Baroclinic Wave Drag and Barotropic to Baroclinic Energy Transfer at Sills as Evidenced by Tidal Retardation, Seiche Damping and Diapycnal Mixing in Fjords
Fluctuating barotropic flow over sills in stratified water is subjected to baroclinic wave drag and accompanying barotropic to baroclinic energy transfer. In fjords, this process has notable consequences, for instance, tidal retardation across fjord sills, damping of barotropic seiches and enhanced diapycnal mixing in the basin water. These may be computed from simple models only including loca...
متن کاملResponse of Baroclinic Life Cycles to Barotropic Shear
Cyclonic barotropic shear of incrementally increasing magnitude is imposed on an idealized midlatitude jet, and the life cycles of baroclinically unstable wavenumber 6 perturbations growing on these jets are studied. When the barotropic shear parameter passes a critical value, the life cycle makes an abrupt transition from anticyclonic to cyclonic behavior. The abrupt transition in behavior is ...
متن کاملIncoherent Nature of M2 Internal Tides at the Hawaiian Ridge
Moored current, temperature, and conductivity measurements are used to study the temporal variability of M2 internal tide generation above the Kaena Ridge, between the Hawaiian islands of Oahu and Kauai. The energy conversion from the barotropic to baroclinic tide measured near the ridge crest varies by a factor of 2 over the 6-month mooring deployment (0.5–1.1 W m). The energy flux measured ju...
متن کاملNumerical and Analytical Estimates of M2 Tidal Conversion at Steep Oceanic Ridges
Numerical calculations of the rate at which energy is converted from the external to internal tides at steep oceanic ridges are compared with estimates from analytic theories. The numerical calculations are performed using a hydrostatic primitive equation ocean model that uses a generalized s-coordinate system as the vertical coordinate. The model [Regional Ocean Modeling System (ROMS)] estimat...
متن کاملConversion of the Barotropic Tide
Using linear wave theory, the rate at which energy is converted into internal gravity waves by the interaction of the barotropic tide with topography in an ocean is calculated. Bell’s formula for the conversion rate is extended to the case of an ocean of finite depth H with weak two-dimensional topography h(x, y) and arbitrary buoyancy frequency N(z). Approximate solutions are computed using th...
