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.
