A decrease in average annual total cloud cover was observed from 1960-2009, based on data from 606 meteorological stations in China. Specifically, the cloud cover in 1980-2009 was 0.6% less than that in the period 1960-1970. In coastal areas of China south of the Yangtze River, a stable variation in total cloud cover was observed, however, a significant difference was observed in the spatial variability of low clouds. In the Sichuan Basin during 1960-2009 the low-cloud cover has decreased by approximately 4.0% every decade since 1960. The situation is different in other regions of China. For example, south of the Yangtze River, east of Northeast China, and west of Xinjiang to the northern of Qinghai Tibetan Platean, low-cloud cover increases about 4.8% on average every decade since 1960.
