The Gnevyshev-Ohl pattern in our full-disk toroidal proxy. Panel A) shows the sequence of cycle maxima (black), and the corresponding 1-2-1 running mean thereof (dashed); subtracting the latter yields the detrended sequence plotted in panel B). The G-O pattern shows up here as a sustained regular alternance between positive and negative detrended values, e.g. between simulated cycles 16 and 30 (thick segments). Panel C) shows a similarly detrended cycle amplitude sequence for the monthly smoothed SSN; here the G-O pattern holds uninterrupted from sunspot cycle 9 to 21 (thick segments).
