Fig. 1: ENSO correlation skill in CTEFNet and other models.
From: Toward long-range ENSO prediction with an explainable deep learning model
The all-season correlation skill of the three-month-moving-averaged Niño 3.4 index as a function of the forecast lead month in CTEFNet (solid orange), CNN(solid deep blue), Geoformer (solid purple), ResCNN (solid green), ResoNet (solid brown), STPNet (solid pink), persistent forecast (dash black) and the dynamical forecast systems included in the NMME project (dash with other colors). The shading around the lines for the DL models denotes the 95% confidence interval, based on the bootstrap method.The validation period is between 1980 and 2021.
