Guedes Soares, C. (1984), “Representation of Double-Peaked Sea Wave Spectra”, Ocean Engineering, Vol. 11, Issue 2, pp. 185-207

About 1000 measured wave spectra from the North Atlantic and 6000 from the North Sea, were analysed so as to determine the frequency of occurrence of double-peaked spectra in sea states of different intensity. This type of spectrum did not occur so often close to coast and in high sea states. A four-parameter theoretical formulation was proposed to represent double-peaked spectra and was shown to provide an excellent fit to measured spectra. The average values of the spectral parameters describing the two peaks did not show any clear dependence on significant wave height.
