| Zusammenfassung |
| In this paper we study an instability of the
plasma moving towards the Earth near the inner plasma sheet boundary. We include
both the interchange instability of the plasma sheet and the
magnetosphere-ionosphere interaction instability caused by an effect of
field-aligned currents (connected with electron precipitation) on ionospheric
conductivity. The instability leads to the separation of steady-state
magnetospheric convection into parallel layers. This instability may be
responsible for the appearance of quiet auroral arcs inside region 2 of
field-aligned currents flowing out of the ionosphere. This instability allows us
to explain also the existence of crossing auroral arcs. |
