noun a visible trail left in the sky by an aircraft and consisting of a line of condensed water or ice particles created by the aircraft's engines
Contrails can contribute to climate change by trapping heat in the atmosphere.
Contrails are the long, thin clouds that form behind aircraft when water vapor in the exhaust condenses and freezes.
Pilots use contrails as a visual indication of atmospheric conditions, such as humidity and temperature.
Contrails play a role in studying atmospheric dynamics and cloud formation.
Engineers study contrails to improve aircraft efficiency and reduce environmental impact.
In the context of a writer, 'contrail' may be used to describe the visible trail left in the sky by an aircraft as it passes through the air, often used as a metaphor for a fleeting or temporary mark or impression.
Meteorologists may use 'contrail' to refer to the line-shaped clouds produced by aircraft engine exhaust or that are caused by changes in air pressure or temperature, which can provide valuable information about atmospheric conditions.
Pilots may use 'contrail' to discuss the formation of condensation trails behind their aircraft at high altitudes, which can affect visibility and air traffic control.
