Title: A NEW WIND WAVE SPECTRUM AND ITS APPLICATIONS
Abstract: In this paper a new wind wave spectrum is proposed. During the course of the wave formation, the wind speed and duration together with the fetch appear in the spectrum as parameters, and if either the duration or the fetch has attained the magnitudes required for the fully developed waves, the spectrum exhibits features similar to those of the growing wind wave spectra of Prof.Wen's. As the waves become fully developed, only the wind speed is left in the spectrum as a parameter, the spectrum being thereby reduced to a form similar to that of Roll-Fischer's. The proposed spectrum not only simplifies wind wave analyses, but also permits such important characteristics of the wind waves as height, period, and fetch necessary for the full development of waves to be expressed in analytic forms instead of diagrams and charts. The results based on the proposed spectrum have been compared with observations; so far as the cases examined are concerned, the results here obtained show better agreements than those given by the currently employed theories within the wind speed range of 6-20 metres per second.
