Spreading of near-inertial energy in a 1/12° model of the North Atlantic Ocean
Near-inertial energy in the ocean is thought to be redistributed by ß-dispersion, whereby near-inertial waves generated at the surface by wind forcing propagate downward and equatorward. In this letter, we examine the spreading of near-inertial energy in a realistic 1/12° model of the North Atlantic...
