The wind speed in a cumulonimbus cloud can vary widely, typically ranging from about 20 to 50 miles per hour. However, within severe thunderstorms, wind speeds can reach over 100 miles per hour, contributing to the intense turbulence and severe weather associated with these clouds.
When a funnel cloud touches the ground, it forms a tornado. Tornadoes are rapidly rotating columns of air that extend from the base of a cumulonimbus cloud to the ground. They can cause significant damage due to their strong winds and intense rotation.
The definition of a tornado is based more on the behavior of the wind than on its wind speed. A tornado is defined as a violently rotating column of air that connects to the ground and the cloud base. If a wind event does not meet these criteria, then it is not a tornado, regardless of the wind speed. On the Enhanced Fujita scale, tornadic winds are generally considered to start at 65 mph, but tornadoes have been rated with estimated winds as low as 55 mph. It is rare to obtain actual wind speed measurements from inside a tornado, so most of the time winds are estimated based on the damage caused.
A anemometer is used to measure wind speed.
A funnel cloud that makes strong wind noises is called a whistling funnel cloud. This phenomenon occurs when the wind rushes through the funnel cloud, creating a distinctive whistling sound due to the varying air pressures within the rotating column of air.
The proper name for a tornado is "tornado." It is a rapidly 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.

What causes a cumulonimbus cloud is the cold and warm fronts that colided.
There is no such thing as a cumulonimbus tornado. A cumulonimbus cloud is a ver large towering cloud. Most thunderstorms are cumulonimbus clouds, and some of the strongest of these storms are what produce tornadoes.
The entire thunderstorm is a cumulonimbus cloud.

A tornado has a funnel and is at the bottom of a cumulonimbus cloud. If its winds do not reach the ground, though it is just a funnel cloud.
