摘　　要：利用气象探空资料,采用信息数字化的溃变结构图(V-3θ)法分析多个个例的云垂直结构,发现此方法能判定晴空和云区及其云层的位置,清晰分辨出云顶、云底及多层云、云夹层等结构。并将得到的分析结果与相对湿度阈值法判定的进行对比分析,结合实况发现一致性较好,验证了V-3θ结构图法判断云的垂直结构具有可行性,具有实际应用价值。This paper analyzed many clouds＇ vertical structure of meteorological sounding data by using the method of V-30 structure diagram of information digitization, and found that this method can distinguish clear sky, the clouds location, cloud-base height, cloud-top height, cloud thickness and multilayer cloud, etc. Compared the results with the that of by using relative humidity threshold method, to find they are well consistent, which proves that it is feasi- ble to distinguish clouds＇ vertical structure by using the method of V-30 structure diagram and has practical value.
