On the Features of Magnetogradient Planetary Waves in the Approximation of the Spherical Symmetry of the Ionosphere

Abstract

A problem of propagation of very long planetary waves in the upper atmosphere of the Earth is investigated. A new exact solution of the magnetohydrodynamics equations of the ionosphere in the spherical coordinate system is found taking into account the Earth's rotation and geomagnetic field. The general dispersion equation for the planetary waves in the E and F regions of the ionosphere is derived and propagation of these waves in weakly ionized ionospheric plasma are studied.
