The operational ocean wave predictions of NOAA/NWS/NCEP use the wave model WAVEWATCH III^® using operational NCEP products as input.

Detailed description of the WAVEWATCH III^® model
and source code distribution.

The model is run four times a day: 00Z, 06Z, 12Z, and 18Z. Each run starts with 9-, 6- and 3-hour hindcasts and produces forecasts of every 3 hours from the initial time out to 180 hours (84 hours for the Great Lakes).

The wave model suite consists of global and regional nested grids. As background information, a list of selected references and a chronological list of model changes are available. Finally, validation data are available for the multi-scale model.

NOAA WAVEWATCH III^® CFSRR Reanalysis Hindcasts

To generate a wave climatology, a simulation of the 30-year period of 1979-2009 has been run with the NOAA WAVEWATCH III^® using the Tolman-Chalikov physics package with 16 regular lat-lon grids and the new NCEP Climate Forecast System Reanalysis and Reforecast (CFSRR) homogeneous data set of hourly 1/2° spatial resolution winds.
