摘　　要：利用自动气象站资料、Micaps常规资料和T639资料等气象资料,通过天气学和天气动力诊断分析方法,对2016年6月23-24日周口暴雨过程进行了综合分析。结果表明:高空槽配合低涡切变线和低空急流是这次暴雨形成的主要环流背景;同时地面冷锋的作用,加上有利的动力条件支撑此次降水过程;充足的水汽有利于暴雨的发生。Based on the automatic weather station data,MICAPS routine data and T639 data,the rainstorm process in Zhoukou from June 23 to 24,2016 was comprehensively analyzed by synoptic and synoptic dynamic diagnostic analysis methods.The results show that the main circulation background of the rainstorm is the high trough with low vortex shear line and low-level jet;at the same time,the surface cold front and favorable dynamic conditions support the precipitation process;sufficient water vapor is conducive to the occurrence of the rainstorm.
