Forecasting and Hindcasting Waves In and Near the Marginal Ice Zone: Wave Modeling and the ONR Sea State Field Experiment
Abstract
This report describes the development, application, and evaluation of wave models for the ONR Sea State Departmental Research Initiative. The Sea State field experiment is described, with particular attention to wave measurements and the wave conditions during the field experiment. Wave forecasting in support of the cruise is described. Implementation of the effects of sea ice on waves in the numerical wave model WAVEWATCH III(registered) is described. The role of the ice forcing in the wave model performance is evaluated by contrasting different ice products and applying them in hindcasts. The relative strengths and weaknesses of the products are discussed. The relative skill of hindcasts with different physical parameterizations is also quantified for the various wave experiments conducted during the cruise. A model-data inversion is conducted to estimate the frequency distribution of the dissipation of wave energy by ice, separated by buoy type and wave experiment. A subset of the inversion results is used to create a new empirical physical parameterization, and this parameterization is compared with distributions given in the literature, and other model parameterizations.
