The evolution of a windsea spectrum is strongly controlled by the nonlinear energy transfer S n1 due to resonant wave—wave interactions. Since the exact computation of this process is very time-consuming, most operational wave models are dependent on some form of parametrization of this source function. However, recent, more efficient methods of computing the exact three-dimensional integral expression for S nl (Hasselmann and Hasselmann, 1981, 1985) have made it feasible to carry out integrations of the wave transport equation with the exact form for S nl, at least for simple cases in which only one integration variable occurs.
