Project summary

This application concerns the experimental study of electromagnetic and plasma effects in the ionosphere induced by strong atmospheric perturbations and the development of a generation theory of hurricanes and models of the atmosphere-ionosphere interaction. The project is based on the earlier studies of interconnected processes in the Earth’s atmosphere and the ionosphere performed by the team members that can provide a necessary background for description of the transfer of atmospheric disturbances into the Earth's ionosphere. The authors of the project have a great experience in this field and already obtained convincing experimental results that confirm the reality of such coupling. The work plan of the project assumes further development of the theory of hurricane formation in the moist atmosphere, construction of theoretical models of the atmosphere – ionosphere coupling modified by strong meteorological activity, analysis of available satellite data and definition of the ionospheric signatures of hurricane and their application potential for the short-term forecasting and early detection purposes. The main objectives of the project are:

- Joint analysis of available experimental data on electromagnetic (EM) fields and plasma disturbances collected by Russian and the USA satellites over the zones of strong atmospheric perturbations aimed at the identification of the ionospheric signatures of hurricanes at different stages of formation;

- Development of hurricane theory accounting for the phase transitions in moist tropical atmosphere;

- Investigation of the role of planetary wave dynamics in formation of tropical depression and its conversion into a hurricane;

- Derivation of a self-consistent system of nonlinear hydrodynamic equations that governs the dynamics of two and three-dimensional large-scale vortex structures related to different types of waves in the upper atmosphere and the ionosphere;

- Investigation of zonal flows generation by the Rossby type waves in tropical atmosphere and the study of their role in hurricane dynamics;

- Development of new generation mechanisms of the electric, magnetic and plasma disturbances in the ionosphere induced by the hurricane related internal gravity waves (IGW) and acoustic gravity waves (AGW).
