN SEMICIRCLE. A 282233Z METOP-A PASS INDICATES A POSSIBLE
CIRCULATION ON THE EASTERN PERIPHERY OF A SHARP TROUGH WITH 20-25KT
WINDS IN THE EASTERN QUADRANT WITH 10-15KT WINDS ELSEWHERE.
ENVIRONMENTAL ANALYSIS INDICATES INVEST 98W IS EXPERIENCING LOW
(<15KTS) VERTICAL WIND SHEAR, MODERATE EQUATORWARD OUTFLOW, AND WARM
(30C) SEA SURFACE TEMPERATURES. GLOBAL MODELS DO NOT RESOLVE INVEST
98W WELL AND THEREFORE DO NOT INDICATE THE DEVELOPMENT OF THE SYSTEM
AT THIS TIME. HOWEVER, THE DISTURBANCE IS EXPECTED TO TRACK
POLEWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS MEDIUM.

這隻應該就是昨天凌晨JMA編的那個TD


這麼一說昨晚我好像其實可以開貼..

老農民版夜神月

雲圖上跟北面的鯨魚颱風對比起來非常的迷你

晚上最新的風場掃描,結構的部分不錯,中心有明顯的閉合.過濾前的掃描LLCC東南側有幾根25KT的風旗

老農民版夜神月

早上的風場掃出大量25KT甚至30KT的風旗,惟LLCC似乎已變得沒有閉合
