Extended Data Fig. 5: Temporal correlations among the interannual variability of AMOC, fingerprint indices and E−P.
From: Weakening Atlantic overturning circulation causes South Atlantic salinity pile-up
a–c,Cross-model scatter plot of the temporal correlations between the annual mean AMOC and TNA versus those between AMOC and SN (a), (E−P)S and SS versus AMOC and SS (b) and (E−P)N and SN versus AMOC and SN (for comparison with ‘S’ in b, here ‘N’ represents the difference of North Atlantic with North Pacific) for the historical period (1861–2018 with 2006–2018 from the RCP8.5 simulation) (c). In each panel, the average of the correlations is shown by open black circles and the correlation of the cross-model ensemble mean is shown in in filled black circles. The grey lines in each panel denote the P > 0.1 significance level (against a white noise with sample size n = 158, one-tailed test). A scatter plot similar to that in a for AMOC and TNA versus AMOC and SS is shown in Fig. 3b.
