摘要
深对流能够向上对流层—下平流层(UTLS)输送大量水汽和污染物,对对流层顶的辐射平衡、平流层的臭氧恢复以及全球气候变化都有着重要的影响。近年来,一系列重要的观测事实发现,青藏高原和亚洲季风区是对流层向平流层物质输送(TST)的重要窗口。本文介绍了近年来取得的一些主要进展和成果,包括:(1)通过卫星观测在青藏高原—亚洲季风区上空发现水汽、气溶胶的极大值区和臭氧的极小值区;(2)深对流活动的主要观测途径和通过卫星观测识别深对流的方法;(3)青藏高原深对流向平流层物质输送的物理过程;(4)青藏高原深对流与亚洲季风区、热带海洋地区深对流的结构差异以及不同环境场对深对流物质输送过程的影响。
The material transport of deep convection in the upper troposphere–lower stratosphere has an important impact on the radiation balance of the tropopause,ozone restoration in the stratosphere,and global climate change.In recent years,a series of important observational facts has shown that the Tibetan Plateau and the Asian monsoon regions are important windows for tropospheric-to-stratospheric transport.This article introduces some recent major progress and achievements and includes four points:First,the maximum value area of water vapor and aerosol and the minimum value area of ozone were found by satellites over the Tibetan Plateau and the Asian monsoon region;second,the main observation methods of deep convection activities and the identification method of satellite observations on deep convection were discussed;third,the physical process of deep convection material transport to the stratosphere over the Tibetan Plateau was established;finally,a comparison was made between the structural differences in the deep convections in the Tibetan Plateau,Asian monsoon region,and tropical ocean regions as well as the impact of differences in environmental fields on the process of deep convection material transport.
