A procedure for predicting the significant height and period of wind waves generated in a uniform fetch in deep water is presented in the closed-form expressions based on Wilson’s formulas, together with relevant design diagrams. Although Wilson’s formulas are relatively unknown in the United States, they are quite reliable. The relationship between the nondimensional minimum duration and the nondimensional fetch length is empirically expressed in a power law, which enables the analyst to judge whether the wave growth is limited by the wind duration or the fetch length. The correlation between the significant wave height and period also indicates the period approximately proportional to the 2/3 power of the wave height.read more

Weakly turbulent laws of wind-wave growth
TL;DR: In this paper, an asymptotic weakly turbulent relation for the total energy ϵ and a characteristic wave frequency ω* was derived and the self-similarity parameter αss was found in the numerical duration-limited experiments and was shown to naturally vary in a relatively narrow range, being dependent on the energy growth rate only.

Growth of wind waves with fetch observed by the Geosat altimeter in the Japan Sea under winter monsoon
TL;DR: In this paper, the wind speeds and significant wave heights derived from the Geosat altimeter were validated by comparing with the data obtained at Japanese ocean data buoy stations, and an experimental equation was derived in order to correct this error for the present study.
