On the Detection of “Inertial” Waves with Pycnocline Followers
Publisher: American Meteorological Society
Abstract: The vertical displacements associated with oscillations near the local inertial frequency f, in a stratified ocean, are found to be significant, even very close to f. For a frequency, ?=(1+?)f, the ratio of rms vertical ...
The Effect of Current-Induced Stress Perturbation On Baroclinic Rossby Waves in a Continuously Stratified Model
Publisher: American Meteorological Society
Abstract: A shear stress at the air?sea interface is induced by the presence of surface currents. In the case of isotropic wind, a quadratic stress law leads to a stress curl proportional to and opposing the surface current vorticity. ...
The Influence of Layer Outeropping on the Separation of Boundary Currents. Part II: The Wind- and Buoyancy-Driven Experiments
Publisher: American Meteorological Society
Abstract: It is shown that the main characteristic of the Persons western boundary current separation mechanism, namely a separation south of the zero wind stress curt line (ZWCL), is no longer present when diabatic effects are ...
On the Connection between the Mediterranean Outflow and the Azores Current
Publisher: American Meteorological Society
Abstract: As the salty and dense Mediteranean overflow exits the Strait of Gibraltar and descends rapidly in the Gulf of Cadiz, it entrains the fresher overlying subtropical Atlantic Water. A minimal model is put forth in this study ...
Salinity-driven Thermocline Transients in a Wind- and Thermohaline-forced Isopycnic Coordinate Model of the North Atlantic
Publisher: American Meteorological Society
Abstract: An isopycnic-coordinate oceanic circulation model formulated with the aim of simulating thermodynamically and mechanically driven flow in realistic basins is presented. Special emphasis is placed on the handling of diabatic ...
Inclusion of Thermobaricity in Isopycnic-Coordinate Ocean Models
Publisher: American Meteorological Society
Abstract: Buoyancy anomalies caused by thermobaricity, that is, the modulation of seawater compressibility by potential temperature anomalies, underlie a long-standing argument against the use of potential-density-framed numerical ...
