CMA相比JTWC顯得就認份認真的多,判定於00Z左右才登陸

台 风 预 报
预报：孙舒悦  签发：许映龙   2021 年  07 月  08 日  10 时
热带低压登陆越南清化
北部湾热带低压的中心已于今天（8日）上午7点50分前后在越南清化沿海登陆，登陆时中心附近最大风力有6级（12米/秒），中心最低气压为1002百帕。上午8点钟其中心位于越南清化境内，就是北纬19.6度、东经105.7度，中心附近最大风力有6级（12米/秒），中心最低气压为1002百帕。

预计，低压中心将以每小时20公里左右的速度向西偏北方向移动，并逐渐减弱消散。

（注：这是关于该热带低压的最后一次报告）

REMARKS:
072100Z POSITION NEAR 20.5N 106.1E.
07JUL21. TROPICAL DEPRESSION 08W (EIGHT), LOCATED APPROXIMATELY
46 NM SOUTHEAST OF HANOI, VIETNAM, HAS TRACKED NORTHWESTWARD AT
14 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS SHEARED CONVECTION TO THE WEST OF A POORLY
ORGANIZED LOW LEVEL CIRCULATION THAT IS NOW CROSSING OVER THE COAST
OF VIETNAM. THE INITIAL POSITION IS PLACED SLIGHTLY WEST OF THE PGTW
POSITION FIX AND THE INITIAL INTENSITY OF 20 KTS IS HEDGED SLIGHTLY
LOWER THAN THE PGTW CURRENT INTENSITY ESTIMATE OF 1.0 (25 KTS).
RECENT MICROWAVE IMAGERY SHOWS NO INDICATION OF ANY SIGNIFICANT
CONVECTIVE STRUCTURE REMAINING. DUE TO LAND INTERACTION AND HIGH
VERTICAL WIND SHEAR (>25 KTS), TD 08W HAS DISSIPATED AND IS FORECAST
DECREASE TO 15 KTS WITHIN 24 HOURS. 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.//
