Abstract:
Based on the data of heating resource, and the rainfall in Sichuan Province and Chongqing City, the relationship between the surface heating fields over the Plateau and the precipitation in Sichuan basin during summer is analyzed. The results show that (1) There are obvious correlations between the surface heating over the Qinghai Xizang Plateau and the precipitation in the Sichuan basin during summer. (2) The anomaly of the surface heating fields over the Plateau, which is forced by the anomaly of 500hPa circulation field over East Asia is able to affect the rainfall in the Sichuan basin during summer.
