On the role of the ocean in projected atmospheric stability changes in the Atlantic polar low region
The occurrence of destructive mesoscale 'polar low' cyclones in the subpolar North Atlantic is projected to decline under anthropogenic change, due to an increase in atmospheric static stability. This letter reports on the role of changes in ocean circulation in shaping the atmospheric sta...
