Butterfly diagram for one realisation of the synthetic BMR input record. Different colours encode magnetic flux emerging in BMRs within one-month periods over 2° latitude bins. Blue corresponds to < 1 × 1021 Mx magnetic flux emerged in BMRs, green to 1 − 10 × 1021 Mx, black to 1 − 3 × 1022 Mx, red to 3 − 6 × 1022 Mx and yellow to > 6 × 1022 Mx. The vertical dashed lines mark cycle minima.
