Project summary

The Project is directed to theoretical and experimental (laboratory simulation) researches of the completely new conception based on the EMHD nature of intensification of tropical cyclones, hurricanes, and tornadoes. The purpose of these researches consists in revealing of significant detailed features of the intensification process of intense atmospheric vortices and dangerous thunderstorms, and in development of methods and means of their suppression. This Project being successful realized will create the opportunity for developing and designing ground and space facilities capable of suppressing tropical cyclones, hurricanes, tornadoes, and dangerous thunderstorms.

Expected results. This "Project" will ensure opportunity for transfer the problem of suppression and prevention of cyclones, tornadoes, and severe thunderstorms to the practical area, and it will be possible to demonstrate suppression of tropical cyclones, tornadoes, and severe thunderstorms.

Scope of activity (the main Project stages):


1. Development of physical and mathematical models of tropical cyclone intensification on the base of the EMHD model.
2. Development of physical and mathematical model of tornado intensification on the base of the EMHD model.
3. Experimental research (laboratory simulation) of the EMHD model.
4. Development of physical and mathematical models of a suppression method of tropical cyclones, tornadoes, and severe thunderstorms.
5. Laboratory simulation of a suppression method of tropical cyclones, tornadoes, and severe thunderstorms.
6. Development of conception of employment in natural condition simple above-ground and airplane means for suppression of severe thunderstorms and tornadoes.

Technical approach and methodology

Mathematical modeling

Mathematical model of tropical cyclones presents the conventional (for all previously developed models) system of equations (thermodynamic, continuity, motion, water substance, energy). However, to these equations the system of Maxwell's equations which describe an electric and magnetic fields is added. Besides, to the motion equation an electric and electromagnetic forces are added, and to the energy equation the terms associated with an electric field energy of a power mature thunderstorm and an energy of ocean waves inducing by a tropical cyclone are added also. The energy flux in a tropical cyclone is as follows: energy is selected from the ocean in the forms of sensible and latent heat and is transferred with vapor to the troposphere where to this energy the energy of phase transition of water to ice is added. A part of this energy transferred to the electric field energy and an account of action of the EMHD (electromagnetohydrodynamic) mechanism it transforms to the intense rotation motion.

The mathematical model of a tornado differs from the tropical cyclone model in the first instance by the energy equation what is conditioned by absence in tornadoes of the energy flux as in a tropical cyclones: the energy source of a tornado is the electric energy of a power mature thunderstorm.

Laboratory simulation of the EMHD mechanism and suppression method

1. Unlike all published approaches (e.g., T.Maxworthy, Intense Atmospheric Vortices, 1982) in which rotation was provided by rotating of tanks or by tangential input of fluid, we intend to simulate real the EMHD mechanism which develops in a thunderstorm in the negatively charged layer at altitude 5-7 km (what is confirmed by Doppler radar data which show that rotation during tornado and tropical cyclone formation starts in the middle troposphere at these altitudes and than quickly descends to the earth (ocean) surface). One possible scheme of the experiment in this Project will be able to demonstrate rotation of fluid (the primary circulation) at the expense of the EMHD mechanism only.

2.The main aim of the second experiment is to research the possibility of realizing of an electric break-down in a cloud with using of a laser beam, determining of a laser type, and determining of conditions ensuring the break-down.
