Spectral analyses are performed on turbulence data obtained
over natural ocean waves during BOMEX. Results are
obtained for variance and co-variance spectra, phase and
coherence relationships, and amplitude ratios. Peaks
in the horizontal and vertical velocity spectra are observed
to correspond to the frequency of the wave spectra peaks.
Phase relationships tend to obey predictions of potential
flow theory in regions of the wave spectra peaks. However,
the wave related motion contributes to the momentum transfer
which is not predicted by potential flow theory. The ratio
of the wave induced disturbance to the sea surface displacement
is used to locate the wave spectra frequency for which
the level of measurement is a critical level. Results of the study are readily compared to existing wind-wave
coupling theories, both linear and non-linear.Approved for public release; distribution is unlimited.Lieutenant Commander, United States Navyhttp://archive.org/details/spectrofturbulen109451636
