Abstract

The variability of Antarctic total column ozone in 1980–2018 is considered. The study analyzes trends in Antarctic total column ozone during the study period as well as the physical and chemical processes affecting the seasonal variability of total column ozone. The main attention is paid to the influence of dynamical processes on the stability of the Antarctic polar vortex, to the formation of polar stratospheric clouds, and to the influence of gas-phase and heterogeneous processes on the surface of polar stratospheric clouds and sulfate aerosol. The method of research is the analysis of the results of ground and satellite observations and numerical modeling of physical and chemical processes over the Antarctic using a global chemistry transport model with the dynamical parameters specified from reanalysis data.

理化因素对南极臭氧年际变化影响的数值模拟

摘要

考虑了1980-2018年南极总柱臭氧的变化性。该研究分析了研究期间南极总柱臭氧的变化趋势以及影响总柱臭氧季节变化的物理和化学过程。主要关注动力学过程对南极极地涡旋稳定性的影响，极地平流层云的形成以及气相和非均质过程对极地平流层云和硫酸盐气溶胶表面的影响。研究方法是使用从重新分析数据中指定的动力学参数的全球化学传输模型，对南极地面和卫星观测结果进行分析，并对物理和化学过程进行数值模拟。
