Effects of a Concave Bottom Geometry on the Upwelling-driven Circulation in an Abyssal Ocean Basin
Publisher: American Meteorological Society
Abstract: Bottom water circulation in a bowl-shaped, or concave, abyssal basin driven by upwelling is investigated using a simple numerical model. In a basin wholly contained in one hemisphere, the concave bottom geometry introduces ...
Establishment of Deep Ocean Circulation Driven by Deep-Water Production
Publisher: American Meteorological Society
Abstract: A linear, two-layer baroclinic model of deep circulation driven by deep water production is formulated. In distinction to the Stommel-Arons model where a uniform middepth upwelling is prescribed, the present model determines ...
Spinup of Source-driven Circulation in an Abyssal Basin in the Presence of Bottom Topography
Publisher: American Meteorological Society
Abstract: Spinup of the circulation driven by an inflow into an abyssal basin containing a simple large-scale topographic feature is studied, using an inverted one-and-a-half-layer shallow-water model. Two types of topography, one ...
On the Transformation of a Tropical Easterly Wave into a Tropical Depression: A Simple Numerical Study
Publisher: American Meteorological Society
Abstract: Through the time integration of a simple numerical model, the transfomation of a tropical easterly wave into a tropical depression was investigated. The initial condition selected for the model is a slowly decaying adiabatic ...
Comparisons of Localized Convection due to Localized Forcing and to Preconditioning
Publisher: American Meteorological Society
Abstract: Although observations indicate that localization of deep convection results from oceanic preconditioning and only to a lesser extent from the gradients in the atmospheric forcing, most laboratory and numerical simulations ...
Effects of Wind on Convection in Strongly and Weakly Baroclinic Flows with Application to the Labrador Sea
Publisher: American Meteorological Society
Abstract: Large buoyancy loss driving deep convection is often associated with a large wind stress that is typically omitted in simulations of convection. Here it is shown that this omission is not justified when overturning occurs ...
Effects of Wind on Convection in Strongly and Weakly Baroclinic Flows with Application to the Labrador Sea
Publisher: American Meteorological Society
Abstract: Large buoyancy loss driving deep convection is often associated with a large wind stress that is typically omitted in simulations of convection. Here it is shown that this omission is not justified when overturning occurs ...
Idealized Models of Slantwise Convection in a Baroclinic Flow
Publisher: American Meteorological Society
Abstract: Intermediate, or deep, convection in a baroclinic flow occurs along slanted paths parallel to the alongflow absolute momentum surfaces. These surfaces are principally tilted due to the vertical shear in velocity but can ...
A Simple Model of Mass-driven Abyssal Circulation over a General Bottom Topography
Publisher: American Meteorological Society
Abstract: The classic Stommel?Arons problem is revisited in the context of a basin with a general bottom topography containing an equator. Topography is taken to be smoothly varying and, as such, there are no vertical side walls in ...
