Ocean waves can affect the roughness of the ocean surface, and the waves generated by tropical cyclones impact the momentum and energy fluxes across the air-sea interface. In this study, the impacts of ocean waves on the momentum and energy fluxes under tropical cyclones is examined by using the tropical cyclone observation dataset IBTrACS (International Best Track Archive for Climate Stewardship) and the simulations from wave model WW III (WAVEWATCH III). It is found that the intensity of tropical cyclones increased by about 1 m/s every decade in the past 30 years, but the change of translation speed is not obvious. For the stronger tropical cyclones, the difference for momentum flux and the energy flux between the air-sea interface can be significantly increased by the waves. Owing to the asymmetry of wind and surface wave fields under tropical cyclones, momentum difference and energy difference also demonstrate asymmetric distribution: the area with larger momentum difference is behind the moving direction of tropical cyclone, while energy difference is the largest in the right-rear quadrant, and both are relatively smaller in the left front quadrant. The inverse wave age is highly correlated with momentum difference and energy difference, and the correlation coefficient is about 0.95, indicating that the younger the surface wave, the more momentum and energy absorbed and stored by surface wave field. The inverse wave age increases with the increase of tropical cyclone translation speed, and the speed is positively correlated with momentum difference and energy difference according to the correlation coefficient above 0.8. Therefore, the surface waves affect the distribution and magnitude of momentum and energy input from the atmosphere to the ocean under tropical cyclones. In the future study of ocean boundary dynamics and thermodynamics, especially the study of tropical cyclones, considering the influence of ocean wave evolution is necessary.
