From top to bottom: zoom-ins of the time-latitude diagram of the mean toroidal magnetic field near the surface (at Rs) and bottom (at Rb), the angular velocity variations, and the Reynolds stress components R and Rθφ near the surface (at Rs) during t = 20−65 yrs, showing that the magnetic cycle and surface activity are strongly disturbed (t = 20−45 yrs), after which the regular state is quickly recovered (t = 45−65 yrs).
