The ion cyclotron turbulence theory of rotating plasmas in crossed fields is considered. This turbulence is due to the instability of short-wavelength modified ion cyclotron waves (ion Bernstein modes). This instability is caused by an azimuthal drift of electrons with respect to ions with a relative velocity below the ion thermal velocity. The generalized weak turbulence theory and quasilinear theory as well as the strong turbulence theory accounting for cyclotron resonance broadening due to the random walk of ions in a perturbed electric field are constructed. Cylindrical waves serve as elementary perturbations of electrostatic potential in these theories. Induced scattering of ion cyclotron cylindrical waves on bare ions is shown to be the main mechanism, totally suppressing higher-order mode ion cyclotron waves in the weak-turbulence regime at the first nonlinear stage of the development of the instability. Nonlinear ion cyclotron resonance broadening is a possible saturation mechanism for the lower modes. A heating rate for the ions is determined.
