Model v 4.18 is the new public release of WAVEWATCH III. There have been significant upgrades to the modeling system since the last public release (v 3.14). WAVEWATCH III has now transitioned from an NCEP model to a community driven effort with developers spanning several organizations.
The NOMADS (NOAA Operational Model Archive Distribution System) data server offers WAVEWATCH III data access. The server can be accessed at nomad5.ncep.noaa.gov/ncep_data/index.html, and offers interactive graphics, direct data downloads, and DODS/OpenDAP access.
EMC Operational Wave Models. Here you can find links to model forecast data as well as images generated from the EMC suite of operational wave models. These models are based on the 3 rd generation wave model WAVEWATCH III ® using operational NCEP products as input.
WAVEWATCH III™ solves the random phase spectral action density balance equation for wavenumber-direction spectra. The implicit assumption of this equation is that properties of medium (water depth and current) as well as the wave field itself vary on time and space scales that are much larger than the variation scales of a single wave.
WAVEWATCH IIITM version 3.14 3 model grid (new output type), and provides partitioned wind sea and swell output elds (publication in preparation). With the introduction of the multi-grid model driver, active bound-ary points can now be placed at the outer points of the grid. Also,
WAVEWATCH III, however, differs from its predecessors in many important points such as the governing equations, the model structure, the numerical methods and the physical parameterizations. WAVEWATCH III solves the spectral action density balance equation for wavenumber-direction spectra.
WAVEWATCH III that can be obtained by following Chapters 2 through 5. This is the user manual and system documentation of version 5.16 of the third-generation wind-wave modeling framework WAVEWATCH III
• Adding SMC grid and rotated grid options (sections 3.3.5 and 3.3.9, model version 4.13). • BYDRZ source term package (section 2.3.10, model version 4.14).
Third generation wave model of WAM descent, but with many differences : Governing equations (action versus energy). Grid system (wavenumber on variable grid versus relative frequency). Numerics (dynamic time stepping, higher order propagation schemes, GSE alleviation techniques).
The Global Ensemble Forecast System - Wave (GEFS-Wave) is a one-way coupling of the GEFS atmospheric model with the WAVEWATCH III wave model. This allows for an increase in frequency of the wind forcing from 3 hours to 1 hour.
