The Fleet Numerical Oceanography Center Suite of Oceanographic Models and Products

Abstract Fleet Numerical Oceanography Center (FLENUMOCEANCEN) is the navy's real-time prediction center for global-scale and open-ocean regional-scale oceanographic products, having filled this role for over 25 years. FLENUMOCEANCEN provides operational oceanographic services to U.S. and allied naval forces, other components of the Department of Defense, and a wide variety of civilian interests with output from sophisticated ocean models. These models are highly automated and most are linked closely to atmospheric models. Thermal structure and circulation models provide a representation of the three-dimensional mass and current structure on global coarse-resolution grids and regional eddy-resolving grids. Primary attention is focused on nowcasting ocean thennal structure using optimum interpolation analysis of ship, buoy, hathy, and satellite data. In addition, ocean feature models and synthetic subsurface data are used in conjunction with surface front and eddy locations, inferred primarily from satellit...
