The NOAA WAVEWATCH IIIβ„Ά operational wave model suite consists of a set of
five wave models, based on version 2.22 of WAVEWATCH IIIβ„Ά. All models use
the default settings of WAVEWATCH IIIβ„Ά unless specified differently.
- The global NWW3 model
- The regional Alaskan Waters (AKW) model
- The regional Western North Atlantic (WNA) model
- The regional North Atlantic Hurricane (NAH) model
- The regional Eastern North Pacific (ENP) model
- The regional North Pacific Hurricane (NPH) model
All regional models obtain hourly boundary data from the global model. All
models are run on the 00z, 06z, 12z and 18z model cycles, and start with a
6h hindcast to assure continuity of swell. All models provides 126 hour
forecasts, with the exception of the NAH model (72 hour forecast). No wave
data assimilation is performed. All models are based on shallow water
physics without mean currents. Additional model information is provided in
the table and bullets below. The four time steps are the global step,
propagation step for longest wave, refraction step and minimum source term
step.
