摘      要：This paper presents the modified magnetohydrodynamic(MHD)model and simulations of solar wind-magnetosphere *** use the two-dimensional and three-component,compressible,resistive,ion gyroviscous and Hall MHD model,i.e.,including the ion Unite Larmor radius(FLR)and Hall MHD effects,but neglecting the electron inertia and electron FLR *** composed dynamic pressure pulses(shear variations in the How velocity)in the solar wind form gusts that continually buffet the magnetosphere and cause the time-dependent magnetic reconnection at the *** results show that the magnetic Held and the How velocity components perpendicular to the reconnection plane can be generated in magnetopause current *** vortical How structures can also occur in the magnetospheric side *** results are responsible for non-ideal MHD properties of the plasma fluid,i.e.,ion FLR and Hall MHD effects.
