IFS Documentation Cycle CY28R1

Abstract

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 followed by a brief discussion of the ECMWF wave data assimilation scheme. The document closes with a presentation of the ECMWF version of the numerical scheme and of the structure of the software.
