  It is well known that a wave can generate other waves (due to
  nonlinearity of continuous media). This talk is about a different
  situation, when a wave suppresses other waves.

  It is shown that a train of long waves can suppress a short-wave field
  due to 4-wave resonance interactions. These interactions lead to the
  diffusion (in the Fourier space) of the wave action of the short-wave
  field, so that the wave action is transported to the regions of higher
  wave numbers, where it dissipates more effectively.
