Downwelling in Basins Subject to Buoyancy Loss
Publisher: American Meteorological Society
Abstract: ecent observational, theoretical, and modeling studies all suggest that the upper part of the downwelling limb of the thermohaline circulation is concentrated in strong currents subject to buoyancy loss near lateral ...
A New Parameterization for Entrainment in Overflows
Publisher: American Meteorological Society
Abstract: Dense overflows entrain surrounding waters at specific locations, for example, sills and constrictions, but also along the descent over the continental slope. The amount of entrainment dictates the final properties of these ...
Laboratory Experiments on the Interaction of a Buoyant Coastal Current with a Canyon: Application to the East Greenland Current
Publisher: American Meteorological Society
Abstract: This paper presents a set of laboratory experiments focused on how a buoyant coastal current flowing over a sloping bottom interacts with a canyon and what controls the separation, if any, of the current from the upstream ...
The Dispersal of Dense Water Formed in an Idealized Coastal Polynya on a Shallow Sloping Shelf
Publisher: American Meteorological Society
Abstract: his study examines the dispersal of dense water formed in an idealized coastal polynya on a sloping shelf in the absence of ambient circulation and stratification. Both numerical and laboratory experiments reveal two ...
Impact of Two Plumes’ Interaction on Submarine Melting of Tidewater Glaciers: A Laboratory Study
Publisher: American Meteorological Society
Abstract: dealized laboratory experiments investigate the glacier?ocean boundary dynamics near a vertical glacier in a two-layer stratified fluid. Discharge of meltwater runoff at the base of the glacier (subglacial discharge) ...
Impact of a Localized Source of Subglacial Discharge on the Heat Flux and Submarine Melting of a Tidewater Glacier: A Laboratory Study
Publisher: American Meteorological Society
Abstract: dealized laboratory experiments have been conducted in a two-layer stratified fluid to investigate the leading-order dynamics that control submarine melting and meltwater export near a vertical ice?ocean interface as a ...
Laboratory Experiments on Eddy Generation by a Buoyant Coastal Current Flowing over Variable Bathymetry
Publisher: American Meteorological Society
Abstract: Irminger rings are warm-core eddies formed off the west coast of Greenland. Recent studies suggest that these eddies, which are implicated in the rapid springtime restratification of the Labrador Sea, are formed by an ...
A Geostrophic Adjustment Model of Two Buoyant Fluids
Publisher: American Meteorological Society
Abstract: combination of analytical calculations and laboratory experiments has been used to investigate the geostrophic adjustment of two buoyant fluids having different densities in a third denser ambient fluid. The frontal position, ...
Interaction between a Vertical Turbulent Jet and a Thermocline
Publisher: American Meteorological Society
Abstract: he behavior of an axisymmetric vertical turbulent jet in an unconfined stratified environment is studied by means of well-resolved, large-eddy simulations. The stratification is two uniform layers separated by a thermocline. ...
Entrainment in a Dense Current Flowing Down a Rough Sloping Bottom in a Rotating Fluid
Publisher: American Meteorological Society
Abstract: ense oceanic overflows descend over the rough topography of the continental slope entraining and mixing with surrounding waters. The associated dilution dictates the fate of these currents and thus is of fundamental ...
