Short summary
The plasmaspheric plume is an important region of detached plasma elements and provides an effective coupling channel of energy/mass between the inner magnetospheric plasmasphere and outer magnetosphere. In this study, using Van Allen Probe data, we present a statistical result of plasmaspheric plumes in the inner magnetosphere, which implies that the plumes tend to occur during the recovery phase of geomagnetic storms, and the occurrence rate is larger during stronger geomagnetic activity.
