Electromagnetohydrodynamic Vortices and Corn Circles

  • H. Kikuchi


A new type of large-scale vortex formation is indicated in helical turbulence in terms of hydrodynamic, electric, magnetic, and space charge fields in the presence of an external electric (and magnetic) field. It is called “Electromagnetohydrodynamic Vortices” and is generated as a result of self-organization by pumping out some of the energy of helical turbulence into large-scale motions. The theory is based upon a new set of electromagnetohydrodynamic (EMHD) equations and Maxwell’s equations and a new equation of EMHD vortices is derived. Possible evidence of EMHD vortices in the lower atmosphere has recently been brought by numerous observations of circular symmetric ground patterns in a corn field in southern England.
