摘　　要：利用常规观测资料和NCEP1°×1°再分析资料,对2007—2016年6—8月8次副高影响下的区域性暴雨天气过程,采用统计学、天气学方法和合成技术进行分析,结果表明:在副高东退、引导高空槽东移的大尺度背景条件下,配合低层辐合系统是造成遵义市区域性暴雨过程的天气系统;暴雨过程有3种类型:低涡槽型、高空槽气旋旋转型和高空槽低涡切变型; 3种类型的天气系统进行合成分析后,找出了暴雨落区与高空系统、物理量配置之间的关系。By using conventional observation data and NCEP 1°×1° reanalysis data, eight regional rainstorms took place in the summer from 2007 to 2016 under the influence of subtropical high. Statistical, weather and synthetic methods were used to analyze .The results indicate that regional rainstorms were caused by high-level trough movement and the lower system. There were three types after classification: Low vortex groove type, high-level trough rotary type and high-level trough low vortex shear type. A synthetic analysis was performed for each type of high altitude system. The relationship between rainstorm zone and altitude system and physical quantity configuration was found out.
