JONSWAP'S PARAMETERS - SORTING OUT THE INCONSISTENCIES

The original prognostic equations for the JONSWAP-spectrum contained inconsistencies. A subsequent paper (Hasselmann et al 1976, J. Phys. Oceanogr. 6, 200-208) attempted to regularise the situation. this paper shows that there were still inconsistencies in the prognostic equations giving overestimations of the first moment of the spectrum and consequently the significant wave height. The prognostic equations are reworked systematically and results presented. It is shown that variables for the degree of peakedness and peak region widths must be used to achieve consistent results.
