A Kids' Guide to Tornadoes

Windy days can really stir things up and make it difficult to hold on to things that are important, like your umbrella or paper from school. Wind can also be pretty scary, too, especially when that wind is a tornado. Known as twisters, tornadoes can tear down a house and can really hurt or even kill people who are in its path. An air purifier or air ionizer can be helpful when people have to seek shelter from tornadoes in basements or in areas that are underground and safe. An air purifier can help clean up pollutants in the air and an air ionizer can help neutralize or get rid of odors that stink. It is important to stay safe and breathe easy during a tornado, but it is just as important to understand it. Tornadoes are amazing and really interesting, too. Even if you don’t live in an area that has tornadoes, it’s really cool to understand how nature works in creating these awesome but deadly storms.


What are Tornadoes?

This is the first thing that kids need to know if they want to learn about tornadoes. During a thunderstorm, wind can rotate at high speeds and reach down from the clouds to touch the ground. These winds are going so fast that they can reach 300 miles per hour! That’s fast! These rotating winds are super strong and they can really destroy big things. For example, the winds from a tornado can pick up and hurl a car or truck! They can even pull huge trees from the ground!

How are They Formed?

Tornadoes are formed because there are certain conditions that are present. One of these conditions is moist or humid air. The moist warm air begins to rise quickly. The air that is rising blows at one speed and in a certain direction. The cold air that is higher above has changed its speed and blows in a different direction. This causes what is called a wind shear. The wind shear starts air rotating in a column. The column of air can get pulled into a supercell, which is a type of thunderstorm. The updraft from this supercell causes the spinning of the column to go faster and faster so that it creates a funnel. The funnel also rotates very fast and touches the ground. When this happens the tornado is formed.

Where are Tornadoes Common?

In the U.S. there is an area called the Great Plains. This area is centrally located and has the correct conditions for tornadoes to form. This area includes states such as Oklahoma, Nebraska, Texas, South Dakota, North Dakota, Kansas, Missouri, Arkansas, and Iowa. People refer to this area as Tornado Alley.x

When are Tornadoes Most Common?

The peak season for tornadoes is from the month of March through the month of May for states in the southern parts of Tornado Alley. In the northern parts, tornadoes peak during the summer months. There are even peak hours for tornadoes! These peak hours are between 3p.m. and 9p.m.
