Courses on turbulence generally begin with the delicate question of defining turbulence. As usual for important concepts, a clearcut definition is not possible, and the problem is still worse for two-dimensional (2D) turbulence. It can be said that turbulence is a flow which is disordered in time and space. The following properties more precisely characterize turbulence, see for instance Lesieur [64].
