摘要 利用Cloudsat和CALIPSO卫星资料统计分析了8、9月沈阳地区云系的垂直结构特征。结果表明,8月下旬和9月上旬沈阳地区出现的云系以单层云为主,所占比例分别是72.43%和63.5%;双层云所占比例分别是27.1%和28.62%;其余为三层云。8月下旬,低云的云底高度在0.5~1.5 km之间,中云在3.8~4.0 km之间,高云在8~9 km之间;9月上旬,低云的云底高度在1.0~1.5 km之间,中云之上如果没有其他云层,其云底高度在5.0 km以上,如果之上还有云层,则其云底高度在3.2~4.5 km之间,高云之下如果没有其他云层,云底高度在7.4~7.8 km之间,如果之下还有其他云层,其云底高度在9 km以上。建立的8、9月沈阳地区作业云系垂直结构特征模型能够为人工影响作业方案的设计提供有效参考。 The characteristics of the cloud vertical structure in Shenyang region was analyzed using Cloudsat and CALIPSO satellite data during August and September in order to provide the climate background information of weather modification. The results showthat: From late August to early September,clouds appeared in Shenyang region was mainly in the single-layer clouds,and the proportion respectively was 72. 43% and 63. 5%. The double layer clouds proportion was 27. 1% and 28. 62%,and the remainder was three layer clouds. In late August,the height of cloud base for lowclouds was among 0. 5 ~ 1. 5 km,the middle clouds was among 3. 8 ~ 4. 0km and the high clouds was among 8 ~ 9 km. In early September,the lowclouds cloud base height was between1. 0 ~ 1. 5 km. Cloud base height of middle clouds was more than 5. 0 km if there was no cloud on the top,else the cloud base height was among 3. 2 ~ 4. 5 km. Cloud base height of high clouds was among 7. 4 ~ 7. 8 km if there was no cloud under the cloud,else the cloud base height was more than 9 km. Finally,a vertical structure model of the operating clouds was created and the reference program was designed in order to provide a reference for weather modification operation.
