Purpose: to determine the mechanisms of atmospheric-ionospheric interaction, the characteristics of the ionospheric response to the influence of powerful sources of electromagnetic and hydrodynamic disturbances in the lower atmosphere, as well as the mechanisms of wave activity in the Earth's magnetosphere and troposphere-stratospheric interaction in the face of climate change. Research Methods: Theoretical calculations and computer simulation, terrestrial and satellite measurements. Analytical models for penetration of electric field perturbations from the lower atmosphere to the ionosphere have been developed and can be used to study the influence of the most powerful sources of wave activity on the Earth – Atmosphere – Ionosphere – Magnetosphere system. On the basis of the combined statistics of satellite measurements, a new synthetic model of choral waves is created, which realistically reproduces the strong variations of the diffusion velocities and losses of relativistic electrons in the outer radiation zone during the period of geomagnetic disturbances at Kp ~ 3–6. Measurements of carbon monoxide in the mesosphere by a microwave radiometer in Kharkov investigated the effects of stratospheric warming: reversal of zonal wind, oscillations in vertical profiles of CO, zonal wind, and temperature, and correlation of CO oscillations with the influence of planetary waves. The validity of forecasts of anomalous seasonal ozone depletion over the Antarctic when applied to the developed forecast indices is confirmed by the predicted small area and early hole decay in the spring months of 2019. high anticorrelation (r = −0.73).  Product Description popup.authors Yevtushevs'kyj Oleksandr M.
