Modeling

Currently, four modeling systems produce a comprehensive ocean state prediction for the main Hawaiian Islands.

Circulation Modeling: Ocean circulation and current forecasts are made daily using the Regional Ocean Modeling System (ROMS) for the Main Hawaiian Islands with increased resolution on Oahu. Global coverage is provided by the Navy Coastal Ocean Model (NCOM).

Wave Modeling: Ocean waves are forecast daily using WaveWatch III and SWAN models with domains that extend throughout the entire Pacific with increasing resolution to each of the main Hawaiian Islands.

Tide Modeling: Tide forecasts are produced separately for the Big Island and the remaining main Hawaiian islands by Glenn Carter of the University of Hawaii.

Atmospheric Modeling: The Weather Research and Forecasting (WRF) model produces daily atmospheric forecasts covering all of the Hawaiian islands as well as detailed forecasts for each of the main Hawaiian Islands. Global coverage is provided by NOAA/NCEP's Global Forecasting System (GFS).
