Baroclinic Instability in Drake Passage
Publisher: American Meteorological Society
Abstract: A linearized baroclinic instability model is applied to the Drake Passage area. The predictions of the model are found to be in good agreement with observations. Temporal and spatial scales are predicted accurately and the ...
On the Alongshelf Evolution of an Idealized Density Front
Publisher: American Meteorological Society
Abstract: Observations reveal a strong tendency for fronts to locate over the outer continental shelf and the upper portions of the continental slope. In this paper, we consider a model of the alongshelf evolution of a quasi-steady ...
An Equation of State for Use in Ocean Models: Eckart’s Formula Revisited
Publisher: American Meteorological Society
Abstract: Approximate formulas for in situ density as a function of potential temperature, salinity, and pressure are determined for use in numerical models. The approach taken is similar to that of Mellor, but use of the Tumlirz ...
Interpretations of the JEBAR Term
Publisher: American Meteorological Society
Abstract: In diagnostic calculations of the ocean's circulation, the so-called JEBAR (joint effect of baroclinicity and relief) term may induce a significant depth-average current field, as has been noted in the oceanographic ...
Buoyancy-driven Abyssal Circulation in a Circumpolar Ocean
Publisher: American Meteorological Society
Abstract: Simple models are developed to describe the abyssal circulation in a circumpolar ocean driven by localized annual sources of water representing convection events. Models are based on a geostrophic reduced-gravity formulation ...
A Zonally Averaged Ocean Model for the Thermohaline Circulation. Part I: Model Development and Flow Dynamics
Publisher: American Meteorological Society
Abstract: A two-dimensional latitude?depth ocean model is developed on the basis of the zonally averaged balance equations of mass, momentum, heat, and salt. Its purpose is to investigate the dynamics and variability of the ...
A Zonally Averaged Ocean Model for the Thermohaline Circulation. Part II: Interocean Circulation in the Pacific-Atlantic Basin System
Publisher: American Meteorological Society
Abstract: The zonally averaged, latitude-depth ocean model, developed in Part I, is extended to a two-basin system representing the Atlantic and Pacific. Steady states are calculated under two different surface boundary conditions ...
Internal Tide Generation over Topography: Experiments with a Free-Surface z-Level Ocean Model
Publisher: American Meteorological Society
Abstract: A three-dimensional, z-level, primitive-equation ocean circulation model (DieCAST) is modified to include a free-surface and partial cells. The updating of free-surface elevation is implicit in time so that the extra ...
