Coupled triads in the dynamics of internal waves: Case study using a linearly stratified fluid

Coupled triads (two sets of resonant triads with one member in common) can arise in linearly stratified fluids. Such coupling may induce modulation instabilities which are otherwise absent for component triads in isolation themselves. Long wavelength instabilities will imply the occurrence of internal rogue waves which may attain amplitudes much larger than their surface wave counterparts.
