Turbulence under rotation forced by inertial waves on the Gyroflow rotating platform

Internal waves can propagate in the bulk of the oceans and atmosphere, due to the influence of the fluid stratification and of the Earth rotation. These turbulent ensembles of waves are expected to play an important role in the oceans and atmosphere dynamics at small scales. The experiment presented in the video allowed the first quantitative validation of the Wave Turbulence Theory for the case of inertial waves in a rotating fluid, a theory which precisely aims at describing the dynamics of ensemble of waves exchanging energy. This validation helps to make Wave Turbulence Theory a potential candidate to improve the models of the turbulent transport at small scales used in global atmospheric and oceanic simulations.
