Web20 de jun. de 2016 · This study suggests that variations in the North Atlantic Oscillation (NAO) can drive multidecadal climate variability over the Northern Hemisphere, including rapid Arctic sea ice loss and multidecadal changes in Atlantic tropical storm activity. NAO is related to the strength of the westerly winds in the subpolar North Atlantic.
