WebContrails are formed from extremely cold air mixing with hot exhaust gasses. Contrail formation is most likely at altitudes at or above 35,000 … Webdiagnosing and predicting persistent contrail formation from numerical weather output. In the contrail tracking system, the satellite, flight track, and meteorological data were used together to determine the location and altitude of contrail formation, and the temperature and humidity conditions under which the contrails formed. The flight track

Web1 jan. 2012 · Figure 33.1 shows a faint iridescent sheet of ice crystals between the thick exhaust contrails. These are formed by aerodynamic effects, namely the strong cooling of the air when it passes over the wings. When air is accelerated while flowing over the wing its pressure and temperature drop and substantial supersaturation can occur that allows … WebContrails form when saturation with respect to water is temporarily reached in the plume behind an aircraft, and they persist in ice supersaturated air masses. The ambient temperature necessary for contrail formation can be predicted accurately. Contrail particles consist of ice crystals. Web29 mrt. 2011 · Contrails formed by aircraft can evolve into cirrus clouds indistinguishable from those formed naturally.
