摘要: 本文把青藏高原分成东西两个区,各区取5个站组成一个5边形,研究该两区1979年夏季的垂直运动、大气总加热、凝结加热、各种大气能量转换和输送、不均匀非绝热加热的特性,特别是其垂直分布和谱密度和交叉谱特性.其结果见第5节中结论.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.
