| 英文摘要 | The morphology of the plasmasphere during a geomagnetic storm is simulated by considering the two dimensional Ex B drift motion of plasmaspheric charged particles in the equatorial plane. assuming a time-independent dipolar magnetic field and a corotation electric field plus, a spatially uniform dawn-dusk convection electric field varying with K-p index, the spatial distributions of charged particles at different time during a geomagnetic storm are obtained. Our results show that if K-p increases with time, some particles inside the original plasmapause will convect into the magnetopause, forming a long tail that stretches from the plasmasphere to the magnetopause in the afternoon region. The particle convection weakens as K-p decreases, and as K-p returns to its not-mal value, the plasmasphere develops a thin tail that wraps around the Earth. |
