A tornado produces a funnel-shaped cloud.
Not much unless it touches down, in which case it is called a tornado.
It is a cirrus cloud.
Cumulus
No, it can not happen. You will always need a cloud to form a tornado. The kind of cloud that a tornado uses is a cumulonimbus cloud.
Status
Signs of a potential tornado include rotation in the clouds, a persistent lowering of the cloud base, and a hole opening up in the clouds near the back of a storm (these are all potential precursors). Other signs include a funnel or con shaped extension of the cloud base, and swirling debris on the ground, indicating that a tornado or funnel cloud has formed.
the tornado kind
it becomes a tornado
Tornadoes form during thunderstorms, usually an especially severe kind called a supercell. The storms take the form of anvil-shaped cumulonimbus clouds. The sides of these storms sometimes look like stacked plates. However, if you are observing a tornado, you will be under the storm, and will not be able to observe this structure. The area of intrest will revolve around the wall cloud, which is a rotating mass of clouds that hangs below the main cloud base. The tornado itself will produce a funnel, which may be cone, needle, rope, or column shaped. However, not all tornadoes come with a wall cloud or condensation funnel, and these features, even if present, may be obscured by rain.
Neither. A funnel cloud that touches the ground is a tornado. A thunderhead is the sort of cloud that develops into a thunderstorm, and a supercell is the kind of thunderstorm most likely to produce a tornado.
funnel
A violent windstorm that often takes the shape of a funnel is called a tornado.
cumulonimbus clouds

No. Tornadoes themselves are a kind of violently rotating windstorm. The cloud of a tornado, known as the funnel, is found in most tornadoes but not all.
nimbus in latin is a rain cloud, a cloud, a cloudburst, a shower Nimbus Latin, related to Nebula, nephele, properly vapour, cloud), in art and archeology signifies a shining light implying great dignity. Closely related are the halo, glory, and aureole. EDIT: Nimbus: Literally it is a violentl- pouring rain-storm. The meaning was then transferred to a could that produced such a storm: a dark raincould. From that meaning there stemmed many more: any dark cloud, anything that was shaped like a cloud, a kind headband worn by women (maybe shaped like a cloud), and a vessel for sprinkling perfume (so it poured out perfume like a cloud poured out rain).
It depends. Common whirlwinds such as dust devils and steam devils are not associated with any sort of cloud formation. Tornadoes involve multiple cloud types. In a typical case, a funnel cloud emeges from a wall cloud, which is attatched to a cumulonimbus cloud. Waterspouts can from from cumulonimbu or cumulus congestus clouds.
