Snapshot of an epoch of a grand maximum followed by a grand minimum for solution run 4. Top panel shows the toroidal magnetic field in a time-latitude diagram extracted at r/R = 0.85. The bottom panel shows four meridional planes snapshots extracted from the simulation at times indicated by the dashed lines on the upper panel. The color scale encodes the toroidal magnetic field, and poloidal fieldlines are plotted as solid (dashed) lines for counterclockwise (clockwise) orientation.
