Surface Forcing of Potential Vorticity in a Numerical Model

Mode water formation has long been treated as a buoyancy flux problem; however this approach fails to explain all of the variability of mode water. A number of different approaches have been demonstrated to explain more of this variability, such as links to North Atlantic Oscillation and the Gulf St...
