南海及周边地区云量分布及低云量与南海海温的关系
Distribution of the cloud amount and correlation between low cloud and the temperature over the South China Sea
摘要
Abstract
Using the International Satellite Cloud Climatology Project (ISCCP) monthly climate dataset, the distributions of the cloud amount over the South China Sea (SCS) and its neighborhood is studied, and the correlation between the low cloud and the temperature over SCS is further researched. The results show that: (1) There is remarkable seasonal feature of the distribution of total cloud amount. (2) The low cloud amount primarily distributes in SCS, the middle cloud amount primarily distributes in the region of south China, and the high cloud amount primarily distributes in the equatorial region. (3) The low cloud is influenced by SST over the SCS. The middle and high cloud are correlated to the strong convection. The low cloud distributes in the area of SST gradient of the warm sea region which lies in the south of the cold water center. The distribution of high value area of low cloud amount is consistent with the SST gradient. (4) The location of high-value center of low cloud amount is basically consistent with both sides of horizontal surface tempeature gradient. Forced by the western boundary, the warm water rises to the sea surface layer and leads to convergence, it is conducive to the formation of low cloud.关键词
