A hamiltonian derivation of interaction equations for Rossby waves

• The mode coupling equations for Rossby waves in a bounded periodic channel are derived by means of a Hamiltonian method. The streamfunction is used as field variable and we need not introduce Clebsch potentials or a lagrangian description. The Manley-Rowe relations follow from general hamiltonian theory.
