Figure 4. Model analyses of the coherence between North Icelandic SST and SSS variability and North Atlantic circulation.

Correlation between annual North Icelandic SSTs against (a) barotropic stream function and (c) overturning stream function, and SSS against (b) barotropic stream function and (d) overturning stream function, in the North Atlantic derived from an ensemble CMIP5 preindustrial control simulation. The solid black lines show the time-mean stream functions.
