Tornadoes are vertical funnels of rapidly spinning air. Their winds may top 250 miles mph and can be 50 miles long. Tornadoes are born in thunderstorms.
These violent storms occur around the world, but the United States is a major hotspot with about a thousand tornadoes every year. A tornado forms when changes in wind speed and direction create a horizontal spinning effect within a storm cell. This effect is then tipped vertical by rising air moving up through the thunderclouds. Tornadoes' distinctive funnel clouds are actually transparent. They become visible when water droplets pulled from a storm's moist air condense.

On the wizard of oz, dorothy's house gets moved to oz by a tornado and this is true buildings can be moved by a tornado but I'm not sure they'd go to Oz!
