that would imply every single tornado is actually a waterspout, because the factor of it is tornadoes are only visible because of the clouds (which are made of rain.) Plus, that's not what a waterspout is, a waterspout is formed over a body of water, thus "spouting" out of the water, thats why landspouts are called land spouts, they form from the ground. not the clouds.
Note: Tornados start as waterspouts that the water starts circling and rising to tornado until it surns to air
this is quitew inaccurate, the smke is supposed to be going upwarsds in a tornado, not down. Still cool :D +1
You spelled simulation wrong.
