wave age

A measure of the time the wind has been acting on a wave group, either because the wind has been blowing for a finite length of time or because the fetch is limited; usually expressed as a dimensionless number, the phase speed of the peak of the wave spectrum divided by the wind speed or by the friction velocity.
