Studying the quasi-biennial oscillation of total ozone and ozone concentrations at separate altitude levels over the Arctic and Tomsk according to data of TOMS satellite instrumentation

The paper analyzes 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 from the TOMS satellite instruments. The correlation coefficient between TO changes and variations in equatorial zonal wind for the period of 1996–2013 is statistically insignificant. The springtime (March–April) aver-age ozone concentrations and zonal wind mostly show the correlation in the interval–0.23–0.26. The mixing ratio time series, composed for separate altitudinal levels over the period 2005–2013, exhibit quasibiennial oscillation, which takes shape at altitudes of ~30 km and weakens in overlying regions. The correlation dependence between the ozone mixing ratio and the equatorial zonal wind index is most distinctly manifested in the Western hemisphere and is more complex in the Eastern hemisphere.
