Abstract
A nonlinear description of drift waves turbulence in a dissipative media with a driven force is built, using a statistic based in a three-modes interaction model. The statistical dynamics of the system is investigated on the basis of the existence of a most physically important triad (MPI triad). Then, the neglected modes are modeled as a white-noise contribution leading to a Langevin equation. A probability density function is obtained for the associated Fokker-Planck equation of the turbulent field. The spectrum cascades and the most physically important triad (MPI triad) are analysed.
