Abstract: A system for preventing damage from tornados and other harmful naturally occurring weather phenomenon uses multiple jet devices which are distributed in a ground array to produce man made tornados. The man made tornados function to divert or stop the natural tornados. Explosive devices can also be used with the man made tornados to stop the natural tornados. The power of the man made tornados and explosives required to tear down the natural tornados can be determined by calculating the threshold energies of the natural tornados. By determining the energy requirements, process for stopping natural tornados can be optimized.
