Influences of a Rough Bottom Topography on Flow Kinematics in an Eddy-Resolving Circulation Model
Publisher: American Meteorological Society
Abstract: The effects of a rough topography are investigated in a primitive equation, eddy-resolving circulation model of an idealized ocean basin. The topography is chosen as a random field with an isotropic spectrum, specified ...
Annual Cycle of Poleward Heat Transport in the Ocean: Results from High-Resolution Modeling of the North and Equatorial Atlantic
Publisher: American Meteorological Society
Abstract: The annual cycle of meridional heat transport in the North and equatorial Atlantic Ocean is studied by means of the high-resolution numerical model that had been developed in recent years as a Community Modeling Effort for ...
Mesoscale Variability in the Atlantic Ocean from Geosat Altimetry and WOCE High-Resolution Numerical Modeling
Publisher: American Meteorological Society
Abstract: Characteristic of the mesoscale variability in the Atlantic Ocean are investigated by analyzing the Geosat altimeter signal between 60°S and 60°N. The rms sea-surface variability for various frequency bands is studied, ...
Eddy Dynamics in a Primitive Equation Model: Sensitivity to Horizontal Resolution and Friction
Publisher: American Meteorological Society
Abstract: A primitive equation model of an idealized ocean basin, driven by simple, study wind and buoyancy forcing at the surface, is used to study the dynamics of mesoscale eddies. Model statistics of a six-year integration using ...
Response of Circulation and Heat Transport in the North Atlantic to Changes in Thermohaline Forcing in Northern Latitudes: A Model Study
Publisher: American Meteorological Society
Abstract: To avoid an explicit simulation of the overflows across the Greenland-Scotland ridge, many models of the large-scale ocean circulation seek to include the net effect of the inflowing dense water masses by restoring temperature ...
Particle Dispersion and Mixing of Conservative Properties in an Eddy-Resolving Model
Publisher: American Meteorological Society
Abstract: We examine the diffusive behavior of the flow field in an eddy-resolving, primitive equation circulation model. Analysis of fluid particle trajectories illustrates the transport mechanisms, which are leading to uniform ...
Multidecadal Changes in Southern Ocean Ventilation since the 1960s Driven by Wind and Buoyancy Forcing
Publisher: American Meteorological Society
Multidecadal Indian Ocean Variability Linked to the Pacific and Implications for Preconditioning Indian Ocean Dipole Events
Publisher: American Meteorological Society
Abstract: AbstractThe Indian Ocean has sustained robust surface warming in recent decades, but the role of multidecadal variability remains unclear. Using ocean model hindcasts, characteristics of low-frequency Indian Ocean temperature ...
Monthly Mean Wind Stress and Sverdrup Transports in the North Atlantic: A Comparison of the Hellerman–Rosenstein and Isemer–Hasse Climatologies
Publisher: American Meteorological Society
Abstract: The monthly mean wind stress climatology of Hellerman and Rosenstein (HR) is compared with the climatology of Isemer and Hasse (IH), which represents a version of the Bunker atlas (BU) for the North Atlantic based on revised ...
