Abstract

Modulation of ionospheric plasma density by acoustic waves (AW) is investigated. A rigorous electrodynamic model of the interaction of acoustic waves, generated by the lithospheric displacements during the seismic event preparation, with the cold dense ionospheric plasma in the presence of a magnetic field is constructed in conjunction with the actual height variations of the plasma particles' mobility and conductivity tensors in the ionosphere. A mechanism of creation of ionospheric inhomogeneities with different scales and with various degree of disturbance ΔN/N_o=10^-4-10^-5 (N_o is the concentration of plasma electrons (ions) in background ionospheric plasma) is presented.
