Abstract: In this paper, the vertical velocity ω, the large-scale apparent heat source Q1 the moisture sink Q2, the atmospheric energy transformation are computed daily for the subareas over the Oinghai-Xizang plateau during summer 1979. The western subarea is bounded by Lhasa, Nagqa, Shuanghu,Gerze and Zhongba stations(fig. 1) The last three stations were established for the purpose of the Oinghai-Xizang Plateau Meteorology Experiment of summer 1979.The eastern subarea is bounded by Lasa, Nagqa, Yushu, Ganzi and Deqing stations. Moreover, a spectral analysis was made for the above mentioned elements. Fig.5 shows computed results of the cycle of energy tramsformation averaged for the whole summer.
