Why have scientists not developed a practical method for controlling tornadoes?

Scientists have not developed a practical method for controlling tornadoes primarily because there is very little scientific understanding of their complex dynamic structure. While it has been speculated that tornadoes could be influenced by firing rockets into them to alter their temperature or electrical properties, these schemes lack scientific confidence due to the limited knowledge of how these storms function.12

Unlike some other forms of weather modification, such as cloud seeding for precipitation or hail suppression, no actual attempts have been made to control tornadoes. Because so little is known about the specific mechanisms that drive these violent storms, few scientists believe that current intervention methods would be effective. Consequently, very little research has been devoted to the practical modification of tornadoes.21
