Internal waves are waves that propagate in rotating and/or stratified fluids (i.e. fluids in which density is a function of depth) such as geophysical fluids like the atmosphere or the oceans. They have recently been the subject of numerous studies due to their central role in oceanic mixing processes, which are essential for parametrizing climate models. These waves contribute to energy transfers, both spatially (through the entire stratification, from the ocean surface to the abyss, for example) and across scales (from large forcing scales to small turbulent dissipative scales). Due to the particular properties of these waves, the modalities of these transfers are still poorly understood. In this talk, I will discuss different types of interactions that ultimately enrich the frequency spectrum to eventually reach a wave turbulence regime.
