Fig. 1: Circulation of the subpolar North Atlantic.
From: Decadal changes in Atlantic overturning due to the excessive 1990s Labrador Sea convection
Snapshot of surface speed in the high-resolution model VIKING20X, illustrating the meandering flow of the North Atlantic Current and the narrow boundary current emerging south of the Denmark Strait along the eastern continental shelf of Greenland. Shaded in grey is the area where convection exceeded 1800 m depth during the winters of 1990–1994. The black lines indicate the trans-Atlantic transport sections denoted SILL (dotted), FULL (solid), and its eastern portion EAST (dashed), as well as 48N (dashdot). The blue frame encloses the area for which the annually repeated heat flux is applied in experiment SENS. The black frame denotes the area of averaging for the water mass properties shown in Fig. 2.
