Increased multidecadal variability of the North Atlantic Oscillation since 1781

Nathalie F. Goodkin , Konrad A. Hughen , Scott C. Doney & William B. Curry

The North Atlantic Oscillation is a meridional oscillation of atmospheric mass measured between Iceland and the A|[ccedil]|ores, which drives winter climate variability in eastern North|[nbsp]|America and Europe. A prolonged period of the positive phase during the 1990s led to the suggestion that anthropogenic warming was affecting the behaviour of the North Atlantic Oscillation.
