| Zusammenfassung |
| By using a Hamiltonian method, non-linear three-wave
interaction in a class of systems related to the shallow water model is considered and a
general coupling coefficient is presented. In the special case where two inertial waves
and one Rossby wave interact resonantly, it is found that even a very small shear of the
background velocity can be important in the interaction process. The stability of the
system is considered by using a pseudo-energy method. Some implications for the dynamics of
atmospheric flows are pointed out. |
