What Type of Clouds Make Tornadoes? - Sciencing
2018年7月20日 — During a thunderstorm, varied winds cause air rotation. Updrafts and downdrafts tip this upright into a mesocyclone, which pulls warm, moist air into a cumulonimbus, producing a wall cloud from which funnel clouds emerge. If a funnel cloud touches the ground, it …
Cumulonimbus cloud - Wikipedia
When causing thunderstorms, these clouds may be called thunderheads. Cumulonimbus can form alone, in clusters, or along squall lines. These clouds are capable of producing lightning and other dangerous severe weather, such as tornadoes, hazardous winds, and large hailstones.
Storm Clouds That Spell Severe Weather - ThoughtCo
2019年7月3日 — Produced when a rotating column of air condenses, funnel clouds are the visible part of tornadoes that extend downward from the parent thunderstorm cloud. But remember, not until the funnel reaches the ground or "touches down" is it called a tornado.
Tornado - Wikipedia
A tornado is a violently 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.

A wall cloud is an isolated cloud lowering attached to the rain-free base of the thunderstorm. The wall cloud is usually to the rear of the visible precipitation area. A wall cloud that may produce a tornado can exist for 10–20 minutes before a tornado appears, but not always.
Wall cloud - Wikipedia
A wall cloud (murus [1] or pedestal cloud) is a large, localized, persistent, and often abrupt lowering of cloud that develops beneath the surrounding base of a cumulonimbus cloud and from which tornadoes sometimes form. [2]
What Causes Tornadoes? | NOAA SciJinks – All About Weather
2024年9月11日 — The Short Answer: A tornado forms from a large thunderstorm. Inside thunderclouds, warm, humid air rises, while cool air falls--along with rain or hail. These conditions can cause spinning air currents inside the cloud. Although the spinning currents start out horizontal, they can turn vertical and drop down from the cloud--becoming a tornado.

2024年8月4日 — The looming cone-shaped cloud was rapidly rising into the sky, appearing at first glance to be an ominous tornado just over the trees. Thankfully, it was just the thunderstorm’s updraft moving...

2024年10月10日 — A tornado is a relatively small-diameter column of violently rotating air developed within a convective cloud that is in contact with the ground, usually in association with thunderstorms during spring and summer.
What Do Tornado Clouds Look Like
Tornado clouds, also known as supercell thunderstorms, are the breeding grounds for tornadoes. These massive storm systems are characterized by their rotating updrafts and mesocyclones, which are large-scale cyclonic circulations within the storm.
