Left panel: time history of α (blue curve), α_Max (red curve), and α_Rey (green curve) in model Z-C-Re3000. Right panel: scatter plot showing the total angular momentum transport rate α as a function of α_axi which measures the angular momentum transport due to and modes for 120 dumps evenly spaced over model Z-C-Re3000. The green curve plots an approximate fit to the data (see text for details).
