Abstract. The problem of genesis and imensification of tropical cyclones, hurricanes, and tornadoes is highly important in meteorology and to date has not been solved. At the same time, practically all researches made concerning these phenomena fail to take into account that the origin and intensification of tropical cyclones, hurricanes, and tornadoes take place under conditions of an abnormally strong electric field which together with electromagnetohydrodynamic interaction occupies a key position in the intensification process. The detailed description of the electromagnetohydrodynamic model explaining the processes of energy conversion in tropical cyclones, hurricanes, and tornadoes is presented. 1.IntroductionIt has been over 150 years, starting, perhaps, from the research performed by Hare [1837], since the problems related with ascertaining the nature of tropical cyclones, destructive hurricanes, and tornadoes were first discussed, and they still remain a subject of intense attention for many specialists engaged in studies of these rather complex phenomena of nature.By carrying out multiple and systematic studies of these phenomena in recem decades (for obvious reasons only a minor pan of these studies are cited in this article) and using satellite, aircraft, sound, and ground-based observation facilities extensive statistical data have been accumulated and considerable progress has been achieved in revealing factors which determine the genesis of these formidable natural phenomena. Considerable research effort has been directed to finding out the causes which result in intensification of these vortices and building mathematical models of them as well as to simulating them in laboratories.As for tropical cyclones and hurricanes, the above given analysis of their origin and development has not yet given an exhaustive answer in terms of nature but, nevertheless, it has helped to disclose some factors which are of primary significance for the process of intensification and they are as follows' power supply to tropical cyclones and hurricanes at the expense of sensible and latent heat of moist air lifted upward from the ocean surface, the secondary circulation in the vertical plane, It might be a paradox, but an overwhelming majority of researches made lately in analyzing the intensification processes of tropical cyclones, hurricanes, and tornadoes have considered thermodynamic, hydrodynamic, heat transfer processes, and aqueous phase change only, taking no account of processes occasioned by the action of an abnormally strong electric field. Meanwhile, the cloud structures of tropical cyclones, hurricanes, and thunderstorms forming a tornado display abnormal electrical properties obviously observed nowhere else in nature. So, for ex _ample, the maximum potemial gradient values reach 105-106 V m 4, while the total electric charge of a hurricane is many times as large as Eaxth's total electric charge. For all that, the values of electric and electromagnetic forces could happen to be greater than all other actin...

Abstract. Tropical cyclones and storms, hurricanes, powerful thunderclouds, which generate tornadoes, destructive extratropical cyclones, which result in catastrophic floods, are the powerful cloud systems that contain huge amount of water. According to the hypothesis argued in this paper, an electric field coupled with powerful clouds and electric forces play a cardinal role in supporting this huge mass of water at a high altitude in the troposphere and in the instability of powerful clouds sometimes during rather a long time duration. Based on this hypothesis, a highly effective method of volume electric charge neutralization of powerful clouds is proposed. It results in the decrease in an electric field, a sudden increase in precipitation, and subsequent degradation of powerful clouds. This method, based on the natural phenomenon, ensures the prevention of the intensification of tropical and extratropical cyclones and their transition to the storm and hurricane (typhoon) stages, which makes it possible to avoid catastrophic floods. It also ensures the suppression of severe thunderclouds, which, in turn, eliminates the development of dangerous thunderstorms and the possibility of the emergence and intensification of tornadoes.
