FAQ
Frequently Asked Questions
A dissipation trail is a specific type of contrail. All dissipation trails are contrails, but not all contrails are dissipation trails. A dissipation trail is one that forms and then rapidly vanishes.
It is highly unlikely to be understood in general conversation. The common term is 'contrail' or 'vapour trail'. Use 'dissipation trail' only when discussing the specific meteorological distinction with a knowledgeable audience.
It forms when hot, humid exhaust from aircraft engines mixes with cold, low-pressure air. If the surrounding air is very dry (low relative humidity), the ice crystals that make up the trail sublimate (turn directly to vapour) almost immediately, causing the trail to dissipate.
The opposite is a 'persistent contrail' or 'spreading contrail', which remains in the sky for a long time and can even spread out to form cirrus clouds, often due to higher humidity in the atmosphere.
A visible line or trail left in the sky by an aircraft, typically a jet, resulting from the condensation and subsequent evaporation of water vapor in the engine exhaust.
