10月初滇西秋季连阴雨过程分析

运用NCEP在分析资料分析滇西地区10月6-10日秋季严重连阴雨天气期间环流形势及水汽输送特征,结果表明:本次连阴雨天气期间由于副高位置较偏东,势力较弱,孟湾南支槽缓慢东移,水汽通量矢量场显示本次过程以孟湾水汽输送为主,副高外围的水汽输不明显。

At the beginning of October in Western Yunnan Autumn LianYinYu Process Analysis

Using the NCEP on the analysis of the data analysis in western yunnan on October - 10 autumn serious during the pre-summer rainy periodscirculation patterns and characteristics of water vapor transport, and the results show that: the subtropical high position during the pre-summer rainyperiods due to a partial east, power is weak, the MengWan southern trough slowly towards the east, the steam throughput vector field shows that thisprocess to MengWan water vapor transport is given priority to, the subtropical high peripheral water vapor transport is not obvious.
