A tornado (often referred to as a twister or, erroneously, a cyclone) is a violent, dangerous, rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Tornadoes come in many shapes and sizes, but are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust.
Nope... you're describing a tornado.

When the vapor touches the cold surface of the funnel, it undergoes condensation and changes from a gas to a liquid. This process releases heat and energy, causing the vapor to lose its thermal energy and transition into a liquid state.
When a funnel cloud touches the ground it becomes a tornado.
A tornado that touches the ground is simply a tornado. Before it touches down it is called a funnel cloud.
A funnel-shaped cloud is called a tornado. It is a violent rotating column of air that extends from a thunderstorm to the ground. Tornadoes are capable of causing significant damage and are associated with severe weather events.
A funnel cloud that touches the ground is a tornado.
A funnel cloud that touches the ground becomes a tornado. It is the result of a rotating column of air extending from a thunderstorm cloud to the ground. Tornadoes can cause significant damage and pose a serious threat to life and property.
When a tornado has not touched the ground yet, it is called a funnel cloud. A funnel cloud is a rotating cone-shaped cloud descending from the base of a thunderstorm but not reaching the ground. Once it touches the ground, it is classified as a tornado.

The process of a tornado forming is called tornado genesis. Usually a tornado is a funnel cloud before it touches down.
