I like the idea of having hundreds of explosives left in the path of the tornado so when the tornado goes over them they all get sucked into the twister, as they all starting spinning within and get spread out someone pushes the detonator and blows them all up. The resulting explosion throughout the tornado will disrupt it so it dissipates.

Yeah, right!
Someone forgot to tell them that a tornado contains the energy of a small nuclear weapon. Any explosion large enough to actually stop a tornado from striking a populated area would do more damage than the tornado.
Tachy's idea (as usual) is even crazier, as he's added dangerous projectile explosive devices that will be picked up and hurled miles away in every direction. And you might as well throw firecrackers into it for all the good a bunch of little explosions would do. Do 1000 firecrackers blow up an M1A1 any better then one firecracker?
Even if you
did manage to track, target and successfully detonate a large enough explosion to disrupt a tornado momentarily (killing everyone within a mile no doubt), it would reform almost instantly. It's like a whirlpool that forms when two rivers merge; You could disrupt the whirlpool for a moment by tossing a stick of dynamite into it but the in-rushing water would reform it almost instantly. So unless anyone knows of a bomb large enough to disrupt 10 cubic miles of air space without killing everyone in the county and irradiating a storm cell....
People have already thought about doing this. In fact, they've tested it on a small scale in labs. It just isn't practical. Not with explosives anyway, maybe in the future we'll have some kind of electromagnetic weather control, I don't know. Though such a system would likely have to stop a tornado from forming in the first place; once they start they contain an awful lot of energy. More than "concert loudspeakers". Man where do you guys come up with this!?
People talk about stopping hurricanes too, never mind that a hurricane like Katrina would eat up a dozen 10 megaton nukes and burp them out like breakfast. AND we'd irradiate the hurricane with fallout in the process.
