The Energy Collection and Dissipation in the Compressible Magnetotail

Abstract

In this paper, we have derived the nonlinear wave equations of the shear flow at the magnetotail from compressible MHD equations by the two-dimensional reductive perturbation method, and then discussed the nonlinear processes of energy dissipation and transfer at different region in the magnetotail. At last, the effects of disturbed electric field was discussed.
