摘　　要：利用望谟县区域自动站资料、Micaps常规资料、望谟县国家基本气象站资料，应用天气学原理和方法对2011年5月10日20：00—11日20：00发生在望谟县境内的暴雨过程进行综合分析。结果表明，西南低空急流、低层切变辐合是形成此次暴雨的直接影响系统；低空急流向县境内暴雨区提供了大量的水汽、能量和垂直上升运动，是此次暴雨过程的重要影响系统。Using the regional automatic weather station data of Wangmo County , conventional micaps information and the weather station da- ta of Wangmo County, a comprehensive analysis of torrential rain which happened in Wangmo County from 8p. m. on May 10,2011 to 8p. m. of the 11 th was carried out. The results showed that the low level jet of southwest and the lower shear convergence were the formation of having a direct effect on the rainstorm. The low level jet provided a lot of water vapor, energy and vertical upward motion for the Rainstorm area , which was an important influence sistem on the rainstorm
