【Abstract】 Owing to the influence of the atmospheric circulation with the different time and space, and the function of the dynamic and heat of the Qinghai Xizang Plateau, it is formed the “cold trough”(low temperature trough) in winter and “Thermal backbone”(high temperature backbone) in the east of China. It is a very complex problem that the formation of the “cold trough” and “thermal backbone” is influenced by many factors. Among them, the dynamic and heat of the Qinghai Xizang Plateau are important factors. The formations of the “cold trough” and “thermal backbone” can influence the climate in east of China.更多还原
