Abstract. The large-scale, quasi-steady geomagnetic perturbations at high latitudes are primarily controlled by the interplanetary magnetic field and solar wind parameters. In this study we employ a linear regression model to predict the ionospheric electric potential distributions over both the Northern and Southern polar regions on the basis of measured interplanetary magnetic field and solar wind velocity near the Earth's orbit. This linear model of ionospheric electrodynamics is also able to provide global patterns of the ionospheric convection, electric fields, ionospheric and field-aligned currents, and Joule heating rate.
