Description
The theme of the research project: "Antarctic tropopause over the station Marambio in the conditions of the ozone hole during 2004-2019". The object of study is the polar tropopause of the Southern Hemisphere. The subject of the study is the change in the height of thermal and ozone tropopauses in the ozone hole. The aim of this work is to improve the understanding of the distributions and variations of the ozone content of the upper troposphere - lower stratosphere in the polar region and the feedback between changes in ozone content and tropopause height. The project used high-resolution data from polar ozone probes emitted over the Marambio meteorological station. The main practical part of the work was the analysis of the peculiarities of the change of thermal and ozone tropopauses, their comparison, the concentration of ozone at their heights over the Antarctic region. The results are important not only in terms of establishing the general ratios of atmospheric parameters, but also in view of the significant impact of changes in altitude and clarity of the tropopause on metabolic processes (especially ozone) between the stratosphere and troposphere. The processes of stratospheric-tropospheric exchange and tropopause dynamics, in turn, play a significant role in regional climate change and through the chain "tropopause-ozone-ultraviolet content" affect the state of local ecosystems. Therefore, the study of processes in the field of the tropopause is of considerable practical and scientific interest and the continuation of work in this direction is very important.
