Abstract
Based on mathematical models of describing the multidimensional soliton-type structures in complex media (ionospherean
atmosphere, hydrosphere, ionospheric and magnetospheric plasma) the nonlinear dynamics of electromagnetic solitary
vortices and the wave structures have been studied. Nonlinear wave structures can be a purely monopoly vortex, a transverse
vortex chain, and/or a longitudinal vortex path against the background of an inhomogeneous zonal wind, depending on the
shear flow velocity profile. The accumulation of such vortices in the ionospheric medium can generate a strongly turbulent
state. The interaction of soliton type multidimensional structures in the complex media, described by DNSL class of equations
taking into account of dispersive and dissipative effects are studied numerically and interesting results are obtained.
