Abstract:

Using the new generation weather radar(CINRAD) data including echo intensity, velocity, composite reflectivity, hail index profile, storm tracing information, VIL and meso-cyclone 12 severe cnnvective weather events nccnrred in 2003 and 2004 in Ningxia were studied. According to image characteristics, radial velocity products were classified as 3 types, and were analyzed respectively form meso-scale SynOptlC pTlnClple.

摘要：

利用银川新一代天气雷达2003-2004年汛期监测到的12次强对流天气过程产品，主要包括:强度、速度、组合反射率、冰雹指数、风廓线、风暴追踪信息、垂直积分液态水含量、中尺度气旋等，特别是径向速度回波产品，根据产品图象特征，将其分为3类，分别从中尺度天气学原理等进行深入的综合分析，得出多普勒天气雷达的几种重要产品对强对流人y特别是冰雹天气的临近预报具有重要使用价值，同时与常规数字化天气雷达进行了对比分析。
