How are tornadoes and waterspouts different?

Tornadoes and waterspouts are both rotating columns of air that extend from the base of a thunderstorm cloud to the ground or water below. However, there are some key differences between the two.

1. Location

Tornadoes occur over land, while waterspouts occur over water. Waterspouts can form over any body of water, but they are most common in tropical and subtropical regions.

2. Size

Tornadoes are typically larger than waterspouts. The average tornado has a diameter of about 100 meters (330 feet), while the average waterspout has a diameter of about 10 meters (33 feet).

3. Wind speed

Tornadoes can have wind speeds of up to 500 kilometers per hour (300 miles per hour), while waterspouts typically have wind speeds of less than 100 kilometers per hour (60 miles per hour).

4. Damage

Tornadoes can cause widespread damage, destroying buildings and infrastructure. Waterspouts can also cause damage, but they are typically less destructive than tornadoes.

5. Frequency

Tornadoes are more common than waterspouts. In the United States, there are an average of about 1,200 tornadoes per year. There are no reliable statistics on the number of waterspouts that occur each year, but they are estimated to be in the tens of thousands.

6. Lifespan

Tornadoes can last for several minutes, while waterspouts typically last for only a few seconds.

7. Rotation

Tornadoes rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Waterspouts can rotate in either direction.

8. Sound

Tornadoes can produce a loud, roaring sound. Waterspouts typically do not produce any sound.

9. Lightning

Tornadoes are often accompanied by lightning. Waterspouts are rarely accompanied by lightning.

10. Safety

If you see a tornado, you should take shelter immediately. If you see a waterspout, you should stay away from it and keep an eye on it.
