Convective cell formation and anomalous diffusion due to electromagnetic drift wave turbulence
Abstract
Convective cell formation and spectral cascade processes due to gravitational drift Alfvén waves are studied using a new type of model equation. Conservation relations are derived and explosive instability is found for systems near marginal finite β stability. This instability also remains when the effects of poor as well as favorable curvature regions are included, i.e., for ballooning modes. The anomalous diffusion due to convective cells and quasi-linear effects are compared.
