Correlation of Micro- and Macroscopic Structures of Wind Waves and Differential Roughening and Smoothing of Surface Waves by Wind

Abstract

Simultaneous measurements were conducted in a wind-wave tank of the ripple slopes with an optical instrument and of the carrier-wave profiles with a wave-height gage. The experiments were conducted under various wind CONDITIONS: either steady or unsteady wind blowing over pre-existing regular surface waves. The data were analyzed to determine the slope distributions of ripples located on various portions of the carrier-wave profiles under steady wind, and the differential roughening and smoothing of the carrier waves under unsteady wind. The influences of pre-existing waves on the structure of the wind boundary layer, and on the slope statistics of ripples were also studied.
