Abstract
A theoretical description is given of the behavior of a broadband, small‐amplitude wind wave field in a perturbing internal wave velocity pattern. The theory includes the effect of the local wind. Specific predictions are made for the case of weak internal wave currents, and these predictions are compared with measurements. The theory predicts the magnitude of the mean square slope changes reasonably well, and it predicts the quadrant of the phases correctly. General features of the perturbed surface wave energy spectrum integrated in angle are also predicted reasonably well, and comparisons are made of the theoretical and measured local integrated spectrum at roughened areas and at slick areas.Keywords
