Announcement: Waves Summer School
The Waves Group at NCEP/NOAA in partnership with the
University System of Maryland Foundation will be offering a one-week Waves Workshop at
the University of Maryland (UMD) College Park Campus, July 13-17,
2015. Topics covered will include wave dynamics and modeling, basics
of the WAVEWATCH III® model, grids, structures, numerics,
oceanic and nearshore applications. The workshop will consist of
morning lectures and afternoon tutorials.
The 20 available
spots have been filled, and registration is now closed.
As of 21 January 2015 we are changing the output directory formats on
our production FTP server
to separate the products by their corresponding modelling system.
The combined output directory name wave.YYYYMMDD
will be replaced by
where [modelID] is:
|multi_1||Global wave model mosiac driven by GFS winds
|multi_2||Global hurricane wave model mosiac driven by a blend of GFS
and HWRF winds
||glw||Great Lakes modeling system
|gwes||Global wave ensemble system
||nfcens||A combined wave ensemble product from NCEP and
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
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
