A modified shell model for rotating turbulence, applied to statistical properties of the rotating turbulence was described. Randomization was observed to play a significant role in correctly modeling the rotation effect. A randomized linear term, which represented the effect of the coherent structures was introduced to the shell model for magnetohydrodynamic (MHD) turbulence. A weak turbulence approximation was used to obtain scaling properties of the energy spectrum in the shell model. The transition from k-5/3 spectrum for weak rotation to k-2 spectrum for strong rotation was also observed, which was predicted by weak turbulence theory.
