Abstract
The temperature vertical distributions over Tomsk in disturbed and quiet periods of the year over 2012-2015 are analyzed. The experimental material accumulated show some features of the annual dynamics in the thermal regime of the stratosphere. Thus, the winter stratospheric warming occurs annually. During the period specified, there was one strong (major) warmings, in winters 2012/13, when air mass transport in the upper atmosphere changed from the western to the eastern, and three weak (minor) LINK Word.Document.12 "D:\\2017-12\\Маричев_03.03.2017\\Лидарные исследования термического режима стратосферы над Томском за период 2012_ред.docx" "OLE_LINK1" \a \r \* MERGEFORMAT warmings, in winters 2011/12, 2013/14, and 2014/15. Based on long-term observations, it is shown that the temperature vertical distribution for Western Siberia is in a good agreement with the CIRA-86 model distribution in the majority of cases throughout a long period of the year (from April to November).
