Global Weather-Forming ULF Electromagnetic Nonlinear Vortex Stuctures in the Shear Flow Driven Ionosphere Plasma

Abstract

In the present article the dynamics of generation and propagation of These waves are stipulated by spatial inhomogeneous geomagnetic field. The large-scale waves are weakly damped. The waves generate the geomagnetic field from several tens to several hundreds nT and more. It is established, that planetary ULF electromagnetic waves, at their nonlinear interaction with the local shear winds, can self-localize in the form of nonlinear long-lived solitary vortices, moving along the latitude circles westward as well as eastward with velocity, different from phase velocity of corresponding linear waves. The vortex structures transfer the trapped particles of medium and also energy and heat. The nonlinear vortex structures represent can be the structural elements of strong macroturbulence of the ionosphere main drivers of the electromagnetic weather at ionospheric level.
