Abstract: The diabatic heating and kinetic energy budget over Oinghai-Xizang Plateau are estimated,based on the data collected by the Qinghai-Xizang Plateau Meteorological Science Experiment during the summer 1979.The results revealed that the energy budget over the Plateau have its peculiarity.During the summer,the Plateau atmpsphere is one of the important source region of the heating and kinetic energy in the Northern Hemisphere.It is indicated that the formation of the summer circulation over the Plateau is earlier than the seasonal transition of the East Asia general circulation.
