The Challenge

• Shelf waters deeper than 3 meters and shallower
  than about 30 meters have often been ignored in
  the past because of the very difficult operating
  conditions and the complex dynamics, where the
  water is filled with turbulent boundary layers.

Regional Ocean Modeling System (ROMS) Development
Initiated by Rutgers/UCLA
1997

• Features
• Free-surface, hydrostatic, primitive equation
  model
• State-of-the-art turbulence closure schemes for
  atmosphere and ocean
• Efficient coarse-grained, shared-memory, parallel
  code
• Enables support of high-resolution real-time
  coastal forecasting applications
