Tornadoes

Zoe Suydam & Megan Kim

What, How and Where?

Tornadoes are funnel shaped clouds that extend from a thunder storm with winds that can get up to 300 mph and that can have damage paths up to 50 miles. Tornadoes usually move south-west to north-east with average speeds of 30 to 70 mph. Water spouts are tornadoes that move over water.
Tornadoes are most common in the US but can happen any where, in the US they most commonly happen along tornado ally, which is east or the rocky mountains. Tornadoes can happen any time but most commonly happen between 3-9 pm during the spring and summer.
Tornadoes form from the hot and moist air of the Gulf of Mexico and the cold and dry air of Canada and when they meet they create an unstable atmosphere that swirls and creates a tornado. Tornado ally creates so many tornadoes because it has the ideal conditions of the middle planes creating heat.


Tornado facts

Tornadoes Impacts

We've all seen The Wizard of Oz where Dorthy got swept up into a tornado storm and ends up in Oz, but tornadoes can cause a lot of damage including flying debris, hail damage, and deaths. Buildings can be completely destroyed and the flying debris can cause injuries and even death. One of the oncoming signs or tornadoes is hail, which can cause damage to houses and cars.
The 1896 St Louis- east St. Louis Tornado is one of the most damaging tornadoes. It was an F4 tornado and because of its location there were 225 deaths and over 1000 injuries, and more than $10 million in damage.
The Tri-State, March 18th 1925, was the most damaging tornado in history, it was an F5 spanning over 220 miles and going 60 miles per hour. Killing 695 people and injured 2027 people, the tornado caused $16.5 million in damage it is the most destructive tornado in history.
Tornadoes, like all natural disasters have a relief fund, theirs is called LDS Philanthropies helps over 50 countries throughout the US. There are also the UN Peace keepers, Red Cross, and many others.


Tornado Equipment

The enhanced Fujita scale is a scale that decides how damaging a tornado is, it goes from an EF0, which is no damage, to a EF5 which is the most damaging. This scale includes wind speed and incorporates 28 damage indicators.
Some effective technology used to predict tornadoes are the Doppler radar, infra sound detectors, lightning imaging sensors, and multiple- antenna profile radar to detect formation, and many more others.
