Abstract
按照历史发展, 回顾了从无耗无风背景下线性化的大气潮汐方程组出发得到一个二维定态变量可分离的基本偏微分方程及其全球Hough函数波模解的经典理论; 介绍了主要由Forbes和Hagan发展起来的在真实有耗有风背景下线性化的本质上仍是二维定态, 但纬度和高度变量不可分离的现代数值模式GSWM; 概述了近年来针对中高层大气的GCM (例如TIME-GCM, MUAM, CMAM和WACCM) 来研究潮汐非线性及非迁移潮汐等的发展趋势. 在融合理解的基础上对各模式的特点和模式间的差异进行了适当分析, 从中可以看出,半个世纪以来人们在从第一原理出发试图揭示全球大气潮汐的真实结构特征和长短期变化机制等方面进行了持续的努力, 这种努力又是与从利用地基雷达到卫星搭载仪器观测大气(特别是MLT区域的风场和温度场)的发展密不可分的.
