平流层－对流层相互作用的多尺度过程特征及其与天气气候关系—研究进展

在过去5年中，在国家自然科学基金委员会和中国科学院的项目支持下，针对以大气上下层相互作用中的多时空尺度过程特征及其与天气气候的关系为主要关注内容，开展了几个方面的研究。本文介绍其中的一些主要进展与结果，包括:(1)平流层臭氧的探测与分析研究；(2)平流层－对流层质量交换(STME)与对流层顶特征研究；(3)中层大气多尺度波动特征研究；(4)大气辐射传输和中层大气卫星临边遥感新方法研究。

Advances in Researches on the Characteristics of Multi-Scale Processes of Interactions between the Stratosphere and the Troposphere and Its Relations with Weather and Climate

In the past five years,funded by the National Natural Science Foundation of China and the Chinese Academy of Sciences,the investigations of the characteristics of the multi-scale processes and the relationship between the processes and weather and climate were conducted in the context regarding the interactions between atmospheric layers.This paper summaries the major results and the advancements in the key research aspects:1)sounding and analyzing the stratospheric ozone,2)estimating the mass exchange between the stratosphere and the troposphere(STME)and the features of the tropopause,3)investigating the characteristics of the multi-scale atmospheric waves in the middle atmosphere,and 4)developing new schemes for the calculation of radiative transfer and the retrieval of middle atmospheric parameters using satellite limb soundings.
