Abstract
Turbulence data obtained over ocean waves during the BOMEX experiment of 1969 are presented. Procedures in measurement and analyses are described which include adjustments for possible platform, R/V FLIP, motion. Momentum transfer is shown to have been influenced by both stability and wind-wave coupling. The wind-wave coupling influence is separated from the stability influence and is described in terms of a linear dependence of the deviation from the logarithmic profile on C/u *, where C is the phase speed corresponding to the wave spectrum peak. As observed by others, a value of C/u * near 25 is associated with minimal wind-wave coupling influence. For C/u * greater than 25, momentum transfer is decreased relative to the neutral profile prediction. Expressions are also presented for the wind-wave coupling influence on relative intensities, Σ u /u *, Σ u /u * and δ w/u *. Values of the relative intensities approximate neutral overland values when the expressions are written such that the wave influence is zero near a C/u * value of 25.
