Progress during the NOPP Wave Model Improvement Program
- View All
This paper reviews the research activities that were carried out under the auspices of the National Ocean Partnership Program (NOPP) to advance research in wind wave modeling and transfer maturing technologies into operational community models. Primary focus of research activities that were funded under this program was to improve the source terms associated with deep water wind waves with a secondary focus on shallow water processes. While the focus has been on developing capabilities for stochastic phase averaged models, some of the research work reported here also touches on phase resolved models as well as updates that are needed to the classical stochastic equations to be applicable in shallow water conditions. The primary focus is on the development of new source terms to account for wave generation, dissipation and nonlinear wave-wave interactions. A direct result of this program has been the development of new physics packages in operational wave models that have improved forecast skill from 30 to 50 percent. Since this is an overview paper summarizing all the activities that were undertaken under this program, only the major results are presented here. The readers are directed to other publications for more details. The paper ends with a discussion of the remaining major challenges in wind wave modeling, from the larger open ocean scales to the smaller coastal domains.
