Eddy-resolving simulations of the Atlantic and Pacific Oceans were performed usin the HYbrid Coordinate Ocean Model (HYCOM at l/120 (-l km mid-latitude) resolution. HYCOM is isopycnal in the open, straqfie ocean, but makes a dynamically smooth transition to a terrain-following coordinate in shallow water and to pressure coordinates in the mixed layer and/or unstratified re ions via the layered continuity e uation. This approach retains the advanta es that each individual vertical coordinate system offers. fter a series offree ‘running sxmdlations, a data assimilative version of the/120 Atlantic HYCOM has been developed into a near real-time nowcast/forecast system. Sea surface height analyses of available satellite altimeter data are assimilated into the model. A nowcast and a 10-day forecast are produced each week Near real-time results are available via the HYCOM consortium for data assimilative ocean …
