| 摘 要： | 利用ECWMF数值预报产品资料、逐日客观分析资料、常规观测资料以及高密度区域气象自动站降水资料和物理量资料,对2011年6月中、下旬发生在贵州西部地区的两场暴雨天气过程进行对比分析。结果表明:①两场暴雨的发生,中低层均有西南低涡沿切变线东南移和强盛的西南暖湿气流,第1场有高原槽,第2场既有高原槽又有南支槽等天气条件的有效合理配置,以及较强的垂直上升运动和充足的水汽、能量条件,为暴雨产生提供充分的条件。②区域气象自动站降水资料显示,中小尺度天气系统演变对强降水落区有很好的指示意义。③WRF模式较准确地模拟出降水落区、强度以及700 hPa上西南涡沿切变线移动趋势,对类似暴雨短时临近预报具有重要的指示意义。 |

| Abstract: | By using of objective analysis ECWMF data, conventional observation, the automatic weather station data and physical quantity, the rainstorm at night o,1 mid to late June 2011 in Western Guizhou~Province is analyzed. The results clearly show：（1）The two rainstorms had trough （or southern trough ）, southwest vortex, shear line, jet and deep water vapor and other weather conditions is effective and rational allocation of weather conditions. The two rainstorm of occurred, there is strong vertical motion, the abundant energy and water vapor over conditions on Western Guizhou, these conditions for the rainstorm provides a sufficient condition. （2）The regional data shows, au- tomatic stood on the small and medium - scale weather system of precipitation rain formation and strengthen played an important role, and for the short- term forecast has instructions near. （3）WRF model simulate precipitation rain formation, intensity -time forecast has and 700 hPa southwest vortex moving along the shear line trend, similar to the rainstorm short important significance |
