摘要：

Spatiotemporal variations of the quasi-biennial oscillation (QBO) in temperature and ozone over the tropical-subtropical belts (40 N-40-S) have been studied using Microwave Limb Sounder data for the period 1992-1999. Wavelet analysis has been performed to study inter-annual variations in amplitude and phases of the QBO. Latitude-height cross-sections of the amplitudes of temperature and ozone QBO exhibit a double-peak structure near the equator. Phase structure reveals that the temperature QBO descended faster than the ozone QBO. Cross-wavelet analysis shows an anti-phase relation between the amplitudes of the temperature and ozone QBO in the upper stratospheric region, whereas in-phase relation exists in the middle stratospheric region.
