“…The electric current flow, which is due to a transfer and change in the type of charge carriers, leads to the formation of a layer of increased electron con centration. Figure 6 shows the calculated spatial dis tribution of the electron concentration obtained in (Laptukhov et al, 2009). The transfer of electrons downward leads to an increase in the plasma density at heights below 70 km.…”

“…The mechanism of the disturbance of the concentra tion of electrons and ions in the D region of the iono sphere was considered in (Laptukhov et al, 2009). This model considers the effect on a disturbance of the transport of electrons and ions in the D layer under the effect of electric field and heating of the electron com ponent of plasma by the field.…”

Electric field generation and its accompanying phenomena in the atmosphere-ionosphere system have been intensively studied in recent years. This paper considers the results of these studies, which have served as the physical basis for the model of lithosphere-ionosphere coupling. According to our model, the intensive processes in the lower atmosphere and lithosphere have an electrodynamic effect on the ionospheric plasma. The model was used to conduct theoretical studies of plasma and electromagnetic effects accompa nying the generation of conduction current in the global circuit. It has been shown that the electrodynamic model of the influence of seismic and meteorological processes on cosmic plasma can serve as a physical basis for a satellite system to monitor earthquake precursors and the catastrophic phase of typhoon development. The model makes it possible to couple the satellite data of electromagnetic and plasma measurements with electrophysical and meteorological characteristics of the lower atmosphere at the stage of earthquake prepa ration and typhoon initiation. The model suggests that the numerous effects in the cosmic plasma have a sin gle source: a change in the conduction current flowing in the atmosphere-ionosphere circuit.

“…The generation of conductivity current in the global circuit is accompanied by the modification of ionosphere. Perturbations in the D region of the ionosphere may be generated by both the transfer of charged particles and electron heating (Laptukhov et al, 2009). The electrons are in the upper part of D layer and negative charged ions are in the bottom part of D layer which occurs by quick adhesion of electrons to the neutral molecules.…”

This paper reviews modeling of the influence of earthquake (EQ) preparation processes on the ionosphere through the electric field and electric current occurring in the global atmosphere-ionosphere electric circuit. Our consideration is based on the satellite-and ground-based experimental data of electric fields, plasma and electromagnetic perturbations obtained for several days before an EQ. We have ruled out the models which are not consistent with the experimental data on the electric fields in the ionosphere and also on the ground surface. There has then been proposed a new model of the generation of electric field on the basis of injection of charged aerosols into the atmosphere, and we discuss the mechanism of lithosphere-atmosphere-ionosphere coupling. It is then shown that such changes in the electric field within the ionosphere induce a variety of plasma and electromagnetic phenomena associated with an impending EQ.

“…It was shown that the electric field at a height of about 60 km should reach 1 V/m in order to explain the observed effect. Laptukhov et al (2009) consider a model of generation of disturbances in the ionospheric D region as a result of charge transportation with flowing of an electric current. The electric field of the flowing currents leads to the transport of electrons and positively and negatively charged ions in the ionospheric D region.…”

This paper is devoted to the use of an electrodynamical model for lithosphere -atmosphere -ionosphere (LAI) coupling to explain plasma and electromagnetic earthquake (EQ) precursors. Our consideration is based on the calculation results of electromagnetic perturbations and ionospheric irregularities accompanying the electric field and electric current occurring in the global atmosphere -ionosphere electric circuit. Our theoretical results are confirmed by satellite-and ground-based experimental data of plasma and electromagnetic perturbations obtained for several days before an EQ. It is shown that the growth of current in the global circuit might result in the AGW (acoustic gravity wave) instability in the ionosphere, the formation of field-aligned current and plasma irregularities, magnetic field ULF oscillations and electromagnetic ELF radiation, spectral broadening of VLF transmitter signals registered by satellites, depressions of ULF magnetic pulsations, VHF radio emissions generated in the troposphere and propagation of the signals of a VHF transmitter behind the horizon. Moreover, the generation of electric current in the global circuit is accompanied with the modification of D, E and F ionospheric layers. All of these phenomena are shown to be attributed just to a single cause; namely, the variation of conducting electric current in the global circuit by the injection of charged aerosols into the atmosphere during seismic activity.
