The origin of the decadal variability in the North Atlantic Ocean is investigated in a series of coupled and ocean-only numerical experiments. Two versions of the IPSL-CM5A model are considered, differing only by their atmospheric horizontal resolution (3.75 degrees x1.87 degrees and 2.5 degrees x1....
