Abstract
The wave-induced fluctuations of wind velocity over wind-waves measured in the wind tunnel experiment (Ichikawa andImasato, 1976) are compared with the numerical results estimated by a linear model (Model II) on the turbulent wind field over a dominant component of wind-waves. In the Model II, the undulation of mean air flow is introduced by adopting the curvilinear co-ordinates, and the existence of viscous sublayer and the influence of underlying wind-waves to background atmospheric turbulence are taken into account. The numerical results estimated by the Model II are in good agreement with the experimental results. The good agreement, which was not obtained from the previous model (Model I) in the Cartesian co-ordinates, is shown to be attributed to the undulating mean flow introduced in the Model II.
