Abstract

Capillary waves caused by the wind were measured in a wave tank. The capillary waves' height, slope, and frequency composition were all measured. The wave heights (from trough to crest) were found to be between 0.06 and 8.8 mm for winds between 2.2 and 7.6 m/sec. Wind speed affects the distribution of frequencies (wavelengths), with more high frequency waves occurring at faster wind speeds. An S-shaped curve with the sharply rising part beginning at 3 m/sec may be seen when the rms value of the wave slope is plotted against the wind speed. The rms wave slope reached its greatest value in these studies at 17.5° and 7.6 m/sec.
