Wave forecast WAM

Model characteristics

The wave forecast of our group is based on the ECMWF version of WAM (CYCLE 4) model (WAMDI group, 1988, Komen et al., 1994). It is a third generation wave model, which computes spectra of random short-crested wind-generated waves, being one of the most popular and well tested wave models. It is the first model that solves the complete action density equation, including non-linear wave - wave interactions.

Here we present the basic characteristics of our version.
