Bound infragravity waves are forced by wave-wavenonlinearinteraction of two wind waves, depended only on the swell energy and water depth.
强迫次重力波的形成机制为海浪的波-波非线性相互作用，它仅依赖于海浪和水深的大小。

Using a low order, two-layer baroclinic quasi-geostrophic model, a nonlinear system including the interaction between a thermal forced wave, a transient wave and zonal flow is studied.
The pump wastage and noise brought by pump Brillouin scattering can be described by the nonlinearinteraction of the Stocks wave which is carried by sound wave.
