Fig. 7From: Global MHD simulation of magnetospheric response of preliminary impulse to large and sudden enhancement of the solar wind dynamic pressureDependence of PI amplitude solar wind velocity. The horizontal axis is the solar wind velocity, and the vertical axis is the horizontal component of the magnetic field. The solid line indicates the horizontal component of the magnetic field variation at 15 magnetic local time and 63° magnetic latitude, and the dashed line indicates that at 15 magnetic local time and 26° magnetic latitudeBack to article page
