利用矢量锋生函数对一次暴雨过程的分析探讨

Analysis of A Storm Process by Vector Frontogenetic Function

对在江淮流域发生的一次暴雨过程观测资料计算矢量锋生函数,并用其对该过程进行了诊断分析,发现矢量锋生函数与江淮梅雨锋暴雨落区的发生移动有较好的对应关系,进而讨论了用矢量锋生函数作锋面强降雨天气预报的可能性。

The vector frontogenetic function is calculated by using the observed information on a storm process happened in Yangzi - Huanhe drainage area, based on which a diagnosis analysis of the storm process is made. The analysis reveals a close correlation between the vector frontogenetic function and the moving of storm falling area in Yangzi-Huanhe drainage area. Argumentation is carried out on the feasibility of forecasting the frontal raining weather by way of vector frontogenetic function.
