CASCADES AND DYNAMO IN FULLY DEVELOPED MHD TURBULEN
Peter Frick
Abstract: The fully developed turbulence is an intrinsic component of any dynamo realizable in nature or laboratory. Fine properties of MHD-turbulence can strongly affect the dynamo process and the structure of large scale processes which force the small-scale
turbulence affect by-turn the turbulent cascades. Two aspects of dynamo and turbulence relationship are discussed: the peculiarities of cascades in fully developed MHD turbulence characterized by high level of helicities and the mean-field effects, provided by small-scale turbulence in magnetic field generation.
