摘要:

大气上对流层与下平流层区域是对流层与平流层之间的过渡区域,热带对流层顶确定了全球整个平流层的化学边界条件,该区域大气的垂直结构及变化对于平流层—对流层交换和上对流层/下平流层大气成分收支有重要影响;该区域也是大气动力、热力和大气成分结构发生巨大转换的区域,辐射过程、多尺度动力学过程、化学过程和微物理学过程等都起着同样重要的作用,对流层顶变化也是人类活动引起气候变化的一个敏感指示因子,因此关于对流层顶的研究(尤其是其精细结构和过程)重新唤起了人们的关注。针对对流层顶的各种定义(包括热力学、动力学和化学成分)以及它们相互之间的关系、对流层顶是一个面还是层以及对流层与平流层之间的转换特征、对流层顶强逆温层的特征及形成原因等基本科学问题,回顾了近年来的一些重要研究进展。

Abstract:

     The issues in the atmospheric tropopause structure and its variation are crucial in the study of stratosphere-troposphere exchange and the balance of atmospheric tracers in the upper troposphere and lower stratosphere, and the change of global tropopause height is a significant indicator in the climate change caused by human activity. Therefore, the study of tropopause, particularly the finer structure and key processes, arouses the attention in the world. In this paper, recent advances in the study of a few basic scientific problems on the definitions of tropopause (such as thermal, dynamical, and chemical definitions, and relationships among them), tropopause being a interface or a layer and the role of mixing in the transition between troposphere and stratosphere, and the distribution feature of tropopause inversion layer and its formation, are reviewed, and current problems among them are given some comments.

Key words: Tropopause    Upper troposphere and lower stratosphere    Finer structure
