Microscopic Structure of Disturbed Water Surface under Fluctuating Winds.

Abstract

Slope and curvature distributions of the disturbed water surface under, and shear velocities of, fluctuating winds were measured. The results obtained with the same average wind velocity but with fluctuations of various frequencies and amplitudes are compared. The fluctuations are found to be critical on wing and wave structures, when the regime of the wind boundary layer is affected. The influence of fluctuations becomes secondary, when the wind boundary layer is aerodynamically rough. For the latter regime, generally occurring in the field, a distinct feature is observed with more capillaries produced by fluctuating winds. (Author)
