Air that enters a tornado spirals upward rapidly into the parent thunderstorm, becoming part of the main updraft. Some of this air may reach the upper troposphere where it will eventually be carried away by upper level winds. Some air may become part of the storm's downdraft and be dragged back to earth by rain.

A tornado's funnel cloud results when?
A tornado's funnel cloud forms when warm, moist air rises rapidly and creates a rotating column of air. This spinning motion causes the air to condense into a funnel shape, which is visible as the iconic tornado funnel cloud.
Is a funnel cloud a tornado?
Not technically. It is the beginning of a tornado, but they are categorized differently. It is not considered a tornado until it reaches the ground with damaging winds.
How does a funnel in a tornado form?
A funnel cloud forms when a rotating column of air descends from a thunderstorm cloud but doesn't touch the ground. When the funnel cloud touches the ground, it becomes a tornado. The rotating air within the tornado causes it to appear as a funnel-shaped cloud.
Is a tornado a funnel of water?
No. While the funnel is made visible by condensation, it is mostly air.
Which of these is a narrow funnel of air extending down from a cumulonimbus cloud?
A tornado is a narrow funnel of air that extends down from a cumulonimbus cloud, usually associated with severe thunderstorms.
How does the funnel occur in a tornado?
A tornado pulls in air that has become moist due mostly to rainfall. The rapid pressure drop inside the tornado cools the air, causing the moisture to condense and form a funnel shaped cloud.
True or false a tornado is a funnel cloud that has touched the ground?
True. A tornado is a rapidly rotating column of air that extends from a thunderstorm to the ground, and when it touches the ground it is then classified as a tornado. The funnel cloud is the visible condensation funnel attached to the rotating column of air but becomes a tornado once it touches the ground.
What do the air in a tornado do when the funnel touch the ground?
When a tornado funnel touches the ground, the air near the surface rushes inward at high speeds and begins to rotate rapidly. This rotation causes the funnel cloud to extend downward, allowing the tornado to make contact with the ground and causing destruction in its path.
What is going on in the funnel of a tornado?
In the funnel of a tornado, intense updrafts draw air in and cause it to rotate rapidly. The rotating air may contain debris and dust, giving the funnel its characteristic appearance. Wind speeds can be extremely high and cause significant damage as the tornado moves across the ground.
When a funnel of a tornado touches the ground what happens?
In this case it can be confirmed that the tornado has touched down. The funnel of a tornado does not have to touch down for the tornado to do so, and the vortex actually reaches the ground before the funnel does. The circulation reaching the ground is a more significant event. When the vortex is aloft its updraft can draw in air from directly below. This is no longer possible when the circulation reaches the ground. Since air can no longer be drawn in from below the pressure inside the vortex drops, causing the wind in it to intensify.
Air pressure inside the funnel cloud of a tornado is extremely?
low
The beginnings of a tornado are known as a funnel cloud?
Yes. A tornado is often visible as a funnel cloud as it develops.
