| 摘 要： | 利用中尺度模式MM5的部分产品，采用二元法，对2003年6月29-30日淮河流域上游暴雨天气过程中的条件性对称不稳定（CSI）进行了诊断分析，结果表明：此次过程中CSI区出现在对流层中上层，CSI区与对流稳定性大气层结条件下的强降水天气有很好的对应关系；利用MM5输出产品对物理量进行诊断分析，能够较好地解释局地强降水出现的物理机制。

| Abstract: | By using binary principle with the product of mesoscale model MM5, We diagnose the CSI in the rainstorm on Jun 29, 2003.Evidence suggests that CSI areas appear above the troposphere middle level in this rainstorm, and there were good relationships between the CSI areas and the strong precipitation under the condition of convective stability atmosphere; The diagnosis by using the product of MM5 can explain the physical mechanistic of local strong precipitation more correctly. |
