Fig. 3From: Global MHD simulation of magnetospheric response of preliminary impulse to large and sudden enhancement of the solar wind dynamic pressureHorizontal component of magnetic field variation derived from Hall current in the simulation at 15 magnetic local time and 63° magnetic latitude. The upper panels show the results for a fivefold increase, and the lower panels show the results for a tenfold increase. The left panels show the results for the density jump condition, and the right panels show the results for the speed jump condition. PI preliminary impulse, MI main impulseBack to article page
