eli5: How do tornadoes form?

386 views

Some of my co-worked are located in Tornado Alley and I’ve been wondering how tornadoes form and die. I have never seen one in person (and I don’t want to). How is is different form a dust devil? I saw a dust devil form across the street and stop once it hit my garage door where I was standing. I just froze and didn’t know what to do.

I’ve seen a fair number in the UK (just funnel clouds) ie not touching the ground, often slanted (not straight up and down). I learned somewhere once that Tornadoes can form when a horizontal ‘rotor’ is churning in a thundercloud, warm air grating over cold air, one end of this rotor makes it to the ground and all hell breaks loose. Not gospel but s theory I heard, which correlates with all the slanted FC’s I’ve seen.
