摘    要:通过对福建中北部35个站1994~2001年97次暴雨过程的环流背景、影响系统等进行分析,将天气类型分为冷式切变(或槽)影响型、西南气流影响型、副高型(Ⅰ~Ⅱ型),归纳总结了各天气型的雷达回波源地、加强区域、路径、演变及降水特征,建立了天气图等常规资料与雷达回波资料相结合的闽中北短时暴雨3种概念模型。Ⅰ、Ⅱ型的降水强度总体相差不很大,有西南风急流比没有时降水强,Ⅱ型尤其明显,Ⅲ型降水强度最弱、持续时间最短。

Abstract:An analysis was made of the circulation background and influencing weather systems of 94 short-range heavy rainfall events from 1994 to 2001 in the northern and central Fujian Province,and the synoptic patterns were divided into three types: cold shear (or trough), southwest flow and Subtropical High. The source and enhancing areas and path, evolution and precipitation features of radar echoes under various weather patterns are summarized. Three conceptive models of short-range heavy rains for the northern and central Fujian Province were established,aiming to improve short-range prediction and to combine synoptic maps with radar echoes.
Keywords:short-range heavy rain  synoptic pattern  radar echo  conceptive model
