Abstract
Based on reasonable models of anisotropic electrical conductivities and solar and lunar tidal wind systems in the dynamo region (90–150 km altitude), distributions of electrostatic fields for Sq and lunar variations on quiet days in equinoctial months during moderate sunspot periods are estimated. These electrostatic fields produced in the dynamo region may be communicated to the magnetosphere along the earth's magnetic lines of force without appreciable attenuation. The communicated electrostatic field distributions in the magnetosphere are deduced, and drift motions of magnetospheric plasma particles caused by the coupling of the earth's magnetic and electrostatic fields are computed. An outward drift flow in the daytime and an inward flow at night with a speed of a few meters per second to several hundred occur for Sq. The drift speed for lunar variations is about 5% of that for Sq.
