Existing empirical relations for the gas transfer velocity at wind-wave interface are expressed in terms of wind speed only, and so the difference in their estimated values may be caused by wave parameters such as the wave age. A new model of the transfer velocity describing the effects of wave breaking is formulated on the basis of hybrid models of Woolf (2005) and Soloviev et al.(2007). The model expression and the values of parameters are examined in comparison with existing empirical relations. The present model can estimate wave-dependent gas transfer velocities and shows that variations of wind-speed dependence in empirical relations may be based on the wave age. Also, the present model may describe the behaviors of laboratory data with the wave age.
