摘　　要：文章利用常规气象观测资料,配合闪电和卫星云图等监测资料对2013年6月30日鄂尔多斯市东胜区出现的冰雹、雷雨等强对流天气过程进行分析,结果表明:此次强对流天气是由高空冷涡底部西风小槽和南支系统西南气流配合地面倒槽影响造成的;强对流天气发生之前,自动气象站分析要素有明显变化,温度露点差≤2℃,气压陡升,总温度下降剧烈,同时伴随偏南风。Based on the data of conventional meteorological observation, lightning monitoring and cloud atlas, the severe convective weather processes such as hail, thunderstorm in Dongsheng District of Erdos were analyzed on 30 June, 2013. The results showed that the severe convection weather is attributed to the interaction of westerly small groove in bottom of the upper cold vortex, southwesterly airstream in front of the southern branch system and inverted trough on the ground. Before the occurrence of the severe convective weather, the observation elements of automatic weather station obviously changed, the depression of dew point was less than or equal to 2℃ , the pressure suddenly increased,and the temperature dropped dramatically accompanied by south wind.
