Extended Data Fig. 5: Correlations between AMV/AMM and Sahel rainfall and VWS in preindustrial and historical runs (1950–2014).
From: Tropical Atlantic multidecadal variability is dominated by external forcing
a, joint distribution of correlations between the AMV and VWS (y-axis) and Sahel rainfall (x-axis) in preindustrial runs (N = 3100) and observation (red star). b, as in a but for AMM. c, as in b but for historical runs (with forced response included in single realizations). Comparing panel a and b shows the AMM has a better correlation with Sahel rainfall and VWS than AMV. Similar conclusion could also be drawn by comparing panel c and Fig. 2e. Comparing panel c and Fig. 4b shows the shift of observation before and after 1950. The small purple stars under the big red star are correlations calculated using different datasets, so the red start is the average of the purple stars. See methods how the correlations are calculated.
