Abstract:

The paper analyzed the pattern of the quasi-biennial oscillation of the total ozone (TO) and ozone concentrations at separate altitudinal levels in the stratosphere over Arctic territory and Tomsk according to data of TOMS satellite instrumentation. The correlation coefficient between TO changes and variations in equatorial zonal wind for the period of 1996–2013 is statistically insignificant. The average springtime (over March–April) values of ozone concentration and zonal wind mostly show the correlation in the interval of –0.23÷–0.26. The time series of the mixing ratio, composed for separate altitudinal levels over the period of 2005–2013, exhibit quasi-biennial oscillation, which takes shape at heights of ~30 km and weakens in overlying regions. The correlation dependence between the ozone mixing ratio and the equatorial zonal wind index most distinctly manifests itself in the Western Hemisphere and is more complex in the Eastern Hemisphere.
