The new version of the WAM code is Cycle 4.7 (before it was Cycle 4.5) has been implemented since 12Z run on
The main differences with respect to the previous version are updated physics, propagation of waves under sea ice, and a correction for the unrealistic growth of the waves in very high winds. Other differences are: a reformulation of the mean wavenumber and mean frequency as well as a new formulation for detecting freak waves. Also, wave refraction by bottom topography is included which was absent in the previous set-up.
