Two-dimensional (2D) turbulence is characterised by essentially different dynamics than ‘ordinary’ three-dimensional turbulence well-known from daily experience. In particular, the absence of vortex stretching in 2D turbulence results in the presence of the so-called inverse energy cascade. The inverse energy cascade manifests itself by a flux of kinetic energy from small to large scales in the flow, and supports the emergence of long-lived and weakly dissipative coherent structures.
The organizers intend to bring together scientists from various disciplines, such as fluid mechanics, meteorology, oceanography, and plasma physics, and to provide a platform for the exchange of knowledge and ideas in the field of quasi-2D turbulence. A series of more didactical lectures will be given on outstanding issues in (quasi-)2D turbulence and its application in meteorology and oceanography. The topics cover recent significant developments in the theory and modeling of 2D turbulence, experiments on (quasi)-2D turbulence, 2D turbulence in confined domains, active and passive tracers dynamics in 2D turbulence, Lagrangian dispersion in turbulence affected by buoyancy and/or rotation, and the effects of non-uniform background vorticity on 2D turbulence.
