Discrete resonant Rossby/drift wave triads: an explicit parameterisation and a fast direct numerical search algorithm

Umar Hayat, Shahid Amanullah, Shane Walsh +1

We report results on the explicit parameterisation of discrete Rossby-wave resonant triads of the Charney-Hasegawa-Mima equation in the small-scale limit (i.e. large Rossby deforma…
