Wave models are an important component of the National Weather Service suite of products, and support both the Ocean Prediction Center and WFOs with marine forecast responsibilities. These dynamical wave models are driven by NWP forecast 10-m winds; the GFS for the global and basin-wide wave models, and the NAM-B CONUS nest for the Great Lakes wave model.


The Wave encyclopedia describes the WaveWatch III model used by the NWS, the US Navy Fleet Numerical Meteorology and Oceanography Center (FNMOC) wave model, and the Great Lakes Wave model. We describe wave model structure, wave generation methods, and wave propagation and dispersion methods, plus the post-processed output from these models.
