The conditions under which AGW are realized at the same frequency are found. The propagation of evanescent (horizontal) acoustic-gravitational waves in an isothermal stratified atmosphere has been studied. The dominant role of the global migrating current in the generation of the alternating magnetic field of the Sun has been established. As a result of numerical calculations based on the kinematic dynamo model, a scheme of latitudinal-temporal distribution of relative amplitudes of meridional and azimuthal magnetic components on the Sun's surface during a 22-year magnetic cycle is constructed. The problem of penetration of electric fields from atmospheric near-Earth sources of electric current into the ionosphere as a part of dynamic modeling of equations is investigated. A perturbation theory based on the method of transforming the inverse scattering problem for solitons has been developed, which describes short-wave ioncyclotron waves in plasma observed in the Earth's magnetosphere. Using the kinetic approach, a new nonlinear equation for longitudinal waves with a scale smaller than the Debye radius in an electron-positron plasma with ultrarelativistic temperatures is derived. The vortex dynamics of electron beams in the framework of the Io - Jupiter interaction is considered. For the first time in the world practice, models for forecasting geomagnetic elements X, Y, Z have been obtained. The results of such forecasting for the magnetic observatory "Lviv" with a forecast depth of 3 hours are presented. Product Description popup.authors Vlasov Dmytro I.
