“…the wave height-towater depth ratio for breaking waves, is set to 0.73. Wind-wave growth is generated using the Komen formulation (Komen et al 1984). A backward-in-space, backward-in-time advection scheme is used for iteration.…”

An integrated nowcast/forecast modelling system covering the South Atlantic Bight and Gulf of Mexico (SABGOM) is in operation, utilizing sophisticated model coupling and parallel computing techniques. This three-dimensional, highresolution, regional nowcast/forecast system provides a nowcast and an 84 h forecast of marine weather, ocean waves and circulation, and basic marine ecosystem conditions to the public via a Google Map interface. The SABGOM system runs automatically daily and supports a series of user-defined online applications. Extensive model validations were performed online against in situ and satellite-observed ocean conditions. The SABGOM system exhibits a reliable capability of providing valuable forecasts.

“…Sometimes, such attempts have been based on trying to fit the dissipation term to an existing analytical model (Komen et al, 1984;Polnikov, 1993), but mostly such terms are tuning knobs that may or may not involve reference to the physics.…”

“…Nevertheless many recent experimentally-discovered features of the breaking-induced dissipation have not yet been incorporated in wave models (see subsection 4.1 above). Particular physical mechanisms that have been identified by modellers for inclusion are breaking threshold behaviour based on local spectral saturation (e.g., Alves and Banner, 2003) rather than integral wave steepness (Komen et al, 1984), and additional short wave extinction through cumulative nonlinear interaction with longer waves (e.g., Donelan, presentation at WISE-12, Miami, USA, 2005), amongst several others.…”

“…Instead, we shall analyse the progress of methodology for modelling and verification of the dissipation functions and indicate possible future ways for this to progress. In brief, the major historical stages of the methodology of tuning the dissipation term can be summarised as follows: 1) considering the balance of source terms in order to obtain the known integral evolution curves (e.g., Komen et al, 1984); 2) validating the spectral balance evolution to ensure the known spectrum development behaviour is satisfied (e.g., Banner and Young, 1994); 3) uncoupling the dissipation term from the source term balance in an attempt to tune it directly against known wave breaking characteristics (e.g. Banner, Kriezi and Morison, presentation at WISE-11, Reading, England, 2004); 4) further tuning the stand-alone dissipation function against other dissipation-related properties and constraints (next step); 5) employing exact physics, both experimental and theoretical (future).…”

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

“…WAMDI Group, 1988) integrates the basic transport equation describing the evolution of a two-dimensional ocean wave spectrum without additional ad hoc assumptions regarding the spectral shape. The windinput source function is adopted from Snyder et al (1981), while the dissipation source function is based on the formula proposed by Komen et al (1984). Both functions are calculated through Eqs.…”

Wind-wave modelling aspects within complicate topography

Abstract. Wave forecasting aspects for basins with complicate geomorphology, such as the Aegean Sea, are investigated through an intercomparison study. The efficiency of the available wind models (ECMWF, UKMO) to reproduce wind patterns over special basins, as well as three wave models incorporating different physics and characteristics (WAM, AUT, WACCAS), are tested for selected storm cases representing the typical wind situations over the basin. From the wave results, discussed in terms of time-series and statistical parameters, the crucial role is pointed out of the wind resolution and the reliability of the different wave models to estimate the wave climate in such a basin. The necessary grid resolution is also tested, while for a specific test case (December 1991) ERS-1 satellite data are compared with those of the model.
