Relationship between the observed and weakly-turbulent spectra of surface gravity waves

  • 14 Accesses

Abstract

The theory for weakly-turbulent surface gravity waves normally identifies some auxiliary function (weakly-turbulent spectrum) with the actual (observed) wave spectrum. In this paper, a general formula for the relationship between weakly-turbulent spectra and observed spectra is derived, and a numerical calculation is provided to show the difference between them. In particular, violation of the exponential nature and angular distribution of weakly-turbulent spectra is noted, along with the occurrence of secondary peaks. Quantitatively, the weakly-turbulent spectra differ insignificantly from the observed spectra.
