Control of Bering Strait Transport by the Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: It is well established that the mean transport through Bering Strait is balanced by a sea level difference between the North Pacific and the Arctic Ocean, but no mechanism has been proposed to explain this sea level ...
Ventilation of Eastern Subtropical Gyres
Publisher: American Meteorological Society
Abstract: A simple mechanism for the generation of flow in the eastern region of the oceans is presented. It is shown that even a small amount of upwelling-favorable wind stress parallel to the boundary makes the subducted geostrophic ...
Regimes of Thermocline Scaling: The Interaction of Wind Stress and Surface Buoyancy
Publisher: American Meteorological Society
Abstract: The role of the relative geometry of mechanical forcing (wind stress) and buoyancy forcing (prescribed surface temperature) in the maintenance of the main thermocline is explored. In particular, the role of the wind stress ...
Convective Adjustment and Thermohaline Excitability
Publisher: American Meteorological Society
Abstract: Welander's flip?flop model exhibits oscillations when forced by stochastic white noise (with zero mean) even in the region of parameters where the deterministic system has a globally stable fixed point. Perturbations away ...
A Stratified Model of the Inertial Recirculation
Publisher: American Meteorological Society
Abstract: An inertial gyre with characteristics very similar to the recirculation observed in eddy-resolving general circulation models is obtained with a simple, analytically tractable, two-layer model. The recirculating gyre is ...
Thermal Feedback on Wind Stress as a Contributing Cause of Climate Variability
Publisher: American Meteorological Society
Abstract: A model that isolates the interaction between midlatitude ocean gyres and the wind stress due to atmospheric baroclinic eddies is formulated. The ocean and atmosphere are coupled through their respective heat balances and ...
On the Role of Topography in the Ocean Circulation: Diffusive and Inertial Effects
Publisher: American Meteorological Society
Abstract: In an earlier paper it was shown that the presence of bottom topography can substantially alter the Sverdrup prediction for the large-scale wind driven flow. In their model the abyssal water is set in motion by the eddy ...
Angular Momentum and Temperature Homogenization in the Symmetric Circulation of the Atmosphere
Publisher: American Meteorological Society
Abstract: The axisymmetric model of the Hadley circulation can be systematically reduced in the limit of small Rossby number to a simpler one-dimensional system. The reduced system governs the nonlinear evolution of the surface ...
An Energy-Constrained Parameterization of Eddy Buoyancy Flux
Publisher: American Meteorological Society
Abstract: A parameterization for eddy buoyancy fluxes for use in coarse-grid models is developed and tested against eddy-resolving simulations. The development is based on the assumption that the eddies are adiabatic (except near ...
The Potential Role of Bering Strait in the Dynamics of Multidecadal Variability in the North Atlantic: An Idealized Model Study
