Description This study attempts to resolve a mix-up between a physical process and its mathematical interpretation in the context of wind waves on ocean surface. Wind generated wave systems, are conventionally interpreted as a result of interaction of a number of sinusoidal component waves; a consequent idea arising out of Fourier analysis. It is hypothesised that a sea state which is always nonlinear to various degrees is a result of interaction, both linear and nonlinear, between nonlinear component waves of different nonlinear intensities and their groups. The intensity (nearly linear to high) and dominance of a particular component wave depend on the stage of development of sea state, wind structure and environmental conditions like currents, bottom topography and other wave systems
