Karazin popup.description2 An object of study is the parameters of ionospheric plasma and near-Earth space during natural disturbancies. The work aim is to identify the properties of the ionosphere as a component of non-linear dissipative lithosphere - troposphere - ionosphere - magnetosphere system. The research methods are the geophysical observation, statistical analysis, empirical and theoretical modeling. On the basis of the analysis of geophysical daily data for 2007-2015, the stable nature of the relationship between geospheres is established. This indicates that the Earth and its shells form the common open nonlinear dynamic hierarchical system, whehe interaction is possible due to energy-weak (trigger) mechanisms. Such permanent associations, even with relatively small amplitudes of effects, may provide the forming long-term trends in changes of the ionosphere parameters and other geospheres as well. These changes may occure under the influence of anthropogenic factors that are not taken into account by existing linear (quasi-linear) environmental models. The consideration of the nonlinear interaction of geospheres is the necessery condition for the correct estimation and the forecasting of environmental changes. The obtained results may be used for developing the empirical and theoretical models of the ionosphere, for the estimation of the ecological consequences of natural and anthropogenic processes in the human condition. These results will be used in the educational process. Product Description popup.authors І. Г. Захаров І. С. Мартиненко А. М. Цимбал О. М. Гоков О. Ф. Тирнов Ю. П.
