Electric field disturbance in the Earth-ionosphere layer Original Research Article

Theoretical studies of the electric field disturbance due to a variation of the atmospheric current, flowing between ionosphere and the Earth, are carried out. This variation is caused by a conductivity variation and the electromotive force generation in the near-ground atmospheric layer. The increase of the atmosphere radioactivity level near the ground results in substantial increase of electric field in the lower ionosphere. Electromotive force generation in lower atmosphere leads to field increase or decrease or to the sign change in the ionosphere, depending on its direction and value.
