a Autocorrelation as a function of initial calendar month (x axis) and lag month (y axis) for the NiƱo3.4 index. b Autocorrelation decline rates (ADRs) in (a). Values of the rate are plotted in contours and shaded boxes, respectively, where the interval is 0.05. White numbers in shaded boxes denote the target calendar month in the lag month domain. c ADRs as a function of target calendar month and lead month for the NiƱo3.4 index, where the interval is 0.05. d Mean ADRs for all 12 lead months (left y axis: blue bar) and the frequency of the maximum ADRs (right y axis: red bar) as a function of the target calendar month (x axis) for the NiƱo3.4 index
