| 摘 要： | 利用T213数值预报产品资料、常规观测资料及雷达回波资料对2005年7月2日02—09时泰山一次突发性强降水过程进行综合诊断分析，揭示了强降水过程的环流形势、影响系统以及产生强降水的热力条件及动力条件，发现了对强降水预报有意义的指标。分析表明：切变线辐合在触发本次强降水产生中起了关键作用，次级环流的形成促进了强降水的加强和发展，地形强迫抬升对于强降水的加强与分布起到了重要作用，θse高能区与强降水的产生具有显著的对应关系，对于强降水预报有一定指示意义。

| Abstract: | Based on the numerical products of T213, the conventional meteorological data and the echo data from radar, one abrupt heavy rainstorm over Mountain Tai from 02 to 09＇clock on July 2 in 2005 was generally diagnosed and analyzed. The results show： Convergence of shearing line plays a key role in triggering the occurrence of heavy rainstorm. The secondary circulation accelerates the development and strengthener of the heavy rainstorm,and rising airflow forced by topography plays an important role in rainstorm distribution and strengthen. θse has a significant connection with heavy rainstorm and can be a forecast index. |
