Abstract: Rotating, stably stratified geophysical fluids —such as the atmosphere and the oceans— support a peculiar type of waves called inertia-gravity waves, which participate in a range of non-linear interactions. These waves play a central role in oceanic mixing and facilitate energy transfers both spatially and across scales, from large-scale forcing by tides and storms to small-scale dissipation through wave turbulence. Accurately parameterizing the fine scales of internal wave turbulence is crucial for closing the oceanic energy budget and for the development of climate models. However, accessing and characterizing this regime in laboratory experiments remains challenging due to the wide separation of relevant scales and the complexity of the governing dynamics. In this talk, I will discuss recent laboratory investigations motivated by these issues and present my experimental journey towards internal wave turbulence.
