两个造成大风影响的热带气旋特征分析

应用NCEP/NCAR再分析资料,对造成玉林市持续长时间大风的0307号和8517号热带气旋(TC)的特点和大尺度环境特征进行对比分析,结果表明:0307号TC自身强度强,移速快;而8517号TC则移速缓慢,登陆后转向,TC中心在玉林市逗留时间长。两个TC登陆前后的大尺度环境特征不同造成其强度和运动特点的不同。

Characteristic Analysis For The Two Tropical Cyclone Causing The Gale Influence

This paper conducts the compared analysis on 0307 and the 8517th tropical cyclones(TC) the characteristic and the large-scale environment characteristic causing the lasting gale in Yulin city by using the NCEP/NCAR re-analyzing data.This paper conducts the compared analysis on the characteristic and the large-scale environment characteristic of 0307th and the 8517th tropical cyclones(TC) causing the lasting gale in Yulin city by using the NCEP/NCAR re-analyzing data.The result indicates that 0307 TC itself is intensive and moves fast,But 8517 TC moves slow,and changes its direction after landing,the TC center stays longer in the city.The difference of the large-scale environment characteristic of the two TC leads to their intensity and the movement characteristic differently.
