Vapour Trail
Stacked rocks near rivers can indicate a good fishing spot or a means to mark a trail.
Commonly known as a contrail (condensation trail), the white vaporous trail that is visible coming out of jet aircraft is a result of three concurrent events: 1. Hot jet exhaust cooling as it exits the jet engine. 2. Atmospheric moisture (humidity. 3. Particulate matter as residue from the burning of the jet fuel. As the jet exhaust cools, water molecules condense on the minute particles of carbon in the exhaust forming water droplets and visible vapor, which appears as the white trail behind the jet. The length of the trail generally is determined by the relative amount of atmospheric moisture (humidity) present in the plane's path. The more humidity, the longer the contrail, and conversely, the less humidity, the shorter the contrail. As time passes, the contrail disperses. Wind speed at that altitude can affect how long the contrail is visible. More wind will disperse the contrail more quickly.
the negative aspects of the heroin trail are what
The weatherman said that the latest jet stream would bring more cold air to the region on Friday. The jet flew over Wichita, leaving a trail of jet stream behind it.
Chalk can be used to write on any hard dark surface that is slightly abrasive (not polished smooth).
Smoke trail is the trail of smoke left behind by an aircraft as it flies in the sky.
The white trail you see behind an airplane in the sky is called a contrail. It's an artificial cloud made by the exhaust of jet aircraft or from the wingtips.
Ice crystals of frozen exhaust particles.
The white trail is called a contrail which is short for condensation trail. The fumes that are emitted from the engines of planes contain a large amount of water vapours. When the plane is at a high altitude, the temperature can be low enough to freeze the water vapour into tiny crystals which we see as a white trail. The trail disappears when the water evaporates.
the government is honeslty trying to posion us.. its called a chem trail.
The stream behind a jet is called a contrail. It is actually water vapor that condenses in the cold.
leaves behind a trail to himself...
A pheromone scent trail.
If you are asking about contrails it is dependent on the temperatures aloft. At colder temperatures the water vapor in the exhaust condenses and causes the contrails you see. The blue angels and other aerobatic-performance aircraft inject a special oil "smoke oil" into their exhaust in order to leave the smoke trail you see at airshows. But the "smoke trail" you see behind civilian and commercial aircraft isn't smoke at all, it is water vapor formed as described above.

jet plains have a white trail behind because of the moisture for some time. in higher layer of atmosphere where there is hot air to disturb it. this trail is suspeded for a long time
To trail behind somebody or something.
