The mean speeds of short wavelength wind-generated waves (wavelengths less than 4 cm) have been obtained from Doppler spectra measured at very short fetch in a wave tank for wind speeds up to 15 m sec−1. These speeds are compared with phase speeds calculated from a first-order perturbation of the wind drift and reasonable agreement is obtained. The measurements show that the difference between mean wave speed and the mean surface drift becomes quite small for wind speeds exceeding 12 m sec−1.
