平流层突然变暖期间重力波在垂直耦合中的作用

Role of gravity waves in vertical coupling during sudden stratospheric warmings

Erdal Yiğit, Alexander S. Medvedev

摘要:

重力波主要产生于低层大气,在传播过程中可到达热层高度。本文综述了平流层突然变暖过程中重力波在垂直耦合中作用的研究进展。简要回顾了重力波效应的模拟方法,并介绍了该领域的最新进展。然后,概述了这些波对高层大气大气环流的影响。最后,在平流层突然变暖的背景下,讨论了重力波在低层和高层大气垂直耦合中的作用。

英文摘要:

Gravity waves are primarily generated in the lower atmosphere, and can reach thermospheric heights in the course of their propagation. This paper reviews the recent progress in understanding the role of gravity waves in vertical coupling during sudden stratospheric warmings. Modeling of gravity wave effects is briefly reviewed, and the recent developments in the field are presented. Then, the impact of these waves on the general circulation of the upper atmosphere is outlined. Finally, the role of gravity waves in vertical coupling between the lower and the upper atmosphere is discussed in the context of sudden stratospheric warmings.
