A kinematic α²Ω dynamo solution. Defining parameters are listed in Table 1 (solution run 0). The toroidal field component is plotted as a time-latitude diagram at depth r/R = 0.85 in the top panel, and meridional plane snapshots extracted at times corresponding to the dashed lines on the top panel, and spanning a magnetic half-cycle, are displayed at bottom.
