湖北省春、夏季暴雨中尺度对流回波系统初探

A PRELIMINARY STUDY OF THE CONVECTIVE ECHO SYSTEM IN SPRINGSUMMER MESOSCALE HEAVY RAIN OCCURRENCES IN Hubei PROVINCE

摘要:

根据1987-1989年武汉和宜昌数字化雷达回波资料,将湖北省春、夏季暴雨初步分为中-α尺度暴雨云团、冷锋暴雨、暖区对流降水带、登陆台风暴雨、复合(或超级)单体等五类。描述了各类暴雨的中尺度结构及其变化的一些特点。

Abstract:

In the light of Wuhan and Yichang digitized radar echo data obtained during 1987-1989, the heavy rain occurrences in Hubei province in spring and summer are classified iuto five types, namely, meso-α scale heavy rain cloud cluster, cold front heavy rain, convective rain band in warm areas, landing typhoon, and multicell or snpercell. some eharacteristics of theirmesoscale structures and evolution. processes are described in this study.
