1. Key points:
• Assess the impact of wave
effects on currents and
hydrography in the upper
ocean.
• New wave model physics in
operational wave models.
• Assess the impact of wave-
mean flow on coupled
forecast systems.

5. WaveFlow - summary of results
5
● The WaveFlow project has delivered a major upgrade of the open source version of WAM, v4.7.
This version includes the physics package from Ardhuin et al (2010) as implemented in EC-WAM, the
wave model component of the Integrated Forecast System of ECMWF.
● The forcing is provided by ERA5 and a set of hindcast integrations where EC-WAM is run with ERA5
wind forcing with and without the new physics. These forcing data sets are now available to the
community.
● Comparison against buoy spectra in the North Sea indicate that the new wave model physics generally
improves the spectral representation
● The updated NEMO4 with Stokes drift advection included has been tested in WaveFlow (Wu et al,
2019a). This new NEMO model code is also available to CMEMS MFCs.
● The new wave model physics has overall a rather small impact on the coupled ECMWF system.
● The OSMOSIS scheme has been tested and found to give generally good results, but not in very
shallow areas.
● The new WAM physics is already being used for the wave hindcast under production by the ARC-
MFC.
