Abstract
An investigation of the characteristics of wave groups
occurring in five ocean swell trains was undertaken. To
accomplish this, a definition of wave groups and their
properties was developed. It was found that the average
wave group period and the average maximum height in a group
were essentially equal to the spectral period of maximum
energy density and the significant height of a swell train,
respectively. Additionally, the five swell trains investigated
exhibited similar trends in the time variation of
wave group characteristics such as the number of waves in a group, the duration of a group, and the percentage of time
that the groups were present. Finally, wave group measures
such as the wave group period, average maximum height of a
group, and the wave period variability were shown to vary
similarly with respect to wave group duration and the number
of waves in a group.
