THE CORRELATION BETWEEN WIDTH AND MAXIMUM POWER FOR NORTH ATLANTIC WAVE SPECTRA

Examination of discrete spectra of some records of sea waves at two widely separated deep-water sited off the eastern seaboard of the North Atlantic reveals the presence of a good correlation between the widths of time-averaged spectra and the power of their largest harmonics. The spectral width decreases with increasing sea state, but at large wave amplitudes may be regarded as approximately constant.
