✦ Synopsis

The universality in turbulence are studied in this paper. In the previous paper, we succeeded in studying the system described by the Kuramoto-Sivashinsky equation statistical mechanically. In this paper, it is shown that the turbulence described by the two-dimensional coupled map lattices has di erent statistics between the short time regime and the long time regime. We show that the behaviors of the two di erent regimes have the same characteristics as those of the Kuramoto-Sivashinsky equation.

We review some ideas about the physics of small-scale turbulent statistics, focusing on the scaling behavior of anisotropic uctuations. We present results from direct numerical simulations of three-dimensional homogeneous, anisotropically forced, turbulent systems: the Rayleigh-BÃ enard system, the
