  Using electromagnetic particle-in-cell simulations Winske and Daughton [Phys
Plasmas, 19, 072109, 2012] have recently demonstrated that the nonlinear
evolution of a wave turbulence initiated by cold ion ring beam is vastly
different in three dimensions than in two dimensions. We further analyze the
Winske-Daughton three dimensional simulation data and show that the nonlinear
induced scattering by thermal plasma particles is crucial for understanding the
evolution of lower hybrid/whistler wave turbulence as described in the
simulation.
