The numerical modeling of the auroral electrojet during the geomagnetic substorm

Numerical modeling of the auroral electrojet behavior during the geomagnetic substorm has been performed based on the modified Global Self-consistent Model of Thermosphere-Ionosphere-Protonosphere system (GSM TIP). The effect of the enhanced during geomagnetic disturbances Region 1 field aligned currents, as well as the polar cap potential drop difference (which are model inputs), in the auroral electrojet distribution has been calculated. Both quasi-stationary solutions and time evolution of the auroral electrojet during geomagnetic disturbances have been obtained. It has been shown that the simulation results are in a rather good qualitative and quantitative agreement with the observations.
