The paper investigates the excitation of currents and winds in the dynamo region of the ionosphere by mass transfer in the plasmasphere induced by magnetospheric convection. Plasma flow across the magnetic field lines in the plasmasphere generates an electric field which drifts to the low and midlatitude ionosphere. The electric field creates a potential distribution which produces an Sq-like current system and a wind system. The basis of the analysis is the assumption that the ionospheric electroconductivity depends on azimuth, which allows one to calculate the semi-diurnal harmonics of current and wind, and to determine the effect of local-time variations of the conductivity on the diurnal harmonics of current and wind.
