朔州市2010年秋季连阴雨天气过程特点及其对比分析

本文对2010年9月15日～21日出现在朔州市的一次连阴雨天气过程进行了详细深入的分析,从天气形势、物理量场、卫星产品等多方面的资料总结了此类过程预报的着眼点及分析思路,以期为中短期连阴雨预报提供理论依据.分析结果表明：连阴雨天气主要发生在冷暖气流频繁交汇的有利大尺度环流天气背景下,其中西风大槽的稳定发展、低层倒槽或西南涡发展维持,中低层的切变和辐合及副高势力的维持为连阴雨过程能量的积累及持续提供了极为有利的环流条件.

Characteristics and Comparative Analysis of a Persistent Rainy Process in Autumn of 2010 in Shuozhou

In this paper,a persistent rainy process from September 15 to 21,2010 is synthetically analyzed in several aspects,such as the synoptic situation,physical quantity field,satellite products,etc in Shuozhou in Shanxi Province.These ideas,including the notion and the emphasis of the forecasting,have been offered to guide mid-short-range forecasting of persistent rainy processes.The results show that,such as all these circulation background are favorable to the energy accumulation and sustaining of the persistent rainy process.
