Vertical profiles for mean wind, standard deviations of velocityfluctuations, and wave-induced part of the momentum flux over a wavy fluidsurface are calculated in the Cartesian coordinates on the basis of recentnumerical results by Chalikov and Rainchik. Besides, calculations of spectrafor surface elevation and wave-induced velocity components at this surface arecarried out. Unlike the profiles typical to the near-wall turbulence, thecalculated wind-velocity profiles deviate significantly from the logarithmiclaw throughout the entire trough-crest zone of wind waves, and the wave-inducedpart of the momentum flux changes its sign in close vicinity of the meansurface level. Vertical scales of the profiles features are estimated. Spectralanalysis of the water-surface oscillations and wind-velocity componentssuggests nonlinear and strongly anisotropic dynamics of the system underconsideration. Points of application of the results obtained are discussed.
