中层大气重力波的研究

STUDIES ON GRAVITY WAVES IN THE MIDDLE ATMOSPHERE

中文摘要:

      中层大气(Middle Atmosphere)是近十多年来被广泛使用的一个新名词,它是指从对流层顶的10-16km到湍流层顶约100km之间的大气层,即中层大气由平流层、中间层加上热成层下部的一小部分组成.黄荣辉^[1]对中层大气的一般动力学、行星波动力学和赤道平流层波动及其与基本气流相互作用的近期研究作了评述.本文侧重综述中层大气内的重力波及其与基本气流的相互作用.

英文摘要:

      The recent advances in the studies on gravity waves in the middle atmosphere are reviewed. An introduction to the historical background on anomalous temperature distribution in the mesosphere leads to the following three aspects of gravity wave studies:(1) observations and analysis of gravity waves, (2) generations, propagations and gravity wave-mean flow interactions, (3) gravity waves breaking and its parameterization in general circulation models. Finally serveral issues for the future research are proposed.
