The 1985–2012 North Atlantic (a) Climatological E – P (mm*day−1), (b) correlation between the areal averaged subpolar gyre E-P (red-contoured rectangle in b) and the E-P over the rest of the North Atlantic Ocean, and c) time series of E-P over the subpolar NA (red box in b) and E-P over the subtropical NA (green box in b). Correlations and time series are based on the 1985–1994, 1995–2004, and 2005–2012 monthly climatological E and P fields (N = 36). The red box in (a) designates the subpolar North Atlantic (SPNA) region and the green box designates the subtropical North Atlantic (STNA). Black dotted line in (b) represents the region where correlation is lower than −0.330 (95% CI). This figure was created using the Grid Analysis and Display System (GrADS) software (available at: http://cola.gmu.edu/grads/).
