What is a contrail?
Contrails are line-shaped clouds sometimes produced by aircraft engine exhaust, typically at aircraft cruise altitudes several miles above the Earth’s surface.
What does a contrails look like?
Contrails may appear on clear or partly cloudy days because of jet engine exhaust that contains water vapor. The water vapor condenses at high altitudes where a layer of air is cold and contains moisture. The condensation is visible from the ground, appearing to look like pencil thin lines of ‘cloud.
What is another name for a contrail?
condensation trail
Also called condensation trail, exhaust trail, vapor trail .
What are contrails used for?
The nature and persistence of jet contrails can be used to predict the weather. A thin, short-lived contrail indicates low-humidity air at high altitude, a sign of fair weather, whereas a thick, long-lasting contrail reflects humid air at high altitudes and can be an early indicator of a storm.
Why do Jets leave a trail?
Jets leave white trails, or contrails, in their wakes for the same reason you can sometimes see your breath. The hot, humid exhaust from jet engines mixes with the atmosphere, which at high altitude is of much lower vapor pressure and temperature than the exhaust gas.
Do turboprops produce contrails?
4 Answers. Contrails originate from condensation of vapor coming from internal combustion engines, regardless of being turboprop, turbojet/turbofan or cylinder engine. Vapor is a byproduct of the hydrocarbon (fuel) being combusted with the atmospheric oxygen.
What are contrails made of?
What are contrails made of? They are composed of ice particles that form in the exhaust of an aircraft when flying in a narrow range of altitudes in the upper atmosphere, several miles above the ground.
What is the difference between chemtrail and Contrail?
Contrails are condensation trails left in the sky when the water in aircraft engine exhaust condenses to form artificial clouds.
What are chemtrails, and are they dangerous?
The chemtrail conspiracy theory claims that some contrails are chemical, biological or otherwise toxic elements sprayed at high altitudes by government agencies — of some sort — for the purpose of — well, something not good. It’s high-altitude crop dusting for nefarious purposes,…
Do contrails damage the atmosphere?
Plane contrails have been found to increase heat in the upper atmosphere. The aviation industry has long been criticized for its large environmental footprint, particularly its climate-warming carbon emissions.
What chemtrails really are?
What Chemtrails Really Are. It involves the combination of chemtrails for creating an atmosphere that will support electromagnetic waves, ground-based, electromagnetic field oscillators called gyrotrons, and ionospheric heaters. Particulates make directed energy weapons work better. It has to do with “steady state” and particle density for plasma beam propagation.
