摘　　要：利用高空和地面实时资料及T213数值预报产品资料,对2005年8月12日凉城地区一次强降水过程的环流背景进行了诊断分析,结果表明:此次强降水过程主要是西太平洋副高西伸与华北脊叠加作用完成了水汽的充沛输送,是此次天气过程中的重要条件,配合地面低压的强烈发展而产生了一次强降水天气过程;具有降水强度大、对流性明显等特点。Using high altitude, surface timely date and T213 numerical forecast production, the circulation background of a severe precipitation process was diagnostically analyzed on August 12, 2005 in Liangcheng district. The results showed that this precipitation process resulted from the superposition of west pacific subtropical high pressure and north china ridge, and transported enough water vapour, it was important condition of this precipitation process, a severe precipitation synoptic process was formed cooperating with severe development of surface low pressure, and its characteristics was great precipitation intensity and obvious convection.
