Zonal flow generation in quasi 2D turbulence in magnetised plasmas and rapidly rotating planetary atmospheres — •Andreas Kammel and Klaus Hallatschek — IPP-Garching, Boltzmannstr. 2, 85748 Garching

The interaction between drift waves and zonal flows in plasmas through Reynolds stresses is being examined in great detail using the two-fluid code NLET, thereby studying the structure of the flows, the median zonal flow width, possible stable states and the influence of the geometry of the magnetic field in fusion devices.

In a later stage, the development of a new numerical code for simulating the atmospheres of gas giants is being projected, with the aim of expanding the analysis above to include the hydrodynamic, planetary case, where the geostrophic modes act as the analogon to the drift waves, thereby allowing for a comparison between the two systems.
