Validation Study of Wave Breaking Influence in a Coupled Wave Model for Hurricane Wind Conditions
Abstract
As marine winds strengthen, wave breaking becomes increasingly widespread with potentially important consequences for offshore operations. Wave breaking is not included in present marine forecasts. This project addressed the incorporation of wave breaking physics into coupled sea state marine weather forecasting models, with aim of adding accurate wave breaking forecasts to the standard sea state variables. Our approach combined observational and modeling efforts. New results from our field data analyses were synthesized into accurate parameterizations for wave breaking occurrence and strength. The wind input source term was modified for compatibility with the other source terms and physical constraints. These refinements were incorporated in the dissipation and wind input source terms in the spectral wave evolution models used to generate forecasts. The model output results were evaluated critically in systematic tests from moderate to severe wind speeds. After extensive iterations, the model framework is ready for implementation and further testing in operational prototype models.
