1/32/spl deg/ global ocean modeling and prediction

This DoD HPC challenge project is a crucial component of an effort to develop a data-assimilative 1/32/spl deg/ global ocean nowcast/forecast system, which includes the associated basic research and exploratory development. The need for 1/32/spl deg/ resolution (/spl sim/3.5 km at midlatitudes) has been demonstrated through extensive research, including essential contributions from our FY97 and FY98-00 DoD HPC Challenge projects. The ocean model, after 30 years of climatological spinup, was run interannually spanning the period 1979-present. Data assimilation experiments are currently underway. Transition of this system to operational use at the Naval Oceanographic Office (NAVO) is planned.
