摘要
2003年1月4～5日云南发生的罕见的冬季暴雨是一次西风带大尺度斜压系统发展过程.利用T213模式计算的物理量场对暴雨过程进行了天气动力学诊断分析发现:暴雨发生机制可以用准地转运动理论得以很好地解释,为今后云南冬半年暴雨预报提供一些新的启示和参考依据.
An abriormal winter heavy rainfall event in the low-latitude plateau during Jan. 4--5 2003 was caused by a westerly macro-scale baroclinic system. Based on the physical field produced by T213 model, the synoptic diagnostic analysis of the event heavy is made. The result shows that the mechanism caused the heavy rainfall can be well explained by quasi-geotropic motion theory.
