Abstract

Based on the CloudSat 2B-CLDCLASS and 2B-CWC-RO data from December 2011 to November 2013, the distribution of cloud amounts and cloud water path (CWP) for single layer and multi-layer respectively for different cloud types over China and its neighborhood in the daytime were analyzed. Also the researches on the seasonal variation of the cloud water path over this area and how the macroscale circulation affects the variation were performed. The results show that the annual mean cloud amounts and CWP of single layer are in general more than the cloud overlapping's over this area. The 30°N is a clear north/south boundary for cloud amounts and CWP, which are relatively high in the north. The CWP of this area is greatly influenced by macro scale circulation,water vapor condition and terrain, and shows a feature that the content of the hydrometeors in summer is more than that in winter. Besides, the distribution of CWP is affected by the seasonal variation of the Westerlies substantially.

Key words： CloudSat; Single layer cloud; Multi-layer cloud; Cloud water path
