Have you ever heard the story of Pecos Beetle, the legendary cowboy who supposedly roped a massive cyclone with his rattlesnake lasso? Or the tale of Dorothy and Toto being whisked away by a tornado to the magical Land of Oz? While these are just fun stories, they give us a glimpse into the incredible power of tornadoes.
Tornadoes, also known as twisters or cyclones, are powerful funnels of spinning air. They can happen almost anywhere in the world, but many occur in the United States, especially in a region called Tornado Alley. This area stretches from South Dakota through Nebraska, Kansas, Oklahoma, Texas, and into Eastern Colorado. Here, over a thousand tornadoes form each year, with winds that can reach up to 250 miles per hour!
Tornadoes don’t just appear out of nowhere. They form when warm, moist air from the Gulf of Mexico meets cool, dry air from Canada. This creates unstable weather conditions. Thunderstorms and big clouds called cumulonimbus clouds start to form. If the storm becomes organized, the warm air rises and cools, causing the clouds to swirl. When a funnel cloud touches the ground, it becomes a tornado.
Tornadoes can be small or stretch nearly two miles wide. They travel across the ground at about 20 miles per hour, but some can move faster than 70 miles per hour. As they move, they can destroy everything in their path, turning houses into splinters, tossing cars like toys, and uprooting trees. Sometimes, hail as big as golf balls falls from the sky, and the sound of a tornado is like a roaring freight train.
It’s hard to predict exactly when and where a tornado will strike, but there are warning signs. Look for dark greenish skies, rotating clouds, and hail. Supercells, which are strong and long-lasting storms, often create the most powerful tornadoes. If there’s a tornado watch, it means conditions are right for a tornado. A tornado warning means a tornado is likely, and you should find shelter quickly, like in an emergency shelter or even a bathtub.
Did you know that tornadoes spin differently depending on where they are in the world? In the Northern Hemisphere, they spin counterclockwise, while in the Southern Hemisphere, they spin clockwise. Tornadoes are also rated based on the damage they cause using the Enhanced Fujita Scale:
Tornadoes are amazing natural events, but they can be very dangerous. Always stay safe and listen for warnings. And remember, if you hear the roar of a locomotive, it might just be a tornado!

Using a clear plastic bottle, water, and a few drops of dish soap, create your own tornado model. Shake the bottle in a circular motion and watch as a mini tornado forms inside. Observe how the vortex looks and discuss how it relates to real tornadoes.
Practice a tornado safety drill with your classmates. Identify safe spots in your school, such as a basement or an interior room without windows. Discuss the importance of having a plan and knowing what to do if a tornado warning is issued.
Look at a weather map showing Tornado Alley. Identify the states that are part of this region. Discuss why tornadoes are more common in these areas and what weather conditions contribute to their formation.
Write a short story about a day in the life of a tornado. Use descriptive language to explain how it forms, travels, and the impact it has on the environment. Share your story with the class and discuss the different perspectives.
Create a poster that explains the Enhanced Fujita Scale. Include illustrations of the different levels of tornado damage and examples of what each level might look like. Present your poster to the class and explain how tornadoes are rated.

Clarendon Learning explores tornadoes. Legend has it that Pecos Beetle, the toughest Texas cowboy, took his lasso made from a rattlesnake and roped the biggest, meanest cyclone ever, riding it until it got so tired that it petered out. The story is told about how Dorothy and Toto were picked up in their house by a tornado and dropped over the rainbow in the Land of Oz.
These stories may be tall tales and fun to tell around the campfire, but they closely describe the power and fury of one of nature’s most terrifying events: the tornado. Tornadoes, also known as twisters or cyclones, are vertical funnels of rapidly spinning air. While they can occur almost anywhere in the world, a significant percentage happen right here in the United States.
Welcome to Ground Zero: Tornado Alley. From South Dakota down through Nebraska, Kansas, Oklahoma, Texas, and over to Eastern Colorado, this is where many tornadoes in the U.S. occur—more than a thousand a year—with vortex action spinning up to 250 miles per hour. Being in the vicinity of an active tornado is no place you want to be unless you’re a storm chaser. They chase thunderstorms to catch the actual birth of a tornado, which is dangerous business.
So, where do tornadoes come from? They don’t just pop up out of the ground. Here’s what happens: when warm, moist air moving up from the Gulf of Mexico meets cool, dry air coming down from Canada, a very unstable weather pattern develops. Thunderstorms and cumulonimbus clouds gather. If the storm pattern remains random and disorganized, scattered storminess will be the only result. But if the storm pattern is more organized, as rising warm air cools, the clouds begin to swirl. More warm air is sucked up from the ground, and a funnel cloud begins to take shape. If it touches the ground, it’s a full-on tornado.
A tornado may be a few feet across or up to nearly two miles wide. It may be a waterspout, a landspout, or a dust devil. They move along the ground at about 20 miles per hour, sometimes faster, with some being clocked at more than 70 miles per hour. They can shred everything in their path—houses become splinters, cars and trucks are tossed about like toys, and trees are uprooted. Hail the size of golf balls may begin to fall from the sky. The sound is unmistakable, like a roaring freight train, but there is no locomotive.
The life expectancy of a tornado is about six to ten miles, though some have traveled much longer distances, leaving a swath of destruction in their path. It’s very difficult to predict precisely when and where a tornado will strike; however, dark greenish skies, rotating clouds, and hail are good signs. Supercells—tenacious and long-lasting storms—create the most powerful tornadoes.
The emergency broadcast system may issue a tornado watch, indicating that conditions are right for tornado weather, or a tornado warning, meaning that a tornado is likely and you may have only 15 minutes to react and seek appropriate shelter. Throughout Tornado Alley, there are many emergency shelters prepared for this event, or you may have to seek the protection of a bathtub.
Here’s an interesting piece of science: in the Northern Hemisphere, a tornado spins counterclockwise, while in the Southern Hemisphere, tornadoes spin clockwise.
Tornadoes are graded as weak, strong, or violent, and they are rated based on the damage they cause using the Enhanced Fujita Scale:
– F0: Light damage (a weak storm)
– F1: Winds up to 112 miles per hour (moderate damage)
– F2: Winds up to 157 miles per hour (considerable damage, a strong tornado)
– F3: Winds up to 206 miles per hour (severe damage)
– F4: Winds up to 260 miles per hour (devastating damage, considered a violent tornado)
– F5: Winds over 261 miles per hour (incredible damage)
A tornado is an amazing phenomenon, and remember, if you hear the roar of a locomotive, it may not be a train.
