| Zusammenfassung |
| An extensive study of ring current injection and intensification of the
storm-time ring current is conducted with three-dimensional (3-D) test
particle trajectory calculations (TPTCs). The TPTCs reveal more accurately
the process of ring current injection, with the main results being the
following: (1) an intense convection electric field can effectively energize
and inject plasma sheet particles into the ring current region within 1–3 h.
(2) Injected ions often follow chaotic trajectories in non-adiabatic
regions, which may have implications in storm and ring current physics. (3)
The shielding electric field, which arises as a consequence of enhanced
convection and co-exists with the injection and convection electric field, may
cause the original open trajectories of injected ions with higher energy to
change into closed ones, thus playing a role in the formation of the symmetric
ring current. |
