对流层上层和平流层下层(UTLS)的范围约为520 km。UTLS中大气成分的分布和变化对于理解气候变化至关重要。在该地区，臭氧是一种有效的温室气体，水蒸气、卷云和气溶胶通过主动调节太阳辐射和长波辐射，对天气和气候变化产生重要的辐射强迫。强对流云中的飞机排放和闪电产生大量的NO_x，产生大量的NO_x，这使得UTLS中的大气成分分布和变化对理解气候变化至关重要。本文介绍了平流层对流层交换（STE）研究中的科学问题和研究方法，总结了相关领域特别是近年来国内工作的一些进展，并对一些关键问题和展望进行了展望。 STE。
The range of upper troposphere and lower stratosphere(UTLS) is about 520 km.The distribution and change of atmospheric constituents in UTLS are crucial in understanding the climate change.In this region,ozone is an effective greenhouse gas,and water vapor,cirrus cloud and aerosol have important radiative forcing on the weather and climate variation by actively adjusting the solar radiation and long-wave radiation.Aircraft emission and lightning in the strong convection clouds producing considerable NO_x take place in UTLS,which greatly impact the structure of atmospheric constituents in UTLS and upper and lower layers.In this paper,the scientific issues and research methods in the study of stratospheretroposphere exchange(STE) are introduced,and some advances in related fields,especially domestic works in recent years,are summarized.Some key issues and prospects are also discussed.Finally,some expected researches are emphasized in the study of UTLS over the Tibetan Plateau,because the STE processes in this region not only have some significant regional features,but also play potentially an important role in the global STE.
