Spectral energy transfer of atmospheric gravity waves through sum and difference nonlinear interactions [PDF]
Annales Geophysicae, 2012 Nonlinear interactions of gravity waves are studied with a two-dimensional, fully nonlinear model. The energy exchanges among resonant and near-resonant triads are examined in order to understand the spectral energy transfer through interactions.
