What triggers the development of a tornado?

Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing an updraft. … When it touches the ground, it becomes a tornado.

What two factors are needed for a tornado to develop?

It takes a thunderstorm to produce a tornado but a relatively small number of thunderstorms have all the ingredients to make a tornado. There are four main factors that must be present for a thunderstorm to produce a tornado and these are shear, lift, instability and moisture.

Where do tornadoes develop?

Most tornadoes are found in the Great Plains of the central United States – an ideal environment for the formation of severe thunderstorms. In this area, known as Tornado Alley, storms are caused when dry cold air moving south from Canada meets warm moist air traveling north from the Gulf of Mexico.

What are the steps of a developing tornado?

The four stages of a tornado include: the organization stage, mature stage, shrinking stage and decaying stage. These stages begin because of atmospheric conditions during a thunderstorm. A tornado begins in the organization stage, when it forms through a series of updrafts among cold and warm air systems.

What does a tornado do to a human body?

The wind gets into cavities (eye sockets, nose, mouth, ears) and can do severe internal damage and ghastly mutilations. – In addition to debris impacts, many people are killed/injured from being violently tumbled along the ground or becoming airborne and then falling.

Can a funnel cloud turn into a tornado?

A funnel cloud is a tight rotating column of air (that is often the start of a tornado) that never reaches the ground. Storms can produce funnel clouds, but never produce a tornado. … So a funnel cloud stays up in the sky, and it doesn’t become a tornado until it actually reaches the ground.

What are the 3 stages of a tornado?

The formation and life cycle of tornadoes can be explained in a series of stages:

  • Stage 1 – Storm development. Sunshine heats the ground which in turn heats the air near ground level. …
