Abstract
Evolution of weak anisotropic 2D turbulence in a two-layer medium is considered by way of an example of geostrophic turbulence. Numerical experiments with a kinetic (energy transfer) equation confirm that a powerful barotropic nearly zonal flow is always generated, whereas its baroclinic component is typically suppressed. For certain initial conditions a considerable large-scale baroclinic meridional anisotropy is excited.Keywords
