Extension of the Navy Layered Ocean Model to Shallow Seas: A Hybrid Coordinate Approach
1998
Bleck, Rainer
This work extends the geographic range of applicability of isopycnic coordinate circulation models, such as the Miami Isopycnic Coordinate Ocean Model and the Navy Layered Ocean Model, toward shallow coastal seas and unstratified parts of the world ocean. The numerical innovation making this extension possible is the "hybrid" (mixed isopycnic/terrain following) vertical coordinate. (a) Demonstrate the feasibility of the hybrid coordinate approach in an ocean basin encompassing both deep and shallow regions, as well as an annual heating/cooling cycle. Take advantage of the high near-surface vertical resolution afforded by this coordinate in developing alternatives to the Kraus-Turner mixed-layer formulation used in present-day isopycnic models. (b) Port the algorithm to the NLOM.
