Instabilities and transition in three-dimensional flows with rotation ANISOTROPIC ENERGY TRANSFERS IN DECAYING ROTATING TURBULENCE

In the presence of a background rotation, a situation which is relevant for most geophysical and astrophysical flows, the energy cascade from large to small scales is modified by the Coriolis force, resulting in a gradual colum-nar structuring of the turbulence along the rotation axis. In the limit of large rotation rates, turbulence tends to become two-dimensional —but still three-component (2D-3C)—, in agreement with the Taylor-Proudma
