Modeling of Atmospheric Tides with Account of Diurnal Variations of Ionospheric Conductivity

详细

A semiempirical model of ionospheric conductivity for calculating the coefficients of ionic friction and magnetic twisting is described. The influence of diurnal variations of the ionic friction and magnetic twisting in the upper atmosphere on the formation of latitudinal and altitudinal structures of various components of atmospheric tides is considered. It is shown that taking into account diurnal variations of the ionic friction and magnetic twisting leads to an additional generation of non-migrating tides in the thermosphere due to the nonlinear interaction of migrating tides with these variations.
