Time latitude at r = 0.90R (upper panels), and time radius at θ = 15° latitude (lower panels), butterfly diagrams comparing the magnetic field evolution between simulations (a) P29, (b) P25, and (c) P21. The colored contours show the radial magnetic field intensity. The solid (dashed) lines show the positive (negative) contours of toroidal magnetic field.
