【 摘 要 】

Similarity relationship among non-dimensional significant wave parameters are discussed which is based upon the 3/2 power law. The characteristics of the wind wave spectra in deep water are investigated by using the parameters of JONSWAP spectrum and the 3/2 power law. From theoretical and empirical arguments, it is confirmed that a f" power law exists at high frequency range, that JONSWAP spectrum parameter y and a are varied with fetch, and that parameter a and y satisfied a -1/3 power law. In shallow water region, spectral form of wind waves is varied with the shoaling coefficient. Through the analysis of the wind wave spectra, a new spectral formula is obtained.
