[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

Embodiment Construction

[0029] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0030] according to figure 1 , 2 , 3, 4, 5, 6, 7, and 8, the present embodiment provides a method for analyzing the response of UTLS ozone on the Qinghai-Tibet Plateau to gravity waves, comprising the following steps:

[0031] Step 1: Gravity wave selection

[0032] Firstly, the gravitational wave signal and ozone distribution over the Qinghai-Tibet Plateau are obtained through the ERA5 reanalysis data, and the gravity wave activity area over the Qinghai-Tibet Plateau is selected. The spatial resolution of the ERA5 reanalysis data is 0.25°×0.25°, and the vertical layer is from 1000hPa to 1hPa, a total of thirty-seven layers, and then get the thermal infrared band image of the gravi...
