Model Upgrades

Global and Hurricane wave models upgraded

The Global and Hurricane wave models have been upgraded. More information is available in the Technical Implementation Notice (TIN)

Great Lakes model upgrade

Next week the Great Lakes model will be upgraded. More information on the upgrade can be found in the Technical Implementation Notice (TIN)

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.
