Fig. 1

Overview of simulation results for density jump condition (run10n) and speed jump condition (run10v) with a tenfold increase in solar wind dynamic pressure. The upper panels of each case show color contours of the field-aligned current (FAC) in the polar ionosphere. The lower panels of each case show color contours of the static pressure and velocity vector unit at the equatorial plane in the magnetosphere. The sunward direction is to the left. The series of figures from left to right represents the time development of the SC. The contour interval is 2.22 μA/m2 for the FAC and 41.6 × 10−11 N/m2 for the pressure
