What is the name of the white trails that jets leave behind?

The white trails left behind jets are known as contrails.


What is an airplane smoke trail called?

Contrails or condensation trails


What does the cloud name contrails mean?

Contrails is a shortening of condensation trails.


What kind of clouds are contrail?

Contrails are clouds that appear behind aircrafts. Contrails are long, thin, man-made clouds that are essentially vapor trails. These vapor trails are created by a change in water vapor or changes in air pressure.


What are the trails planes leave behind?

Contrails are just condensation from the hot gases leaving the engine of the plane interacting with the cold air in the upper atmosphere.


What is the name of the fume like seen in the air when a jet flies?

Contrails or vapour trails.


What is white smoke frrom the flight like a line behind the flight?

It's called Contrails (condensation trails), and it's humidity condensing (gases that turn to fluids) as hot air from engine exhaust, meet the freezing cold air at altitudes of 30000 feet or more.


What is a clue left behind by an animal called?

"Scat" or feces is left behind on trails.


What are contrails and how do they form?

Contrails are clouds that form behind airplanes when hot exhaust gases containing water vapor mix with cold air at high altitudes. The water vapor in the exhaust condenses into tiny ice crystals, creating a visible trail. Contrails can persist for a while depending on atmospheric conditions.


What do you call the trail behind high-flying jets?

These are called "contrails" (short for "condensation trails") and are ice crystals formed from the water released by a jet engine. When jet fuel burns, it creates gases including carbon dioxide, but also substantial water vapor. At high altitudes, the temperature is much lower than on the ground, and water condenses and freezes. Depending on the altitude, wind, and the humidity of the air, contrails can persist for a few seconds or for many hours. When many contrails combine to form long-lasting clouds, they can affect the weather like any other cloud, except that they are higher in the atmosphere.


What is white residue on evaporation of jet fuel?

If you are referring to the expansive wisps of what appears to be long cirrus clouds that trail behind jet engines in flight, then you are talking about condensation trails, or contrails. These are caused by the water vapour, a by-product of exhaust, rapidly saturating the surrounding air. At high altitudes, these tiny water droplets condense and remain suspended as ice crystals. Contrails can also be caused by the wingtip vortices of heavy aircraft at low speeds travelling through a high relative humidity environment. Although these contrails usually occur much closer to the ground, and do not remain suspended for an extended period of time, as do the contrails caused by exhaust.


What is the white smoke made of that is behind planes?

The white smoke behind planes is primarily composed of water vapor formed by the engine exhaust gases cooling and condensing in the cold air at high altitudes. This phenomenon is known as contrails.
