摘　　要：文章利用2013年内蒙古中部地区呼和浩特、东胜、临河、乌拉特中旗4个高空观测站的L波段探空秒数据,采用相对湿度阈值法,进行云垂直结构气候学特征分析以及降水云系的垂直结构分析。结果表明:呼和浩特地区平均云底高度为2680m,平均云顶高度为6433m,平均云厚为3753m。在全年中有60.2%的时间是无云天气;在有云时候,单层云约占24.1%;多层云中以双层云居多,约占总数的10.1%。云底高度低于2.5km、云层厚度在3.5km以上、云顶高度高于5.0km且连续无夹层是内蒙古中部地区降水云系的垂直结构特征。Climatological characteristics of cloud vertical structure and vertical structure characteristics of rain cloud were analysized,with relative humidity threshold value,base on L band sounding second data of Huhhot, Dongsheng, Linhe,Wulate.The results showed, average high of cloud base is 2680m,average high of cloud top is 6433m,average thick is 3753m.There is 60.2% days are no cloud; Single layer cloud accounted for 24.1%;double layer cloud accounted for 10.1% of the total. Vertical structure characteristics of rain cloud in the central part of Inner Mongolia are high of cloud base below 2.5km,thick is above,high of cloud top is more than 5.0km,and cloud is consecutive.
