| Outline of Final Research Achievements |
Comprehensive investigations such as numerical and wind-tunnel water tank experiments and field observation have been carried out to reveal the influence of the transition, breaking and turbulence processes at the surface of wind waves on the mechanism of gas exchange across the ocean surface. We examined characteristics of the drift current and the transition of wind-wave surface, and fluid dynamical parameters to express them. Useful findings have been obtained for quantifying the ocean boundary process and modeling of the gas transfer velocity. In addition, the gas transfer velocity at the ocean surface has been estimated on the basis of numerical results using a numerical wave model and wind information, and the simulation procedure for ocean-surface transport process has been provided.
