Figure 6: Sensitivity experiment.
From: Atlantic multi-decadal oscillation covaries with Agulhas leakage
(a) AMO index in the INALT01 hindcast (black) and HadISST (red, as in Fig. 4). (b) North Atlantic (including Arctic Ocean, as in ref. 30) heat content anomaly in the INALT01 hindcast, integrated between 0–700 m (black) and 200–700 m (blue) and from observations (0–700 m)30 (red shading denotes the observational error). (c) North Atlantic heat content in INALT01 repeated-year forcing experiments: black reference, red (0–700 m) and blue (200–700 m) the sensitivity experiment with artificially isolated increase in Agulhas leakage. All experiments were linearly detrended using the repeated-year forcing experiment.
