Development and Utilization of Regional Oceanic Modeling System (ROMS) & Delicacy, Imprecision, and Uncertainty of Oceanic Simulations: An Investigation with ROMS

Our long-term goal is the continuing evolution of the Regional Oceanic Modeling System (ROMS) as a multi-scale, multi-process model and its utilization for studying a variety of oceanic phenomena. The dynamical processes span a range from turbulence to basin-scale circulation. A complementary goal is to explore, document, and explain the nature of the delicacies of the simulations for highly turbulent oceanic circulation. We expect that our experience will be relevant to analysis and forecast uncertainties for other atmospheric and oceanic simulation models. These activities are of interest to ONR through its core, DRI, and NOPP programs, including submesoscale parameterization (AESOP), strong internal waves (NLIWI), high-resolution air-sea interaction (HIRES), tropical cyclones, sediment transport, and horizontal mixing (LATMIX).
