IFS DOCUMENTATION Part VII ECMWF WAVE MODEL ( CY 25 R 1 ) ( Operational implementation 9 April 2002 )

This document is partly based on Chapter III of "Dynamics and Modelling of Ocean Waves" by Komen et al, 1994. For more background information on the fundamentals of wave prediction models this book comes highly recommended. Here, after a historical introduction, we will describe the basic evolution equation, including a discussion of the parametrization of the source functions. This is then fol...
