Abstract
A joint probability density is derived for wavelengths and wave heights. It is asymmetric and depends only on the spectral bandwidth epsilon defined b y Cartwright and Longuet-Higgins (1956). After that a theoretical probabili ty density for wave steepness is obtained. It tends to Rayleigh distributio n as epsilon --> 0. A comparison between theoretical steepness distribution and laboratory experiment result shows good agreement.
