The paper provides new insights and new results for resonance triads of Rossby waves which are described as solutions of a Diophantine equation: we have derived a new description using undirected graphs and we have proven their most essential properties as well as a suitably complementary description by fourth degree curves – bicircular quartics.
Key words: Rossby wave, Charney-Hasegawa-Mima equation, resonant triad, Diophantine equation, undirected graph, bicircular quartic
