摘　　要：利用新疆阿克苏CINRAD/CC多普勒天气雷达的探测资料,在新疆气象局新一代天气雷达网络应用软件和CINRADPUP软件产品的基础上,分析研究了2003年11月5～7日发生在阿克苏地区的大降水天气,得出:此次天气的强度场、速度场、垂直剖面结构具有积层混合性降水回波与层状云降水回波的特征,低空偏东急流、暖平流中尺度系统和速度场分布对强降水的定时、定量、定点预报具有明确的指示意义。Base on CINRAD/CC data in Akesu area of xinjiang, the application software of CINRAD/CC network of Xinjiang Meteorological Bureau, and CINRAD PUP data, analyzed the heavy rain from 5 to 7 November of 2003 in Akesu area of xinjiang. The results indicate that the velocity and intensity field, and perpendicular section have the echo characteristics of the cumulonimbus and stratus. The measoscale systems of the east low- level jet and warm advection, and velocity field are obvious signals for forecasting heavy rain.
