利用喀什地区各气象站观测资料、区域自动站气象观测资料和ECWMF （2.5o×2.5o）、T639（1o×1o）细网格资料、喀什新一代多普勒雷达资料，对2013年6月18日发生在新疆喀什地区境内的一次罕见的强冰雹天气从天气形势、中尺度系统、水汽条件、雷达回波特征等方面进行了综合分析。分析显示，此次冰雹天气是在有利的大尺度环流背景下产生的，冰雹出现前，雹区附近低层到地面存在中尺度切变线、涌线和地面中低压等多个中尺度系统；水汽在中低层集中，并不断向冰雹区输送；雹区附近强烈的辐合上升运动为冰雹的出现提供了水汽和动力条件；11个对南疆冰雹预警具有较好指示意义的探空物理量参数均有利于大气不稳定能量的聚积和爆发；雷达回波上，超级单体强度越强、维持时间越长，造成的冰雹持续时间更长、直径更大、雹灾更重。

By using the routine data, ECWMF data, T639 data, the new generation of doppler radar data of Kashi and the regional meteorological automatism station data in Xinjiang, one strong hail weather in Kashi area on June 18th,2013 was analyzed.The results showed that:the hail was happened in the favorable large-scale circulation background and has many mesoscale systems which include the mesoscale shear line, pressure jump line, mesoscale low near the hail area before it happened. The water vapor was concentrated and transported on the low level and the strong convergence ascending motion bring humidity and dynamic conditions for the hail.There also has some physical parameters helped the accumulation and the outbreak of the instability energy.The analysis of this strong hail weather can help us improve the thinking for the short-term forecast and the early warning of the hail in southern areas of Xinjiang.
