| 摘 要： | 对两架次飞行个例的DMT资料进行分析，发现山西春季层状云降水系统存在水平不均匀性。2010年4月20日的个例由高卷云、降水性高层云和非降水性高层云组成，高卷云与高层云之间千层较厚不利于形成降水。4月21日的个例由降水性高层云组成，云滴浓度随高度增加减小。对高卷云、非降水性高层云和降水性高层云的宏微观特征进行对比分析。云的垂直厚度越大，云底高度越低，云厚和过冷云层厚度越大，越有利于降水的产生。对这两次个例的云中可播性进行判别，发现存在可播区，无强可播区。

| Abstract: | It is found the heterogeneity of spring stratiform precipitation system in Shanxi by analysis of two times DMT data. There are high cirrus clouds, precipitation altostratus and non-precipitatlon high-level cloud in April 21, 2010. The dry layer between high cirrus and altostratus is thick. It is not conductive to precipitation. It is high level precipitation cloud in the case in April 21 and the cloud droplet concentration decreases with increasing altitude. |
