Abstract:

Clearly expressed maxima of aerosol scattering were recored in Tomsk in January, 2010 from lidar observations in stratosphere at altitudes from 14 to 24 km. Calculations of back trajectories of air mass transfer to Tomsk demonstrated that enhanced aerosol scattering was directly related to air mass cooling for 6-12 h before its occurrence over Tomsk in the regions below thresholds for polar stratospheric cloud formation. The calculated back trajectories demonstrated that the polar stratospheric clouds registered in Tomsk at altitudes of 16-24 km could be formed over the Scandinavian mountains, and the clouds at altitudes of 11-14 km could be formed over mountain ridges of Polar Ural Mountains and Novaya Zemlya Archipelago. The presence of the stratospheric aerosol of synoptic scales in these regions in January, 2010 was confirmed by the data of CALIOP satellite lidar.
