Based on the analysis of lidar sounding data on stratospheric ozone and temperature over Tomsk in January—March 1996—2000, the influence of global geophysical processes on the vertical distribution of ozone and temperature is studied. To determine the statistical importance of their contribution to the vertical ozone and temperature distribution, 18 global geophysical processes are analyzed, including quasi-biennial oscillations, solar activity, World Ocean sea surface temperature, Arctic, Antarctic, Pacific, and other subglobal oscillations, etc. A quantitative contribution of each process to ozone and temperature profiles in the lower stratosphere is determined. It is shown that lidar monitoring data can be used for detecting and diagnosing long-term changes in the state of the lower stratosphere.
