摘要
利用常规气象资料、数值预报产品、物理量场以及雷达回波资料，对2007年8月26日-27日发生在长治地区的一次大暴雨过程进行综合分析。结果表明：此次大暴雨过程由3次不同的中小尺度降水系统导致产生；大暴雨发生在中层5880gpm和5920gpm之间，低层切变线偏南气流一侧，高空急流右侧；东南气流为这次暴雨提供了充分的水汽，大暴雨发生在强烈上升运动及层结不稳定中心。
Using the data of NWP and Doppler weather radar echoes and routine meteorological data, the heavy rainstorm weather process occurred on Jul 13 2006 is analyzed. The results show： This weather process is led by three different meso - scale and microscale precipitation systems. The heavy rainstorm occurs in the surface area which corresponding is between 5880gpm and 5920gpm over middle level of troposphere, at the side of south airflow of shear line over low level and the right side of jet over high level. The southeast airflow provides abundant water vapor and the heavy rainstorm occurs in the center area of ascending movement and unstable stratification.
