title: Characteristics of two-dimensional turbulence that self-organizes into vortex crystals
abstract: Experiments have found that freely relaxing turbulence in inviscid, incompressible two-dimensional Euler flows can self-organize into ordered structures-vortex crystals-in which a number N(c) approximately 2-20 of strong vortices form stable, rigidly rotating patterns in a low vorticity background. In this paper we show that N(c) can be roughly predicted from properties of the flows in the early stage of the turbulent relaxation.
