Abstract — The hydrodynamic system that admits the development of internal wave attractors under biharmonic forcing is investigated. It shown in case low amplitude external pattern consists two interact between themselves only slightly: total energy equal to sum energies components with high accuracy. In nonlinear more complex way which leads a cascade triad interactions generating rich set tim...

In this paper we construct a new solution which represents Pollard-like three-dimensional nonlinear geophysical internal water waves. The includes the effects of rotation Earth and describes wave exists at all latitudes across propagates above thermocline. is provided in Lagrangian coordinates. process derive appropriate dispersion relation for waves stable stratification discuss particles path...
