A FULLY SELF-CONSISTENT FLUID THEORY OF ANOMALOUS TRANSPORT IN FARLEY-BUNEMAN TURBULENCE

Existing renormalized theories of E region Farley-Buneman turbulence a re reviewed, and their strengths and weaknesses briefly highlighted. A general framework for a fully self-consistent fluid theory is present ed nest. The new theory includes nonlinear electron inertia, which has been neglected in previous fluid theories. The effects of the nonline ar electron inertia are studied carefully and linked directly to an an isotropic anomalous collision frequency as well as to an anomalous pol arization effect. The new theory indicates that Farley-Buneman wave en ergy is converted into parallel electron energy, owing to the presence of a wave-induced damping rate given by a nu(kw)(parallel to) term. T he theory offers a self-consistent link between electron heating along the magnetic field lines and the anomalous collision frequency due to Farley-Buneman turbulence. This paper focuses on the self-consistent derivation of the anomalous effects and their physical interpretation, followed by a detailed discussion of the energy balance equation.
