RISWave-Forced Barotropic Currents
Publisher: American Meteorological Society
Abstract: Waves rolling in to shallow seas will start to dissipate as a result of the bottom friction. The wave momentum will decrease from the dissipation process, and there is a transfer of momentum that accelerates an Eulerian ...
The Thermohaline Circulation and Vertical Mixing: Does Weaker Density Stratification Give Stronger Overturning?
Publisher: American Meteorological Society
Abstract: The possibility that a decreased equator-to-Pole surface density difference could imply stronger rather than weaker thermohaline circulation (THC) is explored theoretically as well as with the aid of numerical simulations. ...
Observations of Turbulence Caused by a Combination of Tides and Mean Baroclinic Flow over a Fjord Sill
Publisher: American Meteorological Society
Abstract: his study investigates the dissipation rates and flow conditions at the Dr?bak Sill in the Oslofjord. The area was transected 13 times with a free-falling microstructure shear probe during 4 days in June 2011. At the same ...
Stokes Drift in Internal Equatorial Kelvin Waves: Continuous Stratification versus Two-Layer Models
Publisher: American Meteorological Society
Abstract: he Stokes drift in long internal equatorial Kelvin waves is investigated theoretically for an inviscid fluid of constant depth. While the Stokes drift in irrotational waves is positive everywhere in the fluid, that is, ...
Tidal energy loss, internal tide radiation, and local dissipation for two-layer tidal flow over a sill
Publisher: American Meteorological Society
Abstract: simple analytical model for tidal energy loss at fjord sills and its partitioning into local dissipation and radiated internal tides is presented. The analytical model builds on a two-layer assumption with quasi-steady ...
Eulerian versus Lagrangian Approaches to the Wave-Induced Transport in the Upper Ocean
Publisher: American Meteorological Society
Abstract: It is demonstrated that the Eulerian and the Lagrangian descriptions of fluid motion yield the same form for the mean wave-induced volume fluxes in the surface layer of a viscous rotating ocean. In the Eulerian case, the ...
A Quasi-Eulerian, Quasi-Lagrangian View of Surface-Wave-Induced Flow in the Ocean
Publisher: American Meteorological Society
Abstract: In this study the influence of surface waves on the mean flow in an ocean of arbitrary depth is examined. The wave-induced forcing on the mean flow is obtained by integrating the Eulerian equations for mass and momentum ...
On the Variability in the Onset of the Norwegian Coastal Current
Publisher: American Meteorological Society
Abstract: AbstractA high-resolution reanalysis of the circulation in the Kattegat and Skagerrak is used to investigate the mechanisms that control the variability in the onset of the Norwegian Coastal Current. In the reanalysis, the ...
Enhanced Turbulence Associated with the Diurnal Jet in the Ocean Surface Boundary Layer
Publisher: American Meteorological Society
Abstract: etailed observations of the diurnal jet, a surface intensification of the wind-driven current associated with the diurnal cycle of sea surface temperature (SST), were obtained during August and September 2012 in the ...
