Formulation of the NRL Layered Ocean Model in Spherical Coordinates.
Abstract
This report describes NRL's hydrodynamic (isopycnal) nonlinear, primitive equation, ocean circulation model in a spherical layer suitable for a large basin or the global domain. This document should be read in conjunction with NOARL Report 35, December 1991, The Navy Layered Ocean Model User's Guide 25. Spherical geometry requires careful treatment of the equations of fluid dynamics to ensure spurious terms are not introduced during the layer averaging process, particularly in the momentum diffusion expressions. From these layer averaged equations, finite difference approximations are derived on a grid of uniform intervals in longitude and latitude (not necessarily the same). These equations may be solved efficiently on modern architecture scientific computers, allowing accurate description of ocean flows.
