Turbulence and two-dimensional channel turbulent flow in the system rotation are explained. Rossby number is the most important parameter in a rotating fluid. The effect of rotation is indicated by the ratio of the background vorticity to the shear vorticity in a rotating turbulent shear flow. Rotation such that shear becomes cyclonic is stabilizing, but anticyclonic rotation is destabilizing for low rotation rates and restabilizing for higher.
Fundamental relations induced through Navier-Stokes equations and a decaying turbulence in the presence of rotation are discussed. For a two-dimensional channel flow the laws of velocity distributions are also discussed by the dimensional consideration with experimental results.
