Tornadoes in real-life have very complex behavior, so you would need to develop a whole system to control it's behavior.

Out of the box you can use built-in volumetric clouds feature that will allow you to create a custom cloud shape by using 3D texture (I believe in Houdini you can use Volume Slices and to export them vertically arranged). More info on this is available in the following tutorial: https://developer.unigine.com/en/docs/latest/videotutorials/essentials/clouds?rlang=cpp

However, that's probably wouldn't be enough to have a good looking tornadoes. Some additional custom volumetric rendreing would required (that's currently not possible to make).

Maybe for some simple cases you can use mesh with custom material and particles.

Thanks!
