Buoyancy-Driven Flows
Buoyancy-Driven Flows
2015/7/15
Buoyancy forces, and their interplay with pressure, inertia, and rotation, represent a key ingredient in a wide range of oceanic and atmospheric flow processes. They strongly influence global ocean ci...
A Two-Level Wind and Buoyancy Driven Thermocline Model
Two-Level Wind Buoyancy Driven Thermocline Model
2009/1/16
A simple two-level model is designed to simulate the “thermocline equations,” applicable for large-scale steady oceanic flow. The model serves two functions. First, it replaces problems with the inter...
Wind Effects on the Buoyancy-Driven General Circulation in a Closed Basin Using a Two-Level Model
Buoyancy-Driven Circulation buoyancy fluxes Two-Level Model
2009/1/8
Wind effects on buoyancy-driven circulation in a two-level rectangular basin are studied. The ocean is driven by positive and negative buoyancy fluxes in the northern and southern portions as well as ...
Buoyancy-driven Abyssal Circulation in a Circumpolar Ocean
Abyssal Circulation Circumpolar Ocean Buoyancy-driven
2008/12/22
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 red...
A Model Study of the Buoyancy-Driven Circulation in the Gulf of Maine
Buoyancy-Driven Circulation Gulf of Maine
2008/12/17
A quasi-linear prognostic numerical model has been used to study the three-dimensional baroclinic circulation in the Gulf of Maine region, with a focus on the buoyancy-driven circulation in the inner ...
The Influence of Layer Outeropping on the Separation of Boundary Currents. Part II：The Wind- and Buoyancy-Driven Experiments
Layer Outeropping Wind-and Buoyancy-Driven Experiments Boundary Currents
2008/12/12
It is shown that the main characteristic of the Persons western boundary current separation mechanism, namely a separation south of the zero wind stress curt line (ZWCL), is no longer present when dia...
A Model of Wind-and Buoyancy-Driven Ocean Circulation
Ocean Circulation surface buoyancy flux wind-driven Ekman layer
2008/12/11
A layered model of steady geostrophic ocean circulation driven by wind stress and buoyancy flux at the surface is derived. Potential vorticity, or thickness, of the two near-surface layers is driven b...
Buoyancy-Driven Circulation in an Ocean Basin with Isopycnals Intersecting the Sloping Boundary
potential vorticity Buoyancy-Driven Circulation Ocean Basin Sloping Boundary
2008/12/10
The dynamics that govern the spreading of a convectively formed water mass in an ocean with sloping boundaries are examined using an isopycnal model that permits the interface between the layers to in...
Response Characteristics of a Buoyancy-Driven Sea
Response Characteristics Buoyancy-Driven Sea
2008/7/31
The authors consider the flow in a semienclosed sea, or basin, subjected to a destabilizing surface buoyancy flux and separated from a large adjoining reservoir by a sill. A series of numerical experi...
Dynamics of a Buoyancy-Driven Coastal Jet: The Gaspé Current
Buoyancy-Driven Coastal The Gaspé Current
2008/7/25
A primitive equation ocean model is applied to the process study of the Gaspé Current and cyclonic circulation over the northwestern Gulf of St. Lawrence (NWG). The model is driven by river discharge ...
The Effect of Continental Slope on Buoyancy-Driven Circulation
Effect of Continental Slope Buoyancy-Driven Circulation
2008/7/21
The effect of continental slope on buoyancy-driven circulation has been studied using a two-layer quasigeostrophic model. In the model, buoyancy flux is incorporated as interfacial mass flux, which co...
Numerical Simulations of a Buoyancy-Driven Coastal Countercurrent off Vancouver Island
Numerical Simulations Buoyancy-Driven Coastal Vancouver Island
2008/7/8
A three-dimensional prognostic numerical model has been developed to study the ocean circulation around Vancouver Island, British Columbia. In a series of simulations, the model is applied to examine ...
