Asymmetries generated from our model by introducing 50% fluctuations in the poloidal field generation mechanism. Panel (a): scatter plot of the rise-to-decay time ratio versus cycle number. Panel (b): scatter plot of cycle amplitude (in Gauss) versus rise time (in years). Panel (c): scatter plot of cycle amplitude versus rise rate (in units of Tesla/year). Panel (d): scatter plot of cycle amplitude versus decay rate near the preceding cycle minimum (in Tesla/year).
