NOTICE: Discontinuation of Hurricane Wave (multi_2) Model

Effective on or about July 11, 2017, beginning with the 1200 Coordinated Universal Time (UTC) run, the National Centers for Environmental Prediction (NCEP) [has discontinued] the Hurricane Wave (Multi_2) Model and all output. This includes NOAAPORT and NCEP Web services.

NCEP solicited comments on the proposed discontinuation of the Hurricane Wave modeling system under PNS 17-06. The proposal was to replace these products with higher-quality data generated by the next coupled Hurricane Weather Research and Forecasting (HWRF) system. NCEP received no negative feedback so we will proceed with this change.

Service Change Notice 17-71

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 multigrid model.

NOAA WAVEWATCH III® Hindcast and Reanalysis Archives

MMAB currently maintains two classes of WAVEWATCH III® hindcasts.

Detailed descriptions of the hindcasts and reanalyses, with links to the datasets, validation statistics from buoy match-ups, and visualizations of the model data fields, can be found in the WAVEWATCH III® Hindcast and Reanalysis Archives

WAVEWATCH III® Tutorials

Two COMET modules are available regarding WAVEWATCH III® and analysis of ocean swell:

Registration is free for the courses.
