Figure 2: ENSO-CLIPER Niņo-3.4 hindcasts and forecasts (dashedlines) versus observations (solid lines in °C). The dashed vertical line demarks the separation between developmental sample-based hindcasts (on the left) versus independent forecast tests (on the right). Panels display zero through seven season leads - (a) through (g), respectively. Sample-based linear correlation coefficients and RMSE are displayed.
