Temporal evolution of the longitudinally-averaged magnetic fields and horizontal velocities for the dynamo simulation with deeper Babcock-Leighton α-effect (Δr_bmr = 0.12 R_⊙). (a) Azimuthally-averaged radial field ⟨B_r⟩ at the surface r = 0.985 R_⊙. (b) Azimuthally-averaged toroidal field ⟨B_ϕ⟩ near the base of the convection zone r = 0.715 R_⊙. Black solid lines are the contours of the emerged BMRs at each time. (c) Torsional oscillation pattern δ⟨Ω⟩ at the surface. (d) Azimuthally-averaged latitudinal velocity ⟨v_θ⟩ near the base of the convection zone.
