Variation of monthly smooth (a) Equatorial electrojet strength in the Indian longitude (EEJ), (b) disturbed time storm current (Dst), (c) High latitude auroral electrojet current (AE) as a function of time for SCs 22, 23, and 24. The 13-month smooth variations of these parameters are shown by yellow solid line. Vertical dashed-dotted lines indicate the time of start (black), and peak (red) for SCs 22, 23, and 24.
