Abstract
The duration of polar ozone depletion events depends on the phase of the quasi-biennial oscillation (QBO). The QBO determines the location of the subtropical critical wind line that influences the propagation of planetary waves into the stratosphere. As a result, the polar vortex intensifies during the western phase of the QBO and weakens during the eastern phase, which manifests itself in the timing, duration, and intensity of stratospheric ozone depletion. Polar ozone depletion occurs inside the strong polar vortex from late winter to spring due to the occurrence of heterogeneous and photochemical ozone destruction reactions in the presence of solar radiation. We studied the effect of QBO phases at different isobaric levels on the dynamics of the stratospheric polar vortices based on satellite data from the Goddard Space Flight Center NASA. It is shown that the QBO at the 30 hPa pressure level has a predominant effect on the dynamics of the polar vortices. This is observed from September to December, especially in October and November, in the dynamics of the Antarctic polar vortex, and throughout the entire period of its existence in the dynamics of the Arctic polar vortex.
