Global Ocean Prediction Using HYCOM
Abstract
The Hybrid Coordinate Ocean Model (HYCOM) is isopycnal in the open, stratified ocean, but uses the layered continuity equation to make a dynamically smooth transition to a terrain-following coordinate in shallow coastal regions, and to z-level coordinates in the mixed layer and/or unstratified seas. The hybrid coordinate extends the geographic range of applicability of traditional isopycnic coordinate circulation models toward shallow coastal seas and unstratified parts of the world ocean. The principal goal of this DoD Challenge project is to provide a near real time depiction of the three-dimensional global ocean state at fine resolution. On a 7km (mid-latitude) grid, HYCOM has sufficient resolution to provide a baseline depiction of the most of the world's coastal areas, and will be the highest horizontal resolution world's wide source for realistic offshore boundary conditions for realistic offshore boundary conditions for nested coastal models.
