Visible parts of a tornado include the condensation funnel, which is formed by the pressure drop condensing water vapor, and the debris cloud which is caused by the winds of a tornado picking up soil and/or debris. The tornado itself is a rapidly spinning vortex of air with a powerful updraft. Some tornadoes also have a downdraft in their centers which forms a calm, clear area similar tot he eye of a hurricane. Tornadoes like these may also have smaller subvorticies or suction vorticies circling inside of them, which can produce more severe damage. These are called multiple vortex tornadoes.
Most tornadoes descend from a lowering of the cloud base called a wall cloud. Although this is not a part of the tornado itself it plays a role in tornado formation.
The main parts of a tornado include the funnel cloud, which is the rotating column of air extending from the cloud to the ground, and the debris cloud, made up of objects carried by the tornado's strong winds. Tornadoes can also have an inflow jet, which is a narrow current of air flowing into the tornado, and an outflow jet, which is the upward and outward flow of air at the top of the tornado.

What is the reach of the speed a tornado can go?
Tornado speeds can range from around 65 mph (105 km/h) to over 200 mph (322 km/h) or more. The speed can vary within a single tornado, with different parts rotating at different speeds.
What are the parts on a tornado?
A tornado typically consists of a rotating column of air called a vortex, which is surrounded by a condensation funnel made up of water droplets or debris. It also has an updraft at its center, where warm air rises rapidly, and a downdraft around the periphery where colder air descends.
What explains the effect a tornado has on a normal wind speed and direction?
A tornado will produce a very rapid increase in wind speed and similarly rapid changes in wind direction. This is because the wind in a tornado spins around a central axis at high speed. Wind direction shifts as different parts of the tornado pass over.
When does a tornado actually become a tornado?
A tornado is officially confirmed when a rotating column of air reaches the ground and makes contact with the surface. This contact creates the characteristic funnel cloud shape that is associated with tornadoes.
What is the pressure of a tornado?
The pressure in a tornado typically decreases rapidly as the tornado forms, leading to low pressure at the center. The lowest pressures can be as low as 300 mb (millibars) inside a strong tornado.
