water droplets, dust, dirt, and debris.

- Mature Stage. Tornado on the ground.
- Shrinkage Stage.
- Decaying Stage.

What is the first step of a tornado?
Rising air from the ground pushes up
on the swirling air and tips it over. The funnel of swirling air begins to suck up more warm air from the ground. The funnel grows longer and stretches toward the ground. When the funnel touches the ground it becomes a tornado.

- Strong, persistent rotation in the cloud base.
- Whirling dust or debris on the ground under a cloud base — tornadoes sometimes have no funnel!
- Hail or heavy rain followed by either dead calm or a fast, intense wind shift.
