Fig. 3: Annual mean ocean to atmosphere heat flux (W/m2) and barotropic stream function (Sv).

A Pre-Industrial annual mean ocean to atmosphere heat flux (W/m2). The 0.15 isoline shows the contour of the annual 15% sea-ice concentration (B) 27.7–26.6 ka BP annual mean ocean to atmosphere heat flux (W/m2). C 26.7–26.6 ka BP barotropic stream function (Sv) with 0–106 m currents overlaid.
