Waves and turbulence in geophysics and space physics and anomalous dissipation

Session ID#: 22881

Session Description:
Properties of geophysics and heliophysics depend on complex cross-scale interactions between the waves they support (inertia-gravity, (Kinetic) Alfven, whistler), and nonlinear eddies. Can the flow be treated as a superposition of quasi-linear waves at any scale? How does resolving small-scale dynamics affect large-scale turbulence? Indeed, breaking waves generate flow variability and can in turn affect the overall circulation, posing difficulties to subgrid-scale modeling and leading at times to poor predictive value. In this session, we invite contributions on this vast topic stressing the commonality of properties within diverse contexts, the key role of anisotropy and the variation of scaling laws with dimensionless parameters. Applications range from the atmosphere, troposphere and mesosphere, to the ocean and to space weather, e.g. in the Solar Wind and the magnetosphere, with a particular emphasis on anomalous dissipation and mixing, the formation of coherent structures and fronts and their destabilization, as well as extreme events.
