The influence of geomagnetic disturbances on the formation of aerosol layers in the stratosphere.

According to the results of lidar observations, carried out at night over Tomsk in March 1988 and 1989, aerosol layers with increased scattering properties were found at the altitude of about 45 km during magnetic storms. A characteristic feature of the dynamics of these formations was their lowering to the height of up to 10 km after the cessation of geomagnetic disturbances at the speed of about 5 km per day.  When magnetic storms occurred frequently (1989), almost linear profile of the height distribution of scatters with a positive gradient and a quasi-stationary aerosol downward flow was established.
