摘　　要：利用阿克苏CINRAD/CC的基本产品、敏视达软件的导出产品及新疆气象局新一代天气雷达网络应用软件生成的垂直剖面资料,综合分析了2005年7月15日夜间发生在阿克苏市西南部的一次雹暴过程,发现该多单体雹暴产生于一个中尺度对流系统中,加之有利的环流背景、环境因子和回波强度场(弱回波区)、径向速度场的三维空间配置,使风暴东移南压过程中发展为多单体风暴产生冰雹。同时得出了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。Analyzes synthetically a hailstorm process occurred at nighttime 15 July 2005 in the southwest of Akesu of Xinjiang,by the means of CINRAD/CC's basic product,Metstar software's outputting product,and vertical section product data that is led out by the application software of CINRAD/CC network of Xinjiang Meteorological Bureau.It has found that the multicell storm was born in a mesoscale convective system.With the advantage of the atmospheric circulation,environment factors,and three-dimensional conditions of echo intensity field(weak echo region)and radial velocity field,the storm developed into multicell storm created hail in the process of storm moving to the southeast,meanwhile the forecasting criterion of the Metstar outputting product(VIL,ET)and FY-2C quantitative product were gained.
