The Wind-Induced Wave Growth Rate and the Spectrum of the Gravity-Capillary Waves

摘要: Abstract A form of the spectrum gravity-capillary waves is suggested, based on a balance wind input, spectral flux divergence, viscous dissipation, and modulation from wave-drift interaction. The in alongwind direction expressed as where k wavenumber, m α are constants, u* friction velocity, δ threshold c short-wave phase mo zeroth moment nondirectional frequency long-wave orbital velocity. For shorter capillary waves, addition dissipation due to eddy viscosity needed. kinematic wave breaking criterion applied calculation dissipation. It found that this interactions, has effect suppressing at higher speed yields good agreement with measurements both directional spreading rate. also fluctuation...
