The nonlinear interaction of the drift cyclotron and lower‐hybrid‐drift modes is examined. A renormalized equation for the drift cyclotron ion response is derived and solved. Lower‐hybrid‐drift modes comprise the turbulent background. For levels of lower‐hybrid‐drift turbulence ofe&Fgr;/Ti∼(me/mi)1/2(&rgr;i/L)3/4, the growth rate of the drift cyclotron mode begins to be reduced by ion cyclotron resonance broadening, which is the dominant nonlinear effect.
