(a)–(d) The variation in the solar wind velocity (V), density (N), subsolar distance of the magnetopause, dynamic pressure (Pd), SYM-H and ASYM-H during magnetic storms in GROUP 2 (a, b) and 3 (c, d). Blue shaded regions denote modeled GMC events, green shaded regions indicate GMC events observed by GOES satellites. Red and blue bars describe the time interval of calculated median value of V, N and Pd described in Table 1.
