There has to be circulation inside of a storm which if there is a tornado then it has that circulation. What makes it touchdown is when you have a strong updraft and downdraft which pushes that horizontal rotation into a vertical position which causes the funnel cloud to come in contact with the ground causing a tornado.
A funnel cloud becomes a tornado when it makes contact with the ground. Until that point, it is just a rotating column of air extending from a thunderstorm cloud. Once it touches down, it is classified as a tornado.
A strong tornado that forms a cloud of dust when it makes contact with the ground is called a "dust devil." Dust devils are relatively small whirlwinds that occur in arid or semi-arid regions and are driven by intense heating at the surface creating updrafts. Unlike tornadoes, dust devils are not associated with thunderstorms.
A funnel cloud that touches the ground is commonly known as a tornado.
A tornado that doesn't touch the ground isn't a tornado; it is a funnel cloud. However if the funnel is pulling debris off the ground or making some other type of contact with the ground it is a tornado.
There were numerous tornadoes in Oklahoma in 2013. The most well-known of these, the Moore EF5 tornado, lasted about 40 minbutes.
Yes. It is not officially counted as a tornado unless it touches the ground.
A tornado that touches the ground is simply a tornado. Before it touches down it is called a funnel cloud.
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.
Before a tornado hits the ground, a rotating column of air forms in the storm cloud known as a funnel cloud. This funnel cloud extends towards the ground, and once it makes contact, the tornado is then officially considered to have touched down.

"A tornado hit the barn." would be a sentence.
This is the birth of a tornado.
A tornado that does not touch the ground is a funnel cloud.

A tornado often appears dark were it is touching the ground be cause the powerful winds of the tornado lift dirt from the ground.
