| Research Abstract |
In order to understand the mechanism of gas-transfer at wind waves with whitecaps, a PTV measurement technique was developed to measure flow fields under wind wave. The measurement technique was applied to flow field under white-cap which occurred by wind wave braking. The properties of air flows over wind waves and bubbles which generated by wave breaking were also measured by image processing techniques. In addition, global CO_2 exchange between air-sea by breaking waves was estimated by the field measurement data and satellite data.
