Air-flow field over actual wind waves close to water surface was successfully measured using the PIV technique under a strong wind condition where the mean wind speed exceeds 10 m/s. It was found that the air-flow separation and the large-scale vortex are generated in front of breaking wind waves. A magnitude of the large-scale vortex corresponds to the amplitude of the breaking wind wave. The air-flow separation with inverse flow is generated for incipient wave breaking. Airflow separation with inverse flow was obtained in only 6% of all the studied cases, and progressive breaking wind waves without separation was obtained in about 60% of the cases.
