No. It is called a funnel cloud. However, tornadoes are produced by thunderstorms.

What are tornadoes called when they hit the ground?
A tornado that touches the ground is simply a tornado. Before it touches down it is called a funnel cloud.
Where does the force from a tornado come from?
The power of a tornado comes from the thunderstorm that produces it. A thunderstorm is powered by the energy that water vapor releases when it condenses. Differences in wind speed and direction wind altitude, a condition called wind shear, sets these storms rotating. This rotation can then tighten and intensify to form a tornado.
What makes a tornado a tornado?
The process of tornado formation starts when wind shear starts the updraft a a thunderstorm rotating, turning it into a supercell. If the right kind of down draft, called a rear-flank down draft occurs it can wrap around the rotating updraft, which is called a mesocyclone, and turn it into a more intense circulation: a tornado.
Where does the force from a tornado come from for kids?
The force of a tornado comes form a turning, rising mass of air in a thunderstorm called a mesocyclone. Sometimes a downward-moving wind called a downdraft can wrap around the mesocyclone and make it narrower, which causes it to spin faster.
How is an F5 tornado formed?
An F5 tornado forms in much the same way a any other tornado is. For general tornado formation first, a condition called wind shear, in which the speed or direction of the wind changes with altitude. If the shear is strong enough it can essentially tilt a thunderstorm, this separates the updraft and downdraft of the thunderstorm, preventing them from interfering with one another. This allows the storm to become stronger and last longer. Additionally, if the wind shear is strong enough it can start the air rolling in what is called horizontal vorticity. This horizontal vorticity can then be turned vertical by a thunderstorm's updraft. When this happens, the thunderstorm may start rotating. The rotation is especially strong in an updraft called a mesocyclone. If the storm intensifies rapidly enough, a relatively warm downdraft called a rear-flank downdraft or RFD can wrap around the bottom part of the mesocyclone. This can then tighten and intensify its rotation and bring it down to the ground to produce a tornado. An F5 tornado is simply the most extreme case of this where a supercell has an enormous amount of energy, is well organized, and wind shear is very strong.
What is a tornado before it is a tornado?
Before a tornado touches down it is called a funnel cloud, which looks like a tornado but does not reach the ground. A funnel cloud develops from the mesocyclone of a supercell thunderstorm. A supercell thunderstorm is characterized by the presence of a mesocyclone, which is a deep, continuously-rotating updraft.
What are tornadoes called when they hit the ground?
A tornado that touches the ground is simply a tornado. Before it touches down it is called a funnel cloud.
What are the beginnings of a tornado called?
The process of a tornado forming is called tornado genesis. Usually a tornado is a funnel cloud before it touches down.
A tornado is usually produced by?
A tornado is usually produced by a type of thunderstorm called a supercell.
What is a supercell tornado?
A supercell tornado is a tornado that forms from thunderstorm called a supercell. A supercell is a powerful thunderstorm that has a strong rotating updraft called a mesocyclone. Supercells are the strongest thunderstorms on earth. Most strong tornadoes are supercell tornadoes.
What is a rotating column of air that touches that ground?
A rotating column of air is known as a whirlwind. If it is violent and connects to both the ground and the cloud base of a thunderstorm, it is considered a tornado.
Is a tornado a type of storm?
A tornado comes from a type of storm called a rotating thunderstorm, but is not a storm, itself.
What is a tornado most likely to be produced from?
A tornado is most likely to be produce from a type of thunderstorm called a supercell.
A violent thunderstorm that can spawn a dangerous tornado?
Such storms are called supercells
What do you call a severe thunderstorm where a tornado begins?
In most cases the storm the produces a tornado is called a supercell, though in some cases tornadoes can develop in other types of thunderstorm.
What is a tornado and when may it form?
A tornado is a violently rotating columns of air in contact with the base of a thunderstorm and the ground. Tornadoes are usually produced by a type of strong thunderstorm called a supercell.
When the tip of the funnel cloud touches the ground it becomes a?
tornado clouds
