| Abstract: | Three probability density functions are derived for a unidirectional and spatially homogeneous Gaussian wave field in the light of Sun Fu's theoretical frame about the statistical distribution of wave parameters of 3 D wave field They are the joint distribution of wave heights and wavelengths, the distribution of wavelengths and the distribution of wave steepness Based on these distributions the definitions of characteristic steepness, including mean steepness and sea state steepness are studied The strict physical implication of the now used definition of sea state steepness is revealed At last, the relationship of sea state steepness with wind velocity and wind fecth is given |

| Keywords: | wavelength wave steepness characteristic steepness statistical distribution |
