Laboratory investigations of the structure of the turbulent boundary layer above the waves under conditions modeling near-water boundary layer of the atmosphere for strong and hurricane winds were carried on the Wind-wave channel of IAP RAS for 10-meters equivalent wind speed from 10 up to 48 m/s. Air flow velocity fields and mean wind velocity profiles over the curved wavy surface averaged over turbulent fluctuations were obtained by using Particle Image Velocimetry (PIV) technique.
