The Numerical Simulation about MHD Responses of a Model Magnetosphere to the Magnetopause Perturbation

Abstract

There are many Pi pulsations in the magnetosphere. I report the behaviors of MHD based on various parameters of the perturbation among the magnetosphere having inhomogeneties of Alfven speed. I used one dimension of those models. As a parameter, I used a position of plasma pause and radial motion of magnetopause boundary.
