Anisotropic Dispersion in Rotating Fluids. A Laboratory Model of Large Scale Flows
The variation of the Coriolis parameter with the latitude (beta effect) strongly affects the turbulent inverse cascade. In fact, when this effect holds, energy is preferentially transferred towards zonal modes. The consequent emergence of flow structures along the zonal direction can strongly impact transport and modify both zonal and meridional scalar diffusion. We performed a detailed analysis of Lagrangian tracers dispersion on rotating flows simulated in laboratory.
