Abstract

The winter of 2022-2023 was characterized by intense dynamic processes associated with the formation of blocks in the middle troposphere and the occurrence of sudden stratospheric warmings (SSW) in the stratosphere. The SSW event in January-February 2023 is likely related to prolonged blocking over the Urals and Europe in the second half of January. Lidar measurements of atmospheric temperature based on the use of pure rotational raman spectra on nitrogen and oxygen molecules at altitudes up to 70 km in the Akademgorodok area of Tomsk during the SSW period, and their comparison with WACCM model data and satellite Aura data showed a number of characteristic features associated with changes in the structure of the stratopause due to SSW.
