看了一下內文 登陸地應該是越南的胡志明市南端

REMARKS:
160300Z POSITION NEAR 9.0N 106.9E.
TROPICAL DEPRESSION (TD) 01W (ONE), LOCATED APPROXIMATELY 112 NM
SOUTH-SOUTHEAST OF HO CHI MINH CITY, VIETNAM, HAS TRACKED WESTWARD AT
08 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A DECAYING, FULLY-EXPOSED, LOW-LEVEL CIRCULATION
CENTER WITH NO DEEP CONVECTION. THE CURRENT INTENSITY IS ASSESSED AT
25 KNOTS BASED ON DVORAK INTENSITY ESTIMATES OF 25 KNOTS, CONSISTENT
WITH THE WEAKENED STRUCTURE. TD 01W IS TRACKING WESTWARD UNDER THE
STEERING INFLUENCE OF THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE TO THE
NORTH. TD 01W WILL CONTINUE TO WEAKEN WHILE TRACKING WESTWARD AND IS
EXPECTED TO MAKE LANDFALL OVER THE SOUTHERN TIP OF VIETNAM BY TAU
12. DUE TO THE MARGINAL ENVIRONMENT AND INTERACTION WITH LAND, THE
SYSTEM IS EXPECTED TO DISSIPATE BY TAU 12. THIS IS THE FINAL WARNING
ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE
SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 160000Z IS 6 FEET.//

可見光雲圖看，LLCC瓦解，並登陸越南

請問一下，甚麼情狀下熱帶擾動減弱後又增強用原名？去年1619艾利減弱後又增強卻要改名？:dizzy:

周子堯@FB

風速又增到30KTS了，JTWC 03z2二度編為01W

dom

現時 01w 站的位置有點 ... ...

JTWC再度發布TCFA

雖然被切得支離破碎
但低層環流中心還是相當明顯

2. REMARKS: THE AREA OF CONVECTION (REMNANTS 01W) PREVIOUSLY LOCATED
NEAR 11.7N 111.9E IS NOW LOCATED NEAR 10.4N 111.1E, APPROXIMATELY
260NM EAST OF HO CHI MINH CITY, VIETNAM. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A PARTIALLY-EXPOSED, WELL-DEFINED LOW-
LEVEL CIRCULATION CENTER (LLCC) WITH DEEP CONVECTIVE BANDING OVER
THE WESTERN SEMI-CIRCLE OF THE LLCC. A 132249Z SSMIS COLOR COMPOSITE
IMAGE SHOWS THE BULK OF THE DEEP CONVECTION SHEARED OVER THE
NORTHWEST QUADRANT DUE TO SOUTHEASTERLY VERTICAL WIND SHEAR (VWS),
HOWEVER, CONVECTIVE BANDING HAS BEGUN TO WRAP INTO THE WEST QUADRANT
OF THE LLCC. RECENT ASCAT DATA INDICATES 25 TO 30 KNOT NORTHERLY
WINDS ALONG THE WESTERN PERIPHERY OF THE SYSTEM. UPPER-LEVEL
ANALYSIS REVEALS A MARGINALLY FAVORABLE ENVIRONMENT WITH DIFFLUENT
POLEWARD OUTFLOW OFFSET BY MODERATE VWS, AND SST VALUES OF 27-28C.
DYNAMIC MODEL GUIDANCE SHOWS A SLOW SOUTHWESTWARD TRACK, ALONG THE
COAST OF VIETNAM, OVER THE NEXT DAY WITH WEAK DEVELOPMENT. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS HIGH.
