Abstract: WAVEWATCH III (Tolman 1997, 1999a) is a third generation wave model
developed at NOAA/NCEP in the spirit of the WAM model (WAMDIG 1988,
Komen et al. 1994). It is a further development of the model WAVEWATCH
I, as developed at Delft University of Technology (Tolman 1989, 1991)
and WAVEWATCH II, developed at NASA, Goddard Space Flight Center
(e.g., Tolman 1992). It ... nevertheless differs from its predecessors on
all important points; the governing equations, the models structure,
numerical methods and physical parameterizations.
WAVEWATCH III solves the spectral action density balance equation for
wavenumber-direction spectra. The implicit assumption of these
equations is that the medium (depth and current) as well as the wave
field vary on time and space scales that are much larger than the
corresponding scales of a single wave. Furthermore, the physics
included in the model do not cover conditions where the waves are
severely depth-limited. This implies that the model can generally by
applied on spatial scales (grid increments) larger than 1 to 10 km,
and outside the surf zone.
Global and Regional Areas are available.
