| 摘 要： | Studying the relationship between wave steepness and wave age is important for describing wind wave growth with energy balance equation of significant waves. After invoking the dispersion rela- tion of surface gravity wave in deep water, a new relationship between wave steepness and wave age is revealed based on the “3/2-power law” (Toba, 1972), in which wave steepness is a function of wave age with a drag coefficient as a parameter. With a given wave age, a larger drag coefficient would lead to larger wave steepness. This could be interpreted as the result of interaction between wind and waves. Comparing with previous relationships, the newly proposed one is more consistent with observational data in field and laboratory.

| Abstract: | Studying the relationship between wave steepness and wave age is important for describing wind wave growth with energy balance
equation of significant waves. After invoking the dispersion relation of surface gravity wave in deep water, a new relationship
between wave steepness and wave age is revealed based on the “3/2-power law” (Toba, 1972), in which wave steepness is a function
of wave age with a drag coefficient as a parameter. With a given wave age, a larger drag coefficient would lead to larger
wave steepness. This could be interpreted as the result of interaction between wind and waves. Comparing with previous relationships,
the newly proposed one is more consistent with observational data in field and laboratory.
