The possibility of large-scale planetary waves (wavelength 1000 km and more) and related nonlinear distributed hurricane structures propagating in the Earth ionosphere has been investigated. The interaction of inductive electric current and spatially heterogeneous geomagnetic field is taken into account. The study on the basis of the dynamics and magnetohydrodynamic equations of the developed fluids is performed by both analytical and numerical methods. Constantly acting global factors such as spatial heterogeneity and curvature of a geomagnetic field have been shown to be the source of planetary ultraviolet (UPS) electromagnetic wave generation in the ionosphere.
1) The theory of fasting water has been developed for the disturbance propagating in the E-layer of the ionosphere. For such a weakly ionized plasma, a nonlinear generalised Charny-Obukhov equation describing the propagation of magnetized Rosby waves is derived. These waves are generated by a dynamo-electric field and are a generalization of tropospheric Rosby waves in a spinningly heterogeneous geomagnetic field in a rotating ionosphere.
2) It is shown that the mechanism of self-organization as spinning vortex structures is the joint compensation of the interaction of wave dispersion in the wave equation and convective nonlinearities represented by scalar and Poisson brackets. The resulting dissociated structures are anisotropic and represent a combination of symmetric hurricanes superimposed on dipole hurricanes.
3) Stationary nonlinear solutions for synoptic scale concerns are obtained analytically.
4) It is established that the so-called ionospheric layers E and F move. Fast and slow low frequency electromagnetic planetary waves.
5) A closed-loop system of nonlinear, privately produced differential equations describing the propagation of three-dimensional (x, y, z) planetary-scale UDS electromagnetic waves in the ionosphere is obtained.
