Abstract
Resonant interactions between a marginally unstable wave and one or two pairs of slightly damped waves in a quasi-geostrophic two-layer flow on a beta plane are investigated. It is found that a system of waves that is stable under strictly inviscid conditions is destabilized by slight viscosity provided the initial energy of the participating waves exceeds a certain threshold value.
