Research of Antarctic ozone circumpolar vortex using satellite data

A model of Antarctic ozone circumpolar vortex (CV) is proposed with gradient wind as a base. It was found that at time of the vortex formation the total ozone maximum is concentrated in the 45° S and the CV average diameter is 9000 km. It was confirmed with measurements from satellite data. It is shown that at the time of the vortex formation there is ozone redistribution between the inner region of CV and its periphery, it furthers to the Antarctic ozone anomaly appearance. The zonal wind speed in CV was evaluated theoretically and experimentally.
