Study Notes
Tornado Strength
- The Enhanced Fujita Scale measures the strength of tornadoes.
Tornado Duration
- Tornadoes typically last for a few minutes.
Tornado Dissipation
- As unstable atmospheric conditions disappear, the tornado weakens and dissipates.
Water Tornadoes
- Water spouts are tornadoes that occur over water.
Rotating Air
- A mesocyclone is the rotating area of air that can produce a tornado.
Scattered Remains
- Debris is the term for scattered remains of something broken or destroyed.
Tornado Lifespan
- A tornado reaches the end of its life cycle when it dissipates.
Winter Tornadoes
- Tornadoes are less common in winter because of the lack of warm, moist air.
Intended Audience
- The intended audience is likely students or people seeking basic knowledge about tornadoes.
Tornado Travel
- Tornadoes can travel across land for short distances, typically a few miles.
