This paper analyses disturbances of the Earth's middle atmosphere temperature regime associated with sudden stratospheric warmings observed over West, East Siberia and Russian Far East in January-February of 2008-2010. The analysis rests on data on vertical temperature distribution in the upper troposphere and stratosphere obtained from lidar measurements over Tomsk, Yakutsk and Paratunka, the Kamchatka Krai. For the complex analysis of the spatial-temporal temperature distribution in the middle atmosphere, the lidar measurement data are exploited along with satellite data on temperature acquired by "Aura" Microwave Limb Sounder (MLS). This paper addresses regional effects of sudden stratospheric warmings over the Asian region of Russia in the longitudinal sector of ~85ч-160° Е during winters of 2008-2010.
