Tourbilons et sillages dans les fluides géophysiques

Abstract : In geophysical fluids such as the atmosphere, oceans, or the Earth's core the presence of rotation and stratification can highly modify fluid motions, even if they are well known in homogeneous fluids. This manuscript presents a few examples where these effects can either stabilise the flow (as in the case of stratified wakes) or destabilise the flow (as in the case of stratified vortices and precession motion). Finally, the problem of mixing in oceans is discussed and a new numerical method is presented which allows to treat the cas of very weak diffusivities.
