An Isopycnal View of Near-Boundary Mixing and Associated Flows
Publisher: American Meteorological Society
Abstract: The effectiveness of mixing near a sloping boundary is reduced not just by the ratio of the stratification there to that in the interior but by the square of this ratio. This result has previously been derived and interpreted ...
What is the “Near-Inertial” Band and Why Is It Different from the Rest of the Internal Wave Spectrum?
Publisher: American Meteorological Society
Abstract: The ?near-inertial? part of the internal wave continuum is dominant and also different from the rest of the spectrum. A simple possible reason for the difference is that waves generated at the surface are not reflected or ...
Unexpected Waves
Publisher: American Meteorological Society
Abstract: Extreme, or ?rogue,? waves are those in the tail of the probability distribution and are a matter of great concern and considerable research. They may be partly associated with non-Gaussian behavior caused by resonant ...
On the Body-Force Term in Internal-Tide Generation
Publisher: American Meteorological Society
Abstract: The generation of internal tides can be ascribed to the action of a buoyancy force caused by the flow of the barotropic tide over topographic features. It is commonly assumed that the barotropic flow can be taken as ...
The Signature of Inertial and Tidal Currents in Offshore Wave Records
Publisher: American Meteorological Society
Abstract: he roughness of the sea surface can be affected by strong currents. Here, long records of surface wave heights from buoy observations in the northeastern Pacific Ocean are examined. The data show the influence of tidal ...
An Apparent Surface Buoyancy Flux Associated with the Nonlinearity of the Equation of State
Publisher: American Meteorological Society
Abstract: The temperature dependence of the expansion coefficient of seawater can lead to a nonzero annual-average surface buoyancy flux even if the annual-average heat flux is zero. In the Mediterranean Sea, for example, this effect ...
On a Recent Parameterization of Mesoscale Eddies
Publisher: American Meteorological Society
Abstract: A recent parameterization of mesoscale eddies by Gent and McWilliams (GMc) represents their effects as advective and diffusive fluxes along isopycnals. The form chosen for the added transport velocity due to eddies flattens ...
Mixed Layer Deepening Due to Langmuir Circulation
Publisher: American Meteorological Society
Abstract: The interaction between wind-driven Langmuir circulation and preexisting stratification is examined in order to elucidate its role in the deepening of the ocean surface mixed layer. For linear stratification, a numerical ...
