有沒有可能再發展為輕颱?因為看雲圖,結構好像從新整合 |
儘管目前機構仍舊定位在沙巴沿岸,但沙巴西方的新渦度這半天以來逐漸深化並取代中心位置的渦度,再加上深對流於新渦度附近爆發,那位置的垂直風切更遠比周圍微弱,推測之後重新定位的機會不低。 TROPICAL DEPRESSION 1008 HPA AT 06N 118E WSW 10 KT. |
JMA 仍維持 TD。 TROPICAL DEPRESSION 1004 HPA AT 07N 119E WSW SLOWLY. 另外,JTWC 發布評級,認為一天內發展為熱低的機會為低。 AN AREA OF CONVECTION (THE REMNANTS OF TD 23W) PREVIOUSLY LOCATED NEAR 8.9N 121.7E, IS NOW LOCATED NEAR 6.8N 119.0E, APPROXIMATELY 175 NM SOUTH OF PUERTO PRINCESA, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A FULLY EXPOSED AND WELL DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) THAT IS DEVOID OF ANY DEEP, ORGANIZED CONVECTION. A RECENT 010210Z ASCAT PASS REVEALED 15 TO 20 KNOT WINDS ALONG THE LLCC WITH A LARGE 20 KNOT WIND FIELD ASSOCIATED WITH THE NORTHEAST MONSOON WELL TO THE NORTHWEST OF THE LLCC. UPPER LEVEL ANALYSIS REVEALS A POOR ENVIRONMENT WITH MODERATE TO STRONG (20 TO 30 KNOTS) VERTICAL WIND SHEAR AND WEAK OUTFLOW. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW. |
TROPICAL DEPRESSION 1008 HPA AT 07N 119E WSW SLOWLY. 至少還是以熱低正式活到 1 月 1 日了。 |
