RISFresh Water and Atmospheric Cooling Control on Density-Compensated Overturning in the Labrador Sea
Publisher: American Meteorological Society
Particle Exchange in an Unstable Jet
Publisher: American Meteorological Society
Abstract: A one-dimensional model of baroclinic instability is used to reconcile two differing interpretations on why neutrally buoyant floats cross the Gulf Stream more readily at subthermocline depths. The study compares the ...
On the Source of Mediterranean Overflow Water Property Changes
Publisher: American Meteorological Society
Abstract: A recent study of the eastern North Atlantic detailed significant increases in the temperature and salinity of the Mediterranean Overflow Water (MOW) from 1950 to 2000. To examine the degree to which the source waters, ...
Breaking the Linkage Between Labrador Sea Water Production and Its Advective Export to the Subtropical Gyre
Publisher: American Meteorological Society
Abstract: eep water formation in the northern North Atlantic has been of long-standing interest because the resultant water masses, along with those that flow over the Greenland?Scotland Ridge, constitute the lower limb of the ...
Cross-Frontal Exchange in the Middle Atlantic Bight as Evidenced by Surface Drifters
Publisher: American Meteorological Society
Abstract: Surface drifters at 10 and 40 m are analyzed to assess cross-frontal exchange characteristics within the Middle Atlantic Bight. This Lagrangian analysis shows a shelfbreak jet characterized by strong and ubiquitous meandering. ...
Evaluation of North Atlantic Property Field Simulations at ⅙°
Publisher: American Meteorological Society
Abstract: One way to measure the skill of an ocean general circulation model is to evaluate its ability to simulate observed property distributions. Pressure, temperature, and salinity distributions generated by a ?° Atlantic Ocean ...
On the Linkage between Labrador Sea Water Volume and Overturning Circulation in the Labrador Sea: A Case Study on Proxies
Publisher: American Meteorological Society
Abstract: AbstractAlthough proxies have generally been used to study deep ocean convection and overturning circulation in the Labrador Sea, their efficacy has not been explicitly evaluated because observations that directly measure ...
On the Temporally Varying Northward Penetration of Mediterranean Overflow Water and Eastward Penetration of Labrador Sea Water
Publisher: American Meteorological Society
Abstract: Historical hydrographic data in the eastern North Atlantic are used to suggest a connection between the northward penetration of Mediterranean Overflow Water (MOW) and the location of the subpolar front, the latter of which ...
Potential Vorticity Dynamics of Boundary Currents in a Quasi-geostrophic Ocean
Publisher: American Meteorological Society
Abstract: Boundary layer potential vorticity dynamics for a quasi-geostrophic, eddy-resolving general circulation ocean model are studied using both Lagrangian and Eulerian analyses. Active western boundary layers are found not only ...
The Influence of Topography on the Stability of Shelfbreak Fronts
Publisher: American Meteorological Society
Abstract: In an attempt to understand the degree to which the stability of a shelfbreak front, characterized by continuous horizontal and vertical shear, is affected by topography, a linear stability analysis was conducted for a ...
