摘　　要：用Micaps实况、EC预告初始场资料、雷达资料及地面自动站资料,对2017年7月16—18日喀什地区局地短时强降水天气诊断分析。结果表明:西西伯利亚低槽底部短波槽分裂东移,中低空水汽通量较好,有水汽通量辐合区;强回波中心接地,有明显弱回波区,岳普湖站附近为明显辐合区,喀什有较强低空偏北急流,触发强对流天气。这些特征与短时强降水出现时次基本吻合。Using MICAPS,EC forecast initial field data,radar data and ground automatic station data to diagnose and analyze the local short-term heavy rainfall weather in Kashgar region from July 16 to 18,2017,the results show that:the short wave trough at the bottom of the West Siberian trough splits eastward,the water vapor flux in the middle and low air is better,and there is a convergence area of water vapor flux;the strong echo center is grounded,and there is an obvious weak echo area,yuepuhu station There is a strong low-level northerly jet in Kashgar,which triggers strong convective weather.These characteristics are basically consistent with the occurrence time of shortterm heavy rainfall.
