Results of Model 1, a flux transport BL dynamo model (Dikpati & Charbonneau 1999). Panel (a): temporal evolution of the surface induction integral I₁ (orange), equatorial induction integral I₂ (green), the total EMF integrals I₃ (red), and the net flux generation rate within the northern hemisphere $\frac{\mathrm{d}{\mathrm{\Phi }}_{\mathrm{tor}}^N}{\mathrm{d}t}$ (blue). Panel (b): snapshot of the poloidal field configuration at cycle minimum. Panel (c): time–latitude diagram of the surface radial magnetic field B_r. The vertical dashed lines in panels (a) and (c) mark the timing of cycle minimum, as shown in panel (b).
