ANALYSIS OF THE QUASI-BIENNIAL OSCILLATIO N IN THE VERTICAL-DISTRIBUTION OF OZONE AND METEOROLOGICAL PARAMETERS FROM OZONOSONDE DATA

An analysis is made of the quasi-biennial oscillation (QBO) in ozone c ontent, temperature, and meridional and zonal wind components in vario us regions Using ozone sounding data. In some atmospheric layers, the autocorrelation functions reveal oscillations with periods in the rang es of 3-7 and 11-14 years along with the QBO. Deviations of the averag e distribution of the ozone content and temperature from their many-ye ar monthly mean values in the eastern and western phases of the equato rial zonal stratospheric winds were determined using the superimposed epoch method. The ozone content deviations in the stratospheric layers are positive in the eastern phase and negative in the western phase o f the equatorial wind QBO at the 50-hPa level. The maximum QBO effect in the ozone content is detected between 16 and 24 km. The maximum eff ect layer in the Northern Hemisphere (NH) decreases in altitude from s ubtropical to middle and high latitudes. The ozone content QBO over Au stralia are approximately in phase with those over the nontropical sta tions of the NH. The ozone content and temperature QBO at subtropical latitudes of the NH are in phase with each other within the lower stra tosphere (16-24 km) and in antiphase within the 28-32-km layer. No dir ect relation is detected between the dominating periodicities in the o zone content, temperature, and wind components in the majority of atmo spheric layers at nontropical latitudes. The regional character of the QBO effects is significant at middle latitudes.
