A third possibility, is that these are waves which can be
described by the non-linear Schrödinger equation:
The
non-linear S.-E. has many solutions. Under the right conditions,
so-called "breather" waves can develop. In
a regular and near uniform wave sequence, one peak can absorb wave
energy from its neighbors and grow much larger than the background
waves. The figure below shows the evolution of such
a wave distribution with one peak gaining significant amplitude from
nearby peaks (time evolution is bottom to top):
