A Comparison Study and Software Implementation of NORDA Ocean Models.

Abstract

During the course of this research, three technical areas have been addressed: (i) eddy-meanflow energetics, (ii) model extension to irregular geometries, and (iii) flows around seamounts. In the first area, three models have been developed to study eddy-meanflow energetics in ocean circulation. The formulation of these models is unique and it is felt that they are the first truly applicable to regional energetics. Similarly, NORDA modeling capabilities have been considerably extended by permitting the modelling of irregular ocean basins. This extension from simple rectangular geometries has greatly improved the realism of the model and its behavior. The seamount studies are specifically directed at an examination of measured circulation perturbations near a seamount topography and a comparison with predicted patterns. These comparisons provide data on model ability to predict patterns. These comparisons provided data on model ability to predict flow fields and also on the accuracy of predictions.
