The air-sea interaction between the atmosphere and the ocean plays a vital role in the atmosphere and the ocean . Surface waves, present at the air-sea interface, can affect the turbulence of the bottom atmosphere and upper-ocean. Accordingly, they alter the wind stress, as well as the mixing. In most atmospheric numerical models, the influence of surface waves are not included. In this study, we incorporate the influences of surface waves (on wind stress and atmospheric mixing) on the atmosphere into atmosphere-wave coupled models. Simulation results show that including the surface waves affect the surface wind speeds (in particularly at high winds) as well as precipitation. Previous studies usually tune the parameterisations to measurements. However, our study show that the tuned parameters are not enough to catch the wave influences, and that a dynamic response is needed. So, we suggest that the surface wave influences should be included in climate as well as weather forecast models in further model development.
