We simulate the dynamic evolution of nonlinear water waves coupled with wind turbulence. We first investigate simple wave trains to obtain pressure distribution, based on which parameters for wave growth are quantified and their dependence on wave age and wave steepness is shown. We then investigate broadband waves to obtain physical insights to wind forcing for phase-resolved wavefield simulation. It is found that for long wave components, the wave growth parameter can be approximated by the value of the corresponding monochromatic waves; for short waves, stochastic modeling is suggested.
