Resonance of Fofonoff's Mode in a Rotated Basin
Publisher: American Meteorological Society
Abstract: Fofonoff solutions to the inviscid barotropic potential vorticity equation are found for the steady, free flow in a basin rotated at an arbitrary angle to a latitude circle. These solutions am used to study the inertial ...
Topographic Steering of the Antarctic Circumpolar Current
Publisher: American Meteorological Society
Abstract: An analytic model of the Antarctic Circumpolar Current (ACC) is presented in which information contained in a hydrographic section is propagated along characteristics. The characteristics are obtained by assuming that ...
Influence of Topography on the Large-Scale Ocean Circulation
Publisher: American Meteorological Society
Abstract: The influence of the bottom topography on the large-scale ocean circulation is discussed and illustrated with a simple model based on the ideal-fluid thermocline equations. The requirement that fluid remains in linear ...
Zonal Penetration Scale of Midlatitude Oceanic Jets
Publisher: American Meteorological Society
Abstract: It is shown that subtle changes in the velocity profile across the seaward extension of midlatitude jets, such as the Gulf Stream, can lead to dramatic changes in the zonal-penetration scale. In particular, if α = dq/d? > ...
On the Thermodynamics of Subduction
Publisher: American Meteorological Society
Abstract: The thermodynamic processes attendant on the transfer of fluid between a surface mixed layer and a stratified thermocline beneath are discussed. For a parcel of fluid in the mixed layer to pass into the stratified ...
Vertical Fluxes of Potential Vorticity and the Structure of the Thermocline
Publisher: American Meteorological Society
Abstract: A new framework for understanding the vertical structure of ocean gyres is developed based on vertical fluxes of potential vorticity. The key ingredient is an integral constraint that in a steady state prohibits a net flux ...
Do We Require Adiabatic Dissipation Schemes in Eddy-Resolving Ocean Models?
Publisher: American Meteorological Society
Abstract: Use of horizontal diffusion of temperature and salinity in numerical ocean models causes spurious diapycnal transfers?the ?Veronis effect??leading to erosion of the thermocline and reduced poleward heat transports. The ...
Vertical Eddy Energy Fluxes in the North Atlantic Subtropical and Subpolar Gyres
Publisher: American Meteorological Society
Abstract: ddy energy generation and energy fluxes are examined in a realistic eddy-resolving model of the North Atlantic. Over 80% of the wind energy input is found to be released by the generation of eddies through baroclinic ...
A Conceptual Model of Ocean Heat Uptake under Climate Change
Publisher: American Meteorological Society
Abstract: conceptual model of ocean heat uptake is developed as a multilayer generalization of Gnanadesikan. The roles of Southern Ocean Ekman and eddy transports, North Atlantic Deep Water (NADW) formation, and diapycnal mixing in ...
Propagation of Meridional Circulation Anomalies along Western and Eastern Boundaries
Publisher: American Meteorological Society
Abstract: otivated by the adjustment of the meridional overturning circulation to localized forcing, solutions are presented from a reduced-gravity model for the propagation of waves along western and eastern boundaries. For wave ...
