Abstract

The influence of winter stratospheric warming (SW) on the special features of the vertical distribution of the temperature and air density in the middle atmosphere over Tomsk is analyzed. Sudden SWs in winters of 2009– 2010 and 2010–2011 and summer of 2010–2011 are considered with stable vertical temperature distributions. It is demonstrated that in the perturbed state caused by SWs the deviations of the temperature and air density from their average values were in antiphase. Their maximal amplitudes were observed at altitudes 35–40 km and could reach +30% for temperature and 30% for air density. Under quiet conditions in summer months, the temperature deviations were in the main corridor –6 – +8%, and the air density deviations lay in the corridor 8– 15%.
