During the past five to ten years, a broad partnership of institutions under NOPP sponsorship has collaborated in developing and demonstrating the performance and application of eddy-resolving, real-t...
A nonhydrostatic, isopycnal-coordinate ocean model for internal waves
Nonhydrostatic model Isopycnal coordinates Multi-layer model Internal waves Solitary waves Ocean modeling
2015/6/30
We present a nonhydrostatic ocean model with an isopycnal (density-following) vertical coordinate system. The primary motivation for the model is the proper treatment of nonhydrostatic dispersion and ...
Initial Testing of a Numerical Ocean Circulation Model Using a Hybrid (Quasi-Isopycnic) Vertical Coordinate
Initial Testing Hybrid (Quasi-Isopycnic) Vertical Coordinate Numerical Ocean Circulation Model
2009/2/9
An ocean circulation model, developed for the study of mesoscale to gyre-scale circulation and heat transport, is described and tested. The model employs density as vertical coordinate except in the i...

Quasi-linear Eddy-Viscosity Model for the Flux of Energy and Momentum to Wind Waves Using Conservation-Law Equations in a Curvilinear Coordinate System
Curvilinear Coordinate System Quasi-linear Eddy-Viscosity Model
2008/12/22
The airflow above ocean waves is calculated using a quasi-linear model—one in which the effect of the waves on the mean flow is taken into account. The model uses curvilinear coordinates, in which one...
