Start here: main parts 5

Tornado A fast-spinning column of air that reaches the ground.
Debris cloud Dust and debris lifted where the tornado touches the ground.
Wall cloud A block of cloud lowered from the storm's base. Tornadoes may form under it.
Updraft Rising air in the storm. It tilts the spinning tube upright.
Funnel cloud A spinning funnel that has not touched the ground. Once it touches down, it is a tornado.

A tornado under its storm 4

Tail cloud A tail-shaped cloud that reaches from the rain toward the wall cloud.
Mesocyclone The rotating part of the storm, much wider than the tornado.
Rear flank downdraft Sinking air on the back side of the storm. It wraps around the rotation.
Inflow Warm, moist air flowing into the storm near the ground.

How it starts 2

Wind shear Wind that changes speed or direction with height.
Rotating tube of air A level tube of spinning air, set rolling by wind shear.

Under the storm

The tornado is the funnel that reaches the ground, with a debris cloud around its foot. It hangs from the wall cloud, a block of cloud lowered from the storm's base. Curved arrows mark the mesocyclone, the rotating part of the storm. Warm, moist air flows in along the ground, and the rear flank downdraft sinks behind.

How it starts

One way a storm can start to rotate: wind shear sets a level tube of air spinning, and the storm's updraft tilts it upright. A funnel cloud may then lower from the cloud. When it touches the ground, it is a tornado.

To label a diagram of a tornado on paper, print it blank. The labeled print is the key.

Questions and answers

What are the parts of a tornado?

The tornado itself is a rotating column of air that reaches the ground, often seen as a funnel. A debris cloud surrounds its foot. Above it are the wall cloud and the mesocyclone, the rotating part of the storm.

What is the difference between a funnel cloud and a tornado?

A funnel cloud is a rotating funnel that hangs from a cloud and is not in contact with the ground. Once it touches the ground, or a debris cloud appears beneath it, it is a tornado.

How does a tornado form?

Scientists do not fully understand it. Most tornadoes come from supercells, thunderstorms with a rotating updraft. Wind shear can set a level tube of air spinning, and rising air tilts that rotation upright.

What is a wall cloud?

A wall cloud is a block of cloud lowered from the rain-free base of a thunderstorm. Tornadoes may develop from a wall cloud, and some wall clouds rotate.
