Quasi-biennial oscillation of the total ozone and ozone concentrations at separate altitude levels over Arctic and Tomsk according to TOMS,OMI, and MLS observations

We analysed 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 Total Ozone Mapping Spectrometer (TOMS), the Ozone Monitoring Instrument (OMI), and the Microwave Limb Sounder (MLS), flown on different satellite platforms. The correlation coefficient between TO and equatorial zonal wind for the period of 1996–2013 is statistically insignificant. The spring (March–April) average ozone concentrations and zonal wind mostly show the correlation in the interval from ?0.23 to ?0.26. The mixing ratio time series, composed for separate altitudinal levels over the period of 2005–2013, exhibit quasi-biennial oscillation, which is weakly manifested at lowest heights, takes shape at heights of ~30 km, and weakens in overlying regions. The correlation between the ozone mixing ratio and the equatorial zonal wind index is most distinct at Western Hemisphere sites and more complex in the Eastern Hemisphere.
