Stably Stratified and Rotating Turbulence

The main motivation for SIG14 is to study and understand the role of the body force effects on turbulence, especially stratification and rotation. These are fundamental in environmental non-homogeneous flows, for example to predict diffusion of pollutants in the Ocean and Atmosphere.  Environmental fluid dynamics produces specific vortical and helical complex flows which are very difficult to predict.

The statistical description of direct and inverse cascades in turbulence at different scales is also one of the fundamental topics covered together with more applied related topics such as environmental hazards as dense gas dispersion or gravity and turbidity currents. New measurements and methods of analysis taking into account the topology of the particular flows will focus on atmospheric, ocean and astrophysical turbulence measurements. Eulerian and Lagrangian techniques, diffusion, stirring, mixing, planetary boundary layer studies, etc.

All lines of research will be combined in a complementary fashion, such as: Theoretical and Field studies, Earth observation, Numerical and Physical Experiments.

Main topics of SIG14

  • Body forces, 3D and 2D Turbulence, Environmental Turbulence.
  • Mixing and Dispersion in the Ocean and Atmosphere.
  • Pollution detection, Turbulence Cascades, Intermittency, non/locality.
  • Atmospheric/Ocean Science, Environmental Hazards.
  • Experiments in Rotating-Stratified flows.
  • Numerical parametrizations of body forces
