In 1970, Yefimov proposed a linearized model for predicting the effect of water waves on the adjacent wind flow. The authors investigate the impact of the non-linear terms neglected in his model. In this investigation, the sea surface is described by a single harmonic in x and the wave induced motion in the atmosphere is restricted to this harmonic. Buoyancy effects are neglected and the turbulent fluxes of momentum are approximated in terms of an eddy viscosity. The equations are integrated numerically until a steady-state is achieved. These solutions show that the nonlinear terms which were neglected by Yefimov are important, and that they generally lead a smaller response. The numerical solutions for the mean wind are compared with observations obtained by Davidson and Brutsaert. Although the numerical solutions show some local agreement with the observations, the general behavior is at variance with the observations
