Time-latitude diagrams of various quantities from a SFT simulation run with magnetic-field dependent meridional inflows towards the activity belts. From top to bottom: longitudinally averaged signed radial magnetic field, longitudinally averaged unsigned radial magnetic field, meridional flow velocity, and meridional flow perturbation (Δν(λ,t), saturated for values exceeding  ± 2   m s^-1). Black vertical lines indicate the termination of the RGO sunspot data in 1976.
