On the wind profile near a wavy surface

The formation of the mean-wind profile near the rough surface of a fluid is discussed. Classical definitions of the profile’s characteristics are presented, the treatments of the parameters of a logarithmic profile are considered, and the meaning of major concept is refined. On the basis of the numerical model developed by Makin and Kudryavtsev for the dynamic boundary layer, the mean-wind profile is calculated for different stages of wind-wave evolution. Differences between the calculated profiles and the classical logarithmic profile are discussed. A treatment is given for the established differences.
