Weather Wise Kids: How Do Tornadoes End?

Drake Waters of Hesse Elementary in Savannah wants to know… “How do tornadoes end?”

Well Drake, just like all other weather systems, tornadoes have a beginning and an end. Only problem is, we (scientists) don’t fully understand how exactly tornadoes form, grow or fall apart. Researchers are still trying to solve the tornado puzzle. For every piece that seems to fit, scientists often find new pieces to study.

But there are two main theories.

First, some believe a tornado falls apart once it moves over colder ground. The tornado becomes weak and rope-like.

The other main theory is that tornadoes end when the clouds above start to break apart.

Some tornadoes only last seconds. Others can last much longer. They come in many shapes and sizes.

The longest lasting single tornado in U.S. history is called the Tri-State Tornado. This extreme twister roared through parts of Missouri, Illinois and Indiana on March 18th of 1925.

It was on the ground for 3 1/2 hours. It killed an estimated 695 people and injured more than two-thousand. The Tri-State Tornado is still the deadliest single tornado in United States history.
