Contrails

Excess moisture from the engine of an airplane condenses quickly as it saturates the cold air high up in the troposphere. Tiny particles from the engine exhaust also help to form contrails fast as there is plenty of small condensation nuclei for the moisture to stick to.


Lentokoneen moottorin polttoprosessin aikaansaama ylimääräinen kosteus nopeasti tiivistyy kun se kyllästyttää kylmän ilman ylhäällä troposfäärissä. Pienet pakokaasun partikkelit auttaa myös muodostamaan tiivistysjuovia nopeasti kun ilmassa on runsaasti pieniä tiivistymisytimiä, joihin kosteus voi kiinnittyä.
