ROMS Framework and Algorithms

The typical annual overview of ROMS framework and algorithms will be presented. This year the emphasis will be on nesting, model coupling, and the recently released version 3.0. The structural F90 design of ROMS allows three types of nesting topologies: grid refinement, mosaic grids (contact through a boundary), and composed grids (superposition). Model coupling in ROMS is now possible with either the MCT or ESMF libraries. Tight coupling is very trivial with the MCT library but very difficult or impossible with the ESMF library. The pros and cons of ESMF coupling will be discussed.
