Tornadoes

How a tornado happens
- A tornado needs three different types of air in a particular order. Near the ground it is warm with south winds. In the upper atmosphere there is colder air and west winds. Because air is less dense at the bottom air will start to rise this is called instability.
- The second part is changing wind speed with height this is called the wind shear and causes rotation.
- Last thing you need is a layer of hot, dry air in between the cold this s makes it take its . It pushes up and makes strong updrafts making it roatate thus a tornado.

What is the impact on humans? The environment?
Depends on size of the tornado F1 to F5. F2 and up cause the most property damage. Now that there are improved weather systems houses are built to withstand tornadoes . Flying debris is responsible for the most environmental damage . Winds pick up and carry dirt and dust from farming lands and leave them else were.
Humans:
Injuries occur mainly from flying debris. Many people die because of improper shelter and being trapped in the aftermath. But because of advanced weather systems there are fourteen to sixteen minutes in advance.
