Fig. 3: Relationship between the Atlantic Niño prediction skill and ENSO-SAOD correlation.
From: Decline in Atlantic Niño prediction skill in the North American multi-model ensemble

Scatter plots of ATL3 prediction skills against ENSO-SAOD correlations over the two subperiods for predictions at a 0, b 1, c 2, d 3, e 4, f 5 lead months. Blue and red markers indicate prediction skills pre- and post-2000, respectively. Blue and red dashed lines indicate the observed ENSO-ATL3 correlations pre- and post-2000, respectively.
