“凤凰”暴雨物理量场诊断分析

The physical mechanism diagnosis of rain storm"Fung-wong"

利用NCEP再分析资料,对0808号强台风"凤凰"暴雨过程进行了物理量诊断分析。主要通过研究与降水有关的大气物理量场的变化及分布,从台风暴雨的发生发展机制与涡度、散度、相对湿度及水汽通量等之间的关系入手,分析了"凤凰"暴雨产生的时期、区域及强度与大气物理量场之间的内在联系。

Based on the NCEP reanalysis data,the 0808 typhoon＂Fung-wong＂heavy rainfall is analysized.By studying the variation the precipitation-related meteorological factors,the vorticity,divergence,relative humidity and vapor flux related with precipitation are investigated,The mechanism of the 0808 strong typhoon ＂Fung-wong＂are diagnosed.
