| 摘 要： | 利用常规观测资料、T213资料、FY-2C卫星资料和多普勒雷达资料等,对0604号台风“碧利斯“进行了综合研究,并与历史上相似路径的台风进行了对比分析.分析结果表明,“碧利斯“造成的暴雨出现在江西中南部,与历史上进入赣南的热带气旋一般特点相一致;“碧利斯“路径与副高的位置和演变有关;“碧利斯“造成的江西暴雨落区,与辐合上升运动中心及高层辐散中心对应较好,并与台风不对称环流、地形、不稳定能量等因素有关;暴雨与湿位涡呈反位相相关,且在暴雨较强时相关性更好.

| Abstract: | We studied typhoon BILIS and compared it with typhoons with similar path in history using data of conventional observation,T213,FY-2C satellite and Doppler radar.The results indicate that: rainstorm caused by BILIS appeared in the middle and south Jiangxi,which conforms to similar typhoons in history entering Ganzhou.The path of BILIS is relation with the location and evolvement of subtropical high.The rainstorm area in Jiangxi caused by BILIS matches well with upward current and upper divergence and relates with asymmetry,terrain and instability.Rainstorm phase is the inverse of humidity potential vorticity,especially in severe rainstorm. |
