The Coupled Northwest Atlantic Prediction System (CNAPS) is a three-dimensional marine environment nowcast and forecast model developed by the Ocean Observing and Modeling Group. This fully coupled ocean circulation, wave, and atmosphere modeling system predicts conditions over a wide area of the coastal northwest Atlantic Ocean on a daily basis. The model domain covers from the eastern edge of Nova Scotia to the north coast of Venezuela, including the Gulf of Maine, Middle Atlantic Bight, South Atlantic Bight, Gulf of Mexico, Caribbean Sea, and western Sargasso Sea.
Maps of model-generated regional dynamics are organized into three sections:
Virtual Oceanographer allows users to take on the role of oceanographer, by collecting model-generated data. User-defined inquires include virtual transect (subsurface temperature, salinity, and velocity plots), virtual sounding (temperature and salinity profiles), and 72 hour particle trajectory prediction (Lagrangian drifters).
Model Validation presents observational data alongside model output for a visual comparison of model accuracy.
