Es layer and dynamics of neutral atmosphere during the periods of geomagnetic disturbances

Abstract

Analysis of geomagnetic activity influence on parameters of E sporadic layer for ionosphere sounding station Moscow (56 N, 37 E) and on dynamics of neutral wind in the upper mesosphere-lower thermosphere for meteor radiolocation station Kazan (56 N, 49 E) was conducted. Discovered regularities of E sporadic layer response on geomagnetic disturbances are explained by the direct change of neutral atmosphere dynamics during the geomagnetic disturbances. © 2001 Elsevier Science Ltd.
