滇西北高原冰雹、短时强降水的多普勒雷达回波特征比较

Contrastive Analysis of Doppler-Radar Products on Hail and Short-time Severe Rainfall on Northwest Yunnan Plateau

摘要: 选取位于滇西北高原丽江市2006—2009年出现的4次冰雹天气过程和4次短时强降水过程,分析冰雹和短时强降水两类强对流天气的多普勒雷达回波特征。结果表明:冰雹云回波强中心值、强回波核(45～65 dBz回波)高度均高于短时强降水回波,

Abstract: Doppler-radar echo characteristics of hail and short-time heavy rainfall were analyzed using 4 selected hail events and 4 selected short-time severe rainfall events occurred in Lijiang on northwest Yunnan plateau
