No, I would say not. It's not uncommon for a tornado to cause an explosion itself by plowing through a gas station or by tearing power lines loose that then ignite something flammable. In fact, someone caught a video of yesterday's tornado in Oklahoma causing an explosion: http://www.ithacajournal.com/VideoNetwo … ideo||news
The explosion was quite small compared to the size of the tornato, so from that I would agree a surface explosion would do nothing. what about an air burst mid way up, sized to suit the size of the tornado?
I really like this question. I've never been in a tornado, but I have seen tornado weather, and I have also seen those mini dust devils. Those you can stop if you stomp on them-- so what would it take to stomp a tornado? I think you would have to cut through half of the cycle rather than exploding. Come on scientists! I am thinking of a huge iron grid cutting it in half, but that is not very handy.
lumen2light I LOVE this idea! I grew up in NM and we had dust devils that were easy enough to disrupt. I witnessed explosions that occurred during the Joplin tornado, but I think those were caused more by lines being pulled as the tornado chewed through town, so not actually exploding up inside the tornado itself. This reminds me of the concept of the use of dynamite to snuff out an oil well fire. I wonder if it has been tried...I would be interested to learn of any research! If they haven't tried it, then I think now is the time! It seems as if they are growing more powerful and more frequent! Cool idea!
