A RE-ANALYSIS OF THE SPECTRA OBSERVED IN JONSWAP

[摘要] The frequency spectra of wind-driven waves observed during JONSWAP are re-analyzed to establish whether the Toba formulation for the highfrequency tail (~f ) fits the data better than the Phillips formulation (~f_ ) used originally in the JONSWAP project. The results indicate that the f-,*-tail provides a better fit to the observed spectra. The proportionality factor in Toba's spectrum, which is theoretically expected to be a universal constant, is found to be uncorrelated with the growth stage of the waves.
