Method for analyzing response of UTLS ozone in Qinghai-Tibet Plateau to gravity waves

Abstract

The invention discloses a method for analyzing response of UTLS ozone to gravity waves in the Qinghai-Tibet Plateau. The method comprises the following steps: gravity wave selection, numerical simulation scheme, gravity wave feature analysis, response of UTLS ozone to gravity waves and WRF mode simulation result analysis. According to the method, terrain gravity wave events occurring above the Qinghai-Tibet Plateau area are subjected to comparison and simulation analysis through European center reanalysis data ERA5 and a mesoscale mode WRF; more information is provided for acquisition of gravity wave information through a Suomi satellite view angle from top to bottom; the response of the UTLS ozone in the Qinghai-Tibet Plateau to the gravity wave is explored from the dynamic process of thegravity wave, and a certain scientific basis is provided for further research in the future, so the guarantee is provided for human survival, and a basis is provided for the change of weather and climate.

Description

technical field [0001] The invention relates to the technical field of ozone response to gravity waves, in particular to a method for analyzing the response of UTLS ozone on the Qinghai-Tibet Plateau to gravity waves. Background technique [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 atmosphe...

[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 strato
