Abstract

This paper presents a result of model calculation of the disturbance dynamo electric field, prompt penetration, overshielding and their ionospheric effects during geomagnetic storm on December 14\textendash15, 2006. The calculations were carried out with use of the Global Self-Consistent Model of the Thermosphere, Ionosphere and Protonosphere (GSM TIP model) developed in WD IZMIRAN. Simulations were performed for quiet and disturbed conditions with took into account the magnetospheric convection electric field with and without took into account dynamo electric field. It has allowed to neglecting thermospheric and ionospheric effects of the disturbance dynamo electric field. The analysis of model calculation results was carried out. We have made conclusions about the role of the disturbance dynamo electric field, prompt penetration electric field and overshielding effects in thermospheic and ionospheric parameters during geomagnetic storm.
