Abstract

In the article the lidar observations of the winter stratosphere warming manifestations of (SW) 2011-13 over Tomsk are considered. In 2010/11 the winter warming took place in January with insignificant positive temperature deviations from the mean monthly values in its first decade and then two maxima on the 14^th and 15^th of January at the altitude of 30-40 km with a deviation to 45К. In 2011/12 the beginning of the SW was recorded from lidar measurements on December 26 and lasted for two decades of January. The maximum development of SW was at the end of December 2011 – the first decade of January. The biggest temperature deviations were at the 40-60К level in the height interval of 35-45 km. In 2012/13 the SW began on December 25. The phase of its maximum development fell on the 1-4^th of January when the stratopause altitude dropped on 30 km and the maximum temperature deviation from the model at this level reached 70K. In contrast to the first two warming (minor), the last was referred to the major type wherein air mass circulation change happened in the upper stratosphere over Tomsk ((http://www.geo.fu-berlin.de/en/met/ag/strat/index.html).).
