IMPORTANT NOTICE REGARDING THE WAVEWATCH III® MULTI-1 WEBSITE
The EMC WAVEWATCH III ® global wave model Multi-1 was
decommissioned in NCEP operations on March 22, 2021. It has been
replaced by a new configuration of the WAVEWATCH III global wave
model, called GFS-Wave, and coupled to the
Global Forecast System (GFSv16), as part of the
Unified Forecast System.
THIS WEBSITE IS NOT DISPLAYING MULTI-1 OR GFS-WAVE GRAPHICS
It is being maintained for archival and verification purposes only.
Here are the details (PDF) on how this will affect users of this site.
Output of the new GFS-Wave model is available on NOMADS and Production FTP
*under gfs.YYYYMMDD/CC/wave/gridded and gfs.YYYYMMDD/CC/wave/station
Graphics of the GFS-Wave model output will become available some time in April on the
Model Analysis and Guidance (MAG) site. Note
that the current WW3 link on that page is to a preliminary set of GFS-Wave
graphics. New graphics with more options will be added with the coming
update in May, and will be under GFS-Wave instead of WW3.
NOTICE:
The Global Wave Ensemble System (GWES) was discontinued on 23
Sep 2020 and has been replaced by an improved GEFS-Waves,
consisting of a one-way nesting of the WAVEWATCH III system with
the recently upgraded GFS Ensemble Forecast System. The NOAA
press release on the upgrade is
here, and information on GEFS is available
here.
The GEFSv12 Service Change Notice (issued 8/20/2020, PDF) is
here, and you can find information on the evaluation of the GEFS-Waves portion
of the GEFS system in the
Model Evaluation Group (MEG) Summary page on the
GEFSv12 upgrade
here.
The model data is available four times a day (0, 6, 12, 18)Z from:
-
Production FTP (gefs.YYYYMMDD -->cycle-->waves)
-
NOMADS (Ocean Models-->GFS Ensemble Wave-->(grib filter or https file download).
Details on the products can be found
here (scroll down to GEFS - Wave - Global).
Here you can view any of the individual WAVEWATCH III® graphic products
generated during the last six model runs. Simply follow the steps and
click to choose the Model, Forecast Zone, Model Run Time, Product, and then click
on a Forecast Time (0 is the nowcast, negative times are hindcasts, positive
times are forecasts). Buoy information for the selected region is also given
in the form of spectral plots, source term plots, and Spectral Bulletins.
Current Product Selection:
Australia-Indonesia (Global) (30 Hours Back) 2021/02/26 12z
Significant Wave Height and Peak Direction
The significant wave height is a
measure for the wave height, and closely corresponds to
what a trained observer would consider to be the mean wave height. Note that
the highest wave height of an individual wave will be significantly larger.
