Mean toroidal magnetic field evolution as time-latitude (butterfly) diagram, plotted at a radius r = 0.98 R (top row) and time-radius diagram plotted at a 25° latitude (middle row) in kG during a 20 yr interval in the saturated stage for Runs A1, A1pc, A3, A3t, and B1. For Run B1, we plot the butterfly diagram at radius r = 0.84 R and its time interval is 40 yr. The dashed horizontal lines mark the equator (θ = π/ 2) and the radii r = R, r = 0.98 R and r = 0.85 R, respectively. Propagation of the mean magnetic field for the same runs (bottom row). Color coded is plotted during the saturated stage together with white arrows showing the direction of migration of an αΩ dynamo wave (Parker 1955; Yoshimura 1975); see Warnecke et al. (2014). We suppress the arrows above r = 1.05. The black solid lines indicate isocontours of at 2.0 kG. The dashed white lines indicate the surface (r = R).
