Interplay of Boundary and Bulk Dynamics in Rotating Turbulence Driven by Libration

Explore a 51-minute lecture from IPAM's Rotating Turbulence Workshop where Michael Le Bars delves into the complex dynamics of rotating turbulence driven by libration. Discover how rotating turbulence typically manifests through geostrophic vortices and inverse energy cascade, while learning about an alternative regime called inertial wave turbulence that creates three-dimensional flows with downscale energy cascade. Examine how planetary interiors experiencing libration - periodic changes in spin rate - can generate bulk inertial waves through various coupling mechanisms with boundary layers. Gain insights from theoretical, experimental, and numerical studies that investigate different turbulent states in rotating, librating systems and their implications for planetary interiors. Understand how this research challenges current theories about dissipation, mixing, and dynamo mechanisms in planetary contexts.
