| 摘 要： | 利用Micaps系统下常规资料、云图资料和数值预报产品、物理量场，对2009年5月9-10日发生在山西省东南部的一次暴雨过程进行综合分析。结果表明：500hPa的西风槽东移加深为暴雨的产生提供了大尺度环流背景，低层的切变是暴雨产生的主要影响系统，散度、垂直速度、能量场等物理量的垂直分布有利于暴雨产生．暴雨发生在切变线前部，中尺度系统是强降水形成的直接影响系统。

| Abstract: | In this paper, using general information, satellite data and numerical prediction products, physical quantity field of Micaps system, the authors analyzed a rainstorm process in southeast of Shanxi province on ninth-tenth, May, 2009. The results indicated that eastward of 500 hPa westerly trough provide large scale circulation for rainstorm. Lower shear was main influencing system arised by rainstorm. Vertical distribution of divergence, vertical velocity and energy field was in favour of the formation of a... |
