1979年初夏青藏高原上空大气的非绝热加热和动能收支的特征

THE FEATURES OF THE DIABATIC HEATING AND THE KINETIC ENERGY BUDGET OVER THE QINGHAI-XIZANG PLATEAU DURING THE EARLY SUMMER 1979

摘要: 本文根据青藏高原气象科学实验期间的资料,计算了1979年5-8月青藏高原地区大气的非绝热加热和动能收支.其结果表明:青藏高原地区上空的能量收支有其明显的独特性,夏季青藏高原地区的大气是北半球重要的热源和能源区.并指出,青藏高原地区上空夏季型环流结构的建立要超前于东亚大气环流的季节性变化.

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.
