What the Prediction System Provides

• High spatial resolution, down to ~1 km horizontally with 28 levels in the vertical for waves, currents, temperature, and salinity.

– This means providing conditions and predictions where they are needed around the coastal regions of Hawaii.

• Time histories of wave spectra, three-dimensional currents, temperature T, and salinity S (thus, four-dimensional sound speed structure).

– Sound speed can be used for Anti-Submarine Warfare purposes.

• Ingestion of atmospheric forcing for momentum, mass, and heat fluxes at the air-sea interface, inverted barometer effect.

– Predict daily heating, cooling of water.

– Predict tropical storm current fields, storm surge, and the inverted barometer effect.

• Sea level and three-dimensional tidal prediction.

– Tidal surface height variations as well as tidal currents.

– Can predict internal tides.

• Ingestion of satellite sea surface temperatures and subsurface T-S fields from the US Navy’s NCOM Pacific Ocean circulation model.

• Ability to include wave-related flow fields and effects.

• Ability to assimilate two-dimensional patterns of surface current observations.

• Can assimilate CODAR data.

• Ability to simulate within the water column the concentration of a conservative tracer.

• Can have offshore or onshore discharges or intakes of rivers or outfalls (e.g., sewage).
