| 摘 要： | 本文利用常规探测资料，对造成忻州市2011年7月2日和29日两次强降水天气过程的主要影响系统和物理量场特征进行了对比分析。结果表明，两次过程虽然高空都存在西风槽，但主要影响系统不同，低层切变线性质不同，低空急流强度不同；物理量场特征存在明显差异，导致两次降水过程的降水强度、强降水落区、范围都不相同。

| Abstract: | Based on the meteorological the physical field characteristics of two heavy although there is the west trough in high altitu sounding precipita de of two line is different and low lever jet strength is different. data, the comparing and analysis of the influence system and tion in July 2 and 29, 2011 were done. The results show that processes, main influence system is different. Low level shear Physical field characteristics are significantly different. So those resulted in the difference of the rainfall intensity, precipitation area and precipitation range |
