QBO Signal in Total Ozone Over the Tibet
青藏高原臭氧的准两年振荡

From data analysis of ozone satellite observation and general circulation, this article dis-cusses the seasonal and inter-annual variations of total ozone over the Tibet. Analysis has been done on quasi-biennial oscillation (QBO) in inter-annual ozone variation over the Tibet, in comparison with QBO over the tropics and non-mountain region at the same latitudes of the Tibet. The fact is shown that the Tibet ozone QBO has averaged period 29 months, with averaged amplitude S DU. The Tibet ozone QBO is anti-phase against the stratospheric wind QBO over the tropics, i.e., when the tropics 30 hPa-wind is easterly, ozone has a surplus, and vice verse. This article also discusses the impact of atmospheric transfer on ozone QBO over the Tibet.
