We know how tornadoes form: when areas of hot air and cold air mingle, causing rotation. We can even see them form on the radar.
Yet, for all of our technology, we can't stop such events from happening - even though we can cause it to rain by seeding clouds.
But if someone were at the area that a tornado was about to form and was able to introduce an area of super-heated or super-cooled air into the potential tornado, would it destabilize the formation of the destructive whirlwind? Or would doing such a thing cause more of them to form or for them to form more quickly and/ or be more damaging?
