Quasielectrostatic model of atmosphere-thermosphere-ionosphere coupling Original Research Article

Multiple experimental evidences obtained recently convincingly show the strong influence of near ground atmospheric processes (volcano eruptions, sand storms, radioactive air pollution, earthquakes etc.) on the upper layers of thermosphere and ionosphere. The correspondent model explains the observed phenomena by the quasi-electrostatic field effects. The model consist of three parts: 1-electric field generation model, 2-electric field penetration at thermosphere-ionosphere heights, and 3-effects of electric field in the thermosphere-ionosphere. In the first part a model of ion kinetics in a near-ground layer of troposphere is considered. It explains the appearance of strong vertical electric field up to several kV/m. Second part with the help of existing model of atmosphere conductivity vertical distribution makes calculations of penetrated electric field at the heights from 90 up to 1000 km. It explains the horizontal electric field ∼ 1 mV/m at the ionospheric heights as a result of original vertical electric field ∼ 1 kV/m at the ground surface. The third part demonstrates the effects of electron concentration modification over the vertical electric field source. Self-consistence of the model is demonstrated by correspondence of the calculated parameters to the measured experimentally.
