This may not be a great question. But whenever you drain water, a small whirlpool happens, obviously. This got me thinking...

Can we model tornados with this effect, would it even be beneficial?

Clearly there are some similarities between the two phenomena. I guess you should think about matching dimensionless numbers that describe the relative importance of forces to be able to do this. Maybe this matching is not possible?! – Michiel Mar 9 '13 at 21:56
