How is a contrail formed
Web25 mrt. 2024 · Aircraft engines produce condensation trails, or contrails, as hot, humid exhaust mixes with the atmosphere at altitudes of 8 – 13 km. Specifically, water vapor from the jet exhaust condenses and may freeze at high altitudes, where there is a lower vapor pressure and temperature than the exhaust. WebBecause the plane's contrail is not yet visible (contrails usually form above 26,000 feet, depending on the temperature and other factors) the distrail looks like a tunnel through the cloud if the cloud is very thin. [19] Distrails are created by the elevated temperature of the exhaust gases absorbing the moisture from the cloud.
