In this study, surfaces waves characteristics of fully-developed wind-driven turbulent flow, the maximum wind speed 2m/s, were investigated used DNS data by means of MARS method for a coupled gas-liquid turbulent flow. As the results, large horizontal "scales" shaped wind driven water surfaces consists of the low wave-number surface fluctuations, of which the spectra follow the -4th power law. High wave number surface fluctuations were inactive in surface fluctuations or fluid velocity turbulent intensity behaviors near air-liquid interface. Dynamic processes compared with the coherent turbulent flow structures over fixed wavy wall, were observed, and were caused from the control factors with the phase difference, wind, surface waves and water velocity, in the air-liquid interface interation.
