EFFECTS OF PULSATING WIND ON VELOCITY PROFILES AND MICROSTRUCTURES

Friction velocities of pulsating winds were measured as well as slope and curvature distributions of the disturbed water surface. The results obtained with the same average wind speed, but with pulsations of various frequencies and amplitudes are compared. The pulsations are found to be critical on wind and wave structures when the regime of the wind boundary layer is affected. The influence of pulsations becomes secondary, when the wind boundary layer is aerodynamically rough. A distinct feature of this regime, generally occurring in the field, is that more capillaries are produced by pulsating winds. /Author/
