Cold air is not a necessary ingredient in forming tornadoes, but it often plays a role. One of the most common places to find a tornado is ahead of a cold front. A cold front is a boundary where a cool air mass pushes into and replaces a warmer one. Since warm air is less dense than cold air, the warm air mass gets force upwards. If there is enough instability in this air mass, the lift can trigger thunderstorms ahead of the front. Given the right conditions these thunderstorms can start rotating and produce tornadoes.

How does a funnel in a tornado form?
The tornado pulls in moist air from the rainy portion of the parent storm. When the air is suddenly decompressed inside the tornado it cools and the moisture condenses, forming a cloud.
What causes a tornado to lose its strength?
A tornado typically loses strength when cold or dry air undercuts the thunderstorm updraft that drives it. This cuts off the supply of air that power the storm and, in turn, the tornado.
Why do many tornadoes appear transparent?
Air is transparent. Therefore the fundamental forming medium of a tornado will be invisible (transparent) it is only when the tornado incorporates water droplets (form the forming cloud) or debris form the ground that it becomes visible / opaque.
What is a tornado made of air?
A tornado made of air is a tornado. Part of the definition of a tornado is "a violently rotating column of air."
What two air masses would most likely form a tornado when they meet?
A cold air mas moving into a warm air mass will create a cold front. It is along a cold front that the severe thunderstorms that can produce tornadoes most often form.
Do a tornado form when a funnel of cold air quickly rises from the earth?
No. Tornadoes form in an environment where warm air rises quickly. Cold air will resist rising and will tend to prevent tornadoes from forming.
What is a tornado composed of?
A tornado is essentially a vortex of air. Usually the moisutre in the air in a tornado will condense into water droplets, forming a visible funnel cloud. Tornadoes will often lift soil into the air, forming a dust whirl. If a tornado hits trees or man-made structures it may pick up debris as well.
What is it called when cold air meets warm air?
tornado

Are tornado winds cold?
It all depends on where and when the tornado occurs, and what the actual temperature is in the area. Most tornadoes form ahead of a boundary where cold air plows into warm air called a cold front. Generally the warmer, and moister the air mass the better chance there is of a tornado forming. Because tornadoes generally form in the rear portion of a thunderstorm the air may be somewhat cooler than in the rest of the warm air mass. Inside the tornado itself there will be another temperature drop due to decompression. So a tornado is generally cooler than its surroundings, but is will still tend to be relatively warm. That said, tornadoes can occasionally form in fairly cool air, in which case the winds would definitely cold, especially with wind shill factored in.
Is the warm air mass forming a tornado a tropical air mass?
Yes. The warm air mass that often plays a role in tornado formation is called a maritime tropical air mass.
What does cold and hot air make?
it makes a tornado
When warm air is lifted up over the cold air it is called?
tornado
Does a tornado from bottom to top?
Air moves up in a tornado, but in the process of forming, most tornadoes start as a vortex high up in the clouds.
What does Hot and cold air moving make?
it makes a tornado
What does Hot and cold air moving making what?
it makes a tornado
Does the cold air go up in tornadoes?
Air does go up in a tornado and it is cooler than surrounding air due to decompression. However, it is generally fed by warm air. If too much cold air gets into the circulation, the tornado will dissipate.
