摘　　要：对近几年来武汉雷达所观测的典型低涡、梅雨锋暴雨天气过程进行了多普勒雷达观测分析,总结了β中尺度暴雨回波系统的基本特征和强降水与诸多因素的关系。分析指出,在短时预报业务中,暴雨回波的识别和预警关键是从整体上要抓住β中尺度暴雨回波系统发生发展的特征,而不是孤立地研究一个对流单体的演变。This paper consists of the analysis of typical vortex and Mei-yu front rainstorm echo observed by Wuhan Doppler radar in recent years and the conclusion of the echo basic characters of meso-β rainstorm system as well as the correlations of heavy rain to several factors. The key point to identify and warn rainstorm is to pay more attention to the meso-β system features of rainfall echo entirely from system genesis to development, rather than to research one convective cell＇s evolution separately.
