Nonlinear electrostatic WAVE structures in collisional ionospheric plasma
The theoretical model of the formation of nonlinear electrostatic wave structures is considered on the basis of the magneto-hydrodynamic system of the equations (MHD) of moving charged particles in ionospheric plasma. The evolutionary equation for nonlinear stationary structures moving orthogonally to the magnetic field and electric field is received. For the solutions corresponding to the stationary wave structures the parametric sphere of the space where the formation of nonlinear structures of the nonlinear collision shock wave type is investigated. The threshold values of movement speeds, of electron drift speeds and the scales of these structures are defined.
