| Zusammenfassung |
| We report on the in situ identification of a narrow electrostatic
acceleration layer (electrostatic shock) containing intense plasma
turbulence in the upward current region, and its effect on auroral
particles. Wave turbulence recorded in the center of the layer
differs in character from that recorded above and beneath. It is
concluded that the shock is sustained by different nonlinear waves
which, at each level, act on the particles in such a way to
produce a net upward directed electric field. The main power is
in the ion acoustic range. We point out that anomalous
resistivities are incapable of locally generating the observed
parallel potential drop. |
