摘　　要：2010年7月26日-31日山西省大部分县市出现持续高温晴热天气，高温范围大，持续时间长，多数县市最高气温达到或超过了7月历史极值；本文通过对持续高温天气的环流场特征、物理量场及常规气象要素分析，得出结论：中低层暖平流和下沉增温对高温天气的形成有增强作用，非绝热加热是高温天气形成的主要原因，少云、微风的气象条件则有利于高温天气的持续。Most counties and cities in Shanxi Province had sustained high temperature weather on July 26 to 2010. The high temperature range, long duration and the high temperature of a lot of counties and cities reached or exceeded historical extremes value. The circulations characteristics, physical field and conventional meteorological elements of continuous high temperature weather were analyzed. The results showed that middle and low level warm advection and sinking enhanced the formation of the high temperature.
