摘　　要：通过对新疆39a冰雹天气资料的普查,得到76次系统性冰雹天气过程和1279次局地冰雹天气过程,局地冰雹天气的发生远远多于系统性冰雹天气。冰雹天气过程与地形密切相关,主要发生在山区。冰雹天气以1天为主,多发生于夏季,系统性冰雹天气均由中尺度高压造成。Investigated 39 years hail weather data in Xinjiang , gained 76 systematic hail and 1279 local hail weather processes, the local hail was very considerably more than systematic hail. Hail weather processes were closely related to topography, mainly occurred in mountainous area. Hail weather was mostly during 1 day ,major in summer. Systematic hail weather was caused by mesoscale high pressure.
