摘　　要：利用南疆阿克苏新一代天气雷达CINRAD/CC的基本产品和导出产品,分析了阿克苏一次冰雹过程的环流背景、环境因子以及冰雹云多普勒天气雷达的回波特征,发现中等强度的垂直风切变和弱回波区是此次冰雹天气的重要特征,并得出垂直累积液态水含量、回波顶高和FY-2C定量产品的简明预报判据,为南疆地区冰雹的临近预报提供了依据。Echo characteristics, circulation background and environment variables during a hailstorm in Akesu were analyzed by using basic CINRAD/CC data and its production. It is shows that there is a medium-intensity vertical wind shear and a weak echo area in the hailstorm. Moreover, a simple identification for forecasting hailstorm weather related to the Vertically Integrated Liquid water content （VIL）, the top height of echo area and FY-2C products is obtained. It provides the basis for nowcasting of hailstorm in the South of Xinjiang.
