A 2 1/2 dimensional thermohaline circulation model with boundary mixing
… (THC) is developed, assuming that the mixing only occurs near western and eastern boundary layers. When the surface density is prescribed, the climatically important quantities, such as the strength of overturning and meridional heat transport, are related to the zonal integral over the …

A laboratory study of localized boundary mixing in a rotating stratified fluid
Oceanic observations indicate that abyssal mixing is localized in regions of rough topography. How locally mixed fluid interacts with the ambient fluid is an open question. Laboratory experiments explore the interaction of mechanically induced boundary mixing and an interior body of linearly …

Box models of thermohaline circulation
… study the fluid dynamics of locally intensified mixing, referred to as `boundary mixing' within the ocean literature, and also the effect of mixing between the up and downwelling flows on the steady and transient circulation within an idealised filling-box flow. In chapters 2 and 3 we present an …

Transport of fluid from the boundary of a lake
… stratification. A tracer was injected at the boundary of the lake and surveyed on four separate occasions over a period of three days. The Lake number was less than 10 during the first day of the tracer study. Evidence from three approaches supported the existence of V1H1 and V2H1 modes. Three …

Two-Dimensional Lake and Reservoir Modeling: Natural and Plume-Induced Mixing Mechanisms
Lakes and reservoirs exhibit a number of mixing and transport mechanisms. Understanding the transport is crucial to understanding and predicting constituent and density structures. Transport in waterbodies can be natural, such as seiche-induced boundary mixing or advectively-driven inflows. …

Modelling large scale ocean circulation : the role of mixing location and meridional pressure gradients for the Atlantic overturning dynamics
… what are its driving mechanisms: diapycnal mixing and Southern Ocean winds. This work aims at clarifying what sets the strength of the Atlantic overturning components in an ocean general circulation model and discusses the role of spatially inhomogeneous mixing, numerical diffusion and …

The roles of mixing, geothermal heating, and surface buoyancy forcing in ocean meridional overturning dynamics
… scaling behavior, the consequences of diapycnal mixing location, the impact of deep buoyancy fluxes, and the importance of the surface restoring timescale are considered. As required by advective-diffusive balance, upwelling across isopycnals in low latitudes occurs where diapycnal mixing is …
