The Gent–McWilliams Skew Flux

This paper formulates tracer stirring arising from the Gent–McWilliams (GM) eddy-induced transport in terms of a skew-diffusive flux. A skew-diffusive tracer flux is directed normal to the tracer gradient, which is in contrast to a diffusive tracer flux directed down the tracer gradient. Analysis of the GM skew flux provides an understanding of the physical mechanisms prescribed by GM stirring,...

Adaptive Combination of Behaviors in an gent

Agents are of interest mainly when confronted with complex tasks. We propose a methodology for the automated design of such agents (in the framework of Markov Decision Processes) in the case where the global task can be decomposed into simpler -possibly concurrentsub-tasks. This is accomplished by automatically combining basic behaviors using Reinforcement Learning methods. The main idea is to ...

2 Overview of A GENT S CAPE

Virtual environments have a variety of uses, ranging from entertainment to simulation of hard-to-create environments for training and testing purposes. A common feature of virtual environments, especially those aimed at entertainment, is the presence of virtual entities we call agents, characters or objects in the virtual world possessing human characteristics and able to interact pro-actively ...

The Gent–McWilliams parameterization: 20/20 hindsight

It has now been 20 years since the Gent and McWilliams paper on ‘‘Isopycnal Mixing in Ocean Circulation Models” was published in January 1990 issue of the Journal of Physical Oceanography. That paper was highlighted at the CLIVAR Working Group on Ocean Model Development ‘‘Workshop on Ocean Mesoscale Eddies” which was held at the UK Meteorological Office in April 2009, and this review paper is b...
