"WebThe spectral moment is just the variance of the surface and hence which is the reason for the notation. The "old" definition of the significant wave height was the mean of the one third largest waves in the sea, - a definition which is not very easy to apply! The significant wave height is without doubt the most important sea state parameter. " - Spectral wave period
