Fig. 2From: Global MHD simulation of magnetospheric response of preliminary impulse to large and sudden enhancement of the solar wind dynamic pressureThe horizontal component of the magnetic field variation derived from the ionospheric Hall current at three different longitudes (three panels) at four different latitudes (four lines in each panel) in the simulation results for run10n and run10v. One division in the vertical axis is 100 nT. The horizontal axis is time. MLT magnetic local timeBack to article page
