Equatorial ion convective velocity in the inner magnetosphere has been deduced from ROCSAT-1 and DMSP measurements of ion drift velocity in the ionosphere. Convective velocities are mapped from the ionosphere to the equatorial plane based on the equipotential assumption along magnetic field lines. We report here for the first time signatures of equatorial convective velocity in association with the plasmaspheric drainage plume, which was observed by IMAGE EUV instrument during the recovery phase of the 2000 Bastille Day magnetic storm. The azimuthal profile of the zonal convective velocity deduced from the ROCSAT-1 data indicates a sharp azimuthal gradient at the sunward edge of the plasmaspheric plume as the zonal velocity changes from sunward to anti-sunward direction. Thus the plasmaspheric plasma in the inertial frame was sub-corotational before reaching the longitude of the plasmaspheric plume and became supra-corotational after passing the longitude of the plasmaspheric plume. The radial profile of the zonal convective velocity near the plume deduced from the DMSP data indicates an increase of strong sunward zonal velocity with radial distance. These results imply complicated electric field structures for producing plasmaspheric plumes.
