Abstract: A theory for the observed interleaving of water masses at the equator is presented. Unlike layers at midlatitudes, individual layers are observed to be coherent over horizontal scales of hundreds of kilometers. To allow ...

Abstract: The effect of a depth-limited bottom boundary layer on the stability of a baroclinic zonal current is investigated. The model is of a two-layer quasi-geostrophic flow. Limiting the height of the boundary layer introduces ...

Abstract: A second-order turbulence closure model is used to study the development of the benthic boundary layer. Results are presented on the effects of a time-dependent oscillatory forcing flow and an initially stably stratified ...

Abstract: The interaction between a bottom mixed layer and a mesoscale eddy field is studied using a numerical model of a two-layer quasi-geostrophic fluid above a mixed layer. The height of the mixed layer is assumed to be restricted ...

Abstract: The jet structure of the Antarctic Circumpolar Current (ACC) simulated by two general circulation models (GCMs), FRAM (Fine Resolution Antarctic Model) and POP (Parallel Ocean Program), is examined in relation to the bottom ...

Abstract: A stateoftheart spray modeling methodology is presented. Key features of the methodology, such as adaptive mesh refinement (AMR), advanced liquid–gas momentum coupling, and improved distribution of the liquid phase, are ...

Abstract: The dispersion of a tracer by a two-dimensional gyre circulation is studied using simple numerical models. Two approaches are taken: a random walk model formulated in a streamline coordinate system and the numerical solution ...

Abstract: High levels of diapycnal mixing and geothermal heating near midocean ridges contribute to the buoyancy fluxes that are required to close the global circulation. In topographically confined areas, such as the deep median ...

Abstract: The dynamics of the Southern Ocean have been studied using two high-resolution models, namely the Fine Resolution Antarctic Model (FRAM) and the Parallel Ocean Program (POP) model. Analysis of these models includes zonal ...
