Extended Data Fig. 3: Intergyre exchange flow and the transport decompositions into western and eastern basins at 45°N in 1° resolution experiments.
From: Wind-steered Eastern Pathway of the Atlantic Meridional Overturning Circulation
The left column is the zonal sections of the meridional velocity (color, in cm/s) and σ2 isopycnals (lines) in the intergyre boundary; the middle column is the zonally integrated meridional velocity across the basin (\({\int }_{{X}_{W}}^{{X}_{E}}{vdx},\) black), the western basin (\({\int }_{{X}_{W}}^{30W}{vdx},\) blue) and the eastern basin (\({\int }_{30W}^{{X}_{E}}{vdx},\) red), with XW and XE being the western and eastern margins; the right column is the southward (dots) and northward (circles) velocity averaged across the basin (black), the western basin (blue) and the eastern basin (red). (a–c) CTRL_R1 in 1° resolution. (d–f) NoWind_R1 in 1° resolution. (g–i) FB_R1. The isopycnal interval is 0.2 kg/m3 for the dashed lines and is 0.05 kg/m3 for the solid lines. The purple lines indicate the mid-depth isopycnal. The yellow lines indicate the intergyre communication window.
