| Zusammenfassung |
| The surface-drag and mass-transfer coefficients are determined within a
self-consistent problem of wave-induced perturbations and mean fields of
velocity and density in the air, using a quasi-linear model based on the
Reynolds equations with down-gradient turbulence closure. Investigation of a
harmonic wave propagating along the wind has disclosed that the surface drag
is generally larger for shorter waves. This effect is more pronounced in the
unstable and neutral stratification. The stable stratification suppresses
turbulence, which leads to weakening of the momentum and mass transfer. |
