The effect of geomagnetic activity on the dynamics of the upper mesosphere-lower thermosphere and on parameters of the Es-layer

Abstract

The present paper describes the effects of geomagnetic disturbances on the behaviour of the following dynamic process : prevailing wind, tide, meso-scale turbulent motions within the heights 80-110 kms of upper mesosphere-lower thermosphere. We investigated the geomagnetic effects as a function of altitude and season. As a result of our analysis some regularities of the influence of geomagnetic activity on the dynamics of the lower thermosphere have been revealed.
