Influence of ocean on dynamic of polar stratosphere and ozone layer

Abstract

Influence of the tropical oceanic processes (the El-Niño – La-Niña phenomenon) on structure and composition of a polar stratosphere is considered. Data of the reanalysis on sea surface temperature, a potential vorticity, temperatures of air, ozone mixing ratio and total ozone column per 1980–2016 are analyzed. Influence the El-Niño and La-Niña on circumpolar vorticity, temperature of air in a stratosphere and an ozone layer is studied. It is shown that the El-Niño leads to instability of circumpolar vorticity, causes sudden stratospheric warming and increase the content of ozone.
