- The wind speed inside a tornado is about 110 mph/117 km (per hour).
- A tornado’s colour changes, depending where you view it or what the tornado sucks up. This means a tornado could be white, red, blue, brown, grey, orange, yellow and even invisible.
- Tornadoes may not always be visible. If a tornado is visible, the tornado would have low air pressure produced by high wind speeds that mixes the humid air into clouds.
- Tornadoes are most common in Spring and least common in Winter. This is because Spring produces stronger winds while Winter produces the weakest.
- There are many types of tornadoes including waterspouts, dust devils, snow devils, fire wheels and the typical cyclone.
