Abstract

Abstract

The frequency spectrum of wind-generated microscale waves is brought forward using the color image collected by a sea surface microstructure optical measuring device. And on this basis, the relationship between the wave number spectrum and frequency spectrum of the microscale waves can be established utilizing dispersion relations of capillary gravity waves. Furthermore, the response of the frequency spectrum of the microscale waves to the change of frequency is studied. It can be found that the frequency spectrum of the microscale waves is proportional to the power of α of frequency and that the value of α which is unique at the same speed increases with speed.
