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

If you take a body of fluid having some angular momentum, like air or water in a bathtub, and draw it toward a center, such as by draining it down a hole, or draining it up with heat, it's going to concentrate its angular momentum in a smaller volume. That's how you get a vortex.

Tornadoes happen when angular momentum of air is concentrated sufficiently in a vortex vertical to the ground. It depends on various factors like updraft and wind shear between blocks of air. People are working hard to understand how they form. Here's some current knowledge.

Whirlpools are vortices of water around the base of the drainage route or other form of force, While tornadoes are vortices of air around the base of a thunder storm. They are quite similar, but the question is where is the tornado leading. The water from a sink whirlpool heads down a drain, so to replicate this effect, the tornado need to "drain" somewhere. Or at least that is my understanding. Someone correct me if I am wrong.
