Fig. 4From: Global MHD simulation of magnetospheric response of preliminary impulse to large and sudden enhancement of the solar wind dynamic pressureDependences of PI amplitude (left) and rise time (right) on solar wind dynamic pressure. The horizontal axes are the square root of the normalized pressure (left) and the rise time (right). The vertical axis indicates the magnetic field amplitude of the PI. Open triangles and open squares indicate speed jump and density jump conditions, respectivelyBack to article page
