Numerical Simulation of Ionospheric and Plasmaspheric Dynamics.
Abstract
The development of computational schemes for numerical modelling of the plasmapause and the aurorally-induced plasma density gradients is described. Variations in location of the equatorial plasmapause are simulated using computer-generated maps representing an ensemble of test particles evolving under co-rotational and convection electric fields. The model has been used to estimate the Transition Time (T sub p) from one stable, equilibrium plasmapause configuration to another and to reproduce Disturbance Scenarios wherein the hour-by-hour changes in plasmapause location at a given local time L sub pp(LT) associated with specified variations in geomagnetic activity are followed. The results of calculations using both models show that plasma transport effects either dominate or at least significantly contribute to the spatial and/or temporal characteristics of the plasma density feature in question.
