Subinertial tides and mixing at the Mendocino Ridge

At a latitude of 44N, interactions of the diurnal and semidiurnal surface tides at the Mendocino Ridge elicit distinct baroclinic responses. The diurnal tide in this region is subinertial, meaning that internal tides are trapped to topography, while the superinertial semidiurnal constituents can freely radiate. The interaction of tidal constituents at the ridge lead to tidal lee waves during certain phases of the tide, which are associated with turbulence and mixing.
