The problem of genesis and intensification 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.¿ 1997 American Geophysical Union
