摘要:
The polar slantEcondition (SEC) whose most prominent feature is the Ess ionogram trace is taken as evidence of an ion acoustic instability driven by strong electric fields and thus as evidence of strong plasma flow. The occurrence of SEC in the northern polar cusp region strongly suggests that the throat region of rotational plasma flow into the polar cap does not move in local time when the sign of the IMFBychanges.
