Resumo

The results of analyzing the planetary and tidal variabilities in the mesosphere, thermosphere, and ionosphere acquired in calculations for January 2009 using two versions of the EAGLE model are presented. It is shown that, during a sudden stratospheric warming (SSW), the planetary and tidal-wave activity increases in the lower thermosphere. The features of the changes in solar-migrating and nonmigrating components of tidal variabilities in the parameters of the thermosphere, ionosphere, and electric fields are considered. The reproduction of the vertical electromagnetic drift during the SSW period over the Jicamarca station is explained by a significant increase in the diurnal and semidiurnal tidal variability.
