Panel (a): Average Spearman’s rank correlation coefficients in colours averaged over the 50 disrupted days, for various values of K (vertical) and time points after model initialisation (horizontal, in minutes). The contours indicate the levels 0.5, 0.6, 0.7, 0.8 and 0.9. The vertical dashed line corresponds to 40 minutes after initialisation, which is used in the other panel. Panel (b): Spearman’s rank correlation coefficients at 40 min after initialisation. Individual days are split into days that have their maximum at values of \(K<9\) (in blue) and those that have their optimum performance at values of \(K\geq 9\) (in red). The black line indicates the 50-day average
