Manifestation of Quasi-biennial Oscillations of Stratospheric Circulation in the Vertical Ozone and Temperature Distribution over Tomsk

摘要

Lidar sounding data of ozone and temperature in the stratosphere over Tomsk in the winter period of 1996-2000, the influence of the quasi-biannual stratospheric circulation cyclicity (QBO) on their vertical distributions have been shown. Interannual variability of the ozone content and temperature is observed distinctly in the range of heights of 18-30 km with the synchronous oscillations of the period 2 years. Maximum amplitudes of the oscillations by ozone as well as temperature are directed at the height of localization for maximum of the ozone layer of H=20km. Periodicity of the oscillations begins to appear from the lower heights for temperature (H≤16), but it extends up to H≈36km for ozone. Positive anomalies for vertical distributions of ozone and temperature as well as the total ozone column (TOC) were observed for even years (1996, 1998, 2000), and negative anomalies for odd years (1997, 1999)
