Fig. 1: The Atlantic Niño variability and prediction skill.
From: Decline in Atlantic Niño prediction skill in the North American multi-model ensemble
a 15-year sliding standard deviations (STD) of ATL3 index calculated separately with the HadISST and ERSSTv5 datasets. b ACCs of the multiple-model ensemble mean (MME) over the two subperiods. c Persistence prediction skills over the two subperiods. The x-axis of (a) indicates the last year of each 15-year sliding window. Error bars in (b) and (c) indicate the 95% confidence interval determined by a bootstrap test with resampling times of 10000.
