“…The atmospheric component is based on the Workstation Eta non-hydrostatic limited area model (Papadopoulos et al, 2002;Janjic, 2001;Nickovic et al, 2001;Mesinger et al, 1988). The ocean wave component is based on the fourth generation OpenMP (OMP) version of the WAM model (Monbaliu et al, 2000;Korres et al, 2011) and the resulting name of the coupled system is WEW.…”

“…In order to reduce unrealistic energy loss at boundary points in cases where the waves propagate parallel and near the coast, the technique of Monbaliu et al (2000) was applied wherein an alternative octant propagation coordinate system was introduced in the original WAM model code. For the octant advection scheme, eight propagation directions are defined instead of four in the classical quadrant scheme.…”

A fully coupled atmosphere–ocean wave modeling system for the Mediterranean Sea: interactions and sensitivity to the resolved scales and mechanisms

Abstract. It is commonly accepted that there is a need for a better understanding of the factors that contribute to air-sea interactions and their feedbacks. In this context it is important to develop advanced numerical prediction systems that treat the atmosphere and the ocean as a unified system. The realistic description and understanding of the exchange processes near the ocean surface requires knowledge of the sea state and its evolution. This can be achieved by considering the sea surface and the atmosphere as a continuously crosstalking dynamic system. Following and adapting concepts already developed and implemented in large-scale numerical weather models and in hurricane simulations, this study aims to present the effort towards developing a new, highresolution, two-way fully coupled atmosphere-ocean wave model in order to support both operational and research activities. A specific issue that is emphasized is the determination and parameterization of the air-sea momentum fluxes in conditions of extremely high and time-varying winds. Software considerations, data exchange as well as computational and scientific performance of the coupled system, the so-called WEW (worketa-wam), are also discussed. In a case study of a high-impact weather and sea-state event, the wind-wave parameterization scheme reduces the resulted wind speed and the significant wave height as a response to the increased aerodynamic drag over rough sea surfaces. Overall, WEW offers a more realistic representation of the momentum exchanges in the ocean wind-wave system and includes the effects of the resolved wave spectrum on the drag coefficient and its feedback on the momentum flux.

This paper is the product of the wave modelling community and it tries to make a picture of the present situation in this branch of science, exploring the previous and the most recent results and looking ahead towards the solution of the problems we presently face. Both theory and applications are considered.The many faces of the subject imply separate discussions. This is reflected into the single sections, seven of them, each dealing with a specific topic, the whole providing a broad and solid overview of the present state of the art. After an introduction framing the problem and the approach we followed, we deal in sequence with the following subjects: (Section) 2, generation by wind; 3, non-linear interactions in deep water; 4, white-capping dissipation; 5, non-linear interactions in shallow water; 6, dissipation at the sea bottom; 7, wave propagation; 8, numerics. The two final sections, 9 and 10, summarize the present situation from a general point of view and try to look at the future developments. Keywords

“…The ProWAM model, a revised version of WAM model, solves a wave action balance equation without any predefined shape of the energy spectrum and predicts the wind and swell wave fields from surface forcing and other oceanic processes (see Günther et al, 1992;Monbaliu et al, 2000). The POLCOMS model was developed at Proudman Oceanographic Laboratory (presently National Oceanography Centre, Liverpool).…”

This paper presents an integrated 'Clouds-to-Coast' ensemble modelling framework of coastal flood risk due to wave overtopping. The modelling framework consists of four key components: meteorological forecasts, wave-tide-surge predictions, nearshore wave models and surf zone models. This type of ensemble prediction approach allows us to estimate the probabilities of various outcomes and so improve our understanding of the reliability of results. It also provides a measure of the uncertainty associated with predictions, which can be particularly large for extreme storms, and allows us to assess how the uncertainty propagates from meteorological forecasts to overtopping and subsequent coastal flood risk predictions.
