The Hybrid Coordinate Ocean Model HYCOM Halliwell et al., 1998, 2000 Bleck, 2001 was developed to address known shortcomings in the vertical coordinate scheme of the Miami Isopycnic-Coordinate Ocean Model MICOM developed by Rainer Bleck and colleagues. HYCOM is a primitive equation, general circulation model with vertical coordinates that remain isopycnic in the open, stratified ocean. However, the isopycnal vertical coordinates smoothly transition to z-coordinates in the weakly stratified upper-ocean mixed layer, to terrain-following sigma coordinates in shallow water regions, and back to z-level coordinates in very shallow water. The latter transition prevents layers from becoming too thin where the water is very shallow. The HYCOM user has control over setting up the model domain, generating the forcing fields, and ingesting either the climatology or output fields from other model simulations to use for boundary and interior relaxation. The model is fully parallelized and designed to be portable among all UNIX-based systems.
