“…5.2). In principle, such interactions can be included in the WAVEMATCH III model (e.g., Tolman 1991;Holthuijsen and Tolman 1991). This will, however, require an accurate model to describe nearsurface mean currents that are due to tides, storm surges, and deep ocean circulation such as the Gulf Stream for the entire wave model domain.…”

The accuracy of the operational wave models at the National Centers for Environmental Prediction (NCEP) for sea states generated by Hurricane Isabel is assessed. The western North Atlantic (WNA) and the North Atlantic hurricane (NAH) wave models are validated using analyzed wind fields, and wave observations from the Jason-1 altimeter and from 15 moored buoys. Both models provided excellent guidance for Isabel in the days preceding landfall of the hurricane along the east coast of the United States. However, the NAH model outperforms the WNA model in the initial stages of Isabel, when she was a category 5 hurricane. The NAH model was also more accurate in providing guidance for the swell systems arriving at the U.S. coast well before landfall of Isabel. Although major model deficiencies can be attributed to shortcomings in the driving wind fields, several areas of potential wave model improvement have been identified.

Standard Form 298 (Rev. 8-98)Prescribed by ANSI Std. Z39.18Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. This report consists of supplementary materials for an article, accepted for publication in the Journal of Atmospheric and Oceanic Technology, dealing with directional wave model validation by the same authors. These materials provide important background information for this companion paper, but were not included due to journal page limitations. Part I of this report provides a review of literature related to directional validation of wave models. Part II of this report discusses a number of issues that were raised by reviewers to the paper with particular focus on extensive non-directional validation of wave models. Also presented are validation of higher order moments, a summary of alternate methods of validation of directional spreading, a discussion of data-adaptive methods, and discussion of sensitivity of results to the handling of the high frequency range of the wave spectrum.

“…Problems with grid methods are that high spatial resolution is required for an accurate description of bathymetric and topographic effects, and high spectral resolution is required for accurate swell propagation over large distances. It should be noted that where the same governing equation is solved, the different numerical methods should ideally produce the same result, as demonstrated in Holthuijsen and Tolman (1991), for example.…”

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
