In Star Trek TNG, you hear about some sort of defense back on earth that is supposed to screen out all the bad weather. In the episode "True Q," it is mentioned several times as being capable of preventing/stopping a tornado.
Obviously we can't do this today, and I realize we still don't understand much about how tornadoes even form. We might know what stops them though. What would we need to do to stop/prevent a tornado?
Clarity: This is science-based. I know we can't do this right now, so I'm looking for what we would need to cause. How we cause that is another matter entirely. (For example, maybe a drop in air pressure somewhere solves the whole thing. How we do that comes later.)
Note: This is not a duplicate of this question on how to stop hurricanes. The method for stopping them could possibly be the same (I wouldn't know, hence the question) but the two phenomenons are, to the best of my knowledge, quite different in how they form and behave.
