Abstract

We present a simple physical mechanism for maintaining a steady turbulent state consisting of convection cells and drift waves. In this mechanism, energy is transferred from the unstable short-wavelength drift waves to the longer wave-length convection cells by a decay process. Stationarity is achieved by the viscous dissipation of the convection cell energy. Dual cascading in the convective cell turbulence, as well as the enhanced cross-field plasma diffusion, are examined.
