Abstract : Simultaneous measurements of mean wind speed, horizontal wind velocity, vertical wind velocity, and water height were made during the summer of 1968 at an exposed field site off the New England Coast. Measurements were conducted with and without an artificial sea slick on the water, demonstrating the importance of small waves to air-sea interaction. Analysis indicates better than 90 percent of the validly measured wind profiles are logarithmic. The friction velocity U* is a linear function of wind speed. The roughness length parameter is highly structured, and can be explained in part by the Kelvin-Helmholtz instability and the onset of wave generation. (Author)
