摘　　要： 利用T213数值产品及常规气象资料,对2002年7月21-24日及11月13-15日两场发生在湖北省内大面积连续性暴雨天气过程进行了综合诊断分析,揭示了发生连续性暴雨天气的环流形势、影响系统以及产生暴雨天气的热力条件和动力条件,发现了产生暴雨的一些物理量及结构的特征值并对其予以剖析,加深了对暴雨发生机制的认识,得出了暴雨落区、落点与各要素之间的关系,找出了两场不同季节暴雨过程的异同点,同时对新数值预报产品的释用做尝试性的分析,为今后精细化预报提供了启示和参考。 By using the numerical products of 7213, and the conventional meteorological data, the continuous rainstorms that one from Jul. 21st to 24th and the other from Nov. 13rd to 15th in Hubei province were diagnosed and analyzed. It discovered circulation pattern, influential system for continuous rainstorms, the thermal and dynamical conditions for heavy rains, discovered some physical factors and structure's characterisitic values which brought for ward the rainstorm, made us deeply understand the system of rainstorm generation, and the relationship between the falling areas/ points of the rainstorm and individual elements, pointed out the difference and resemblance between these two rainstorms, tried to analyze the appliance of the numerical forecast products, offered the revelation and reference for the forecast in the future.
