[0002] UTLS ozone has an important impact on global climate change, and directly or indirectly changes the thermal structure of the atmosphere, affecting human health and ecosystem balance. Atmospheric gravity waves are a small and medium-scale disturbance phenomenon with vertical propagation properties. plays an important role in meteorology, climatology, chemistry, and the dynamics of the stratosphere and the middle layer. The most obvious sources of gravity waves include terrain, convection, and wind shear. The important driving source of the internal small-scale turbulent mixing process, the development and fragmentation of gravity waves can also exchange materials. In fact, the Qinghai-Tibet Plateau is an important source of atmospheric gravity waves, and the convective activities are very strong. It is the material exchange between the stratosphere and troposphere. In the key area of ​​the UTLS, domestic scholars have studied the mass exchange between the stratosphere and troposphere during the gravity wave process of the Qinghai-Tibet Plateau, and found that the gravity wave process will affect some gas components in UTLS such as CH 4 , NO 2 However, how the UTLS ozone on the Qinghai-Tibet Plateau responds to the gravity waves generated in this area has not yet been carried out. In the polar regions, previous studies have shown that terrain gravity waves will affect the chemical reactions on the stratospheric cloud particles in the polar regions Stratospheric ozone is an important source of gravity waves. Whether the gravity waves generated by the topography of the Qinghai-Tibet Plateau will affect UTLS ozone has not yet been explored, so it cannot provide protection for human survival, nor can it provide evidence for changes in weather and climate. Therefore , the present invention proposes a method for analyzing the response of UTLS ozone on the Qinghai-Tibet Plateau to gravity waves to solve the problems in the prior art
