Definition

1. Noun:
   • An artificial cloud created by an aircraft: A visible line of cloud-like streaks in the sky, caused either by the condensation of water vapor due to the reduction in air pressure above an aircraft's wings or by water vapor in the engine exhaust.

Usage

• The term "condensation trail" is a technical and formal term used primarily in meteorology and aviation contexts. It describes a specific, visible atmospheric phenomenon.
• It is often used in scientific writing, technical reports, and formal discussions about aviation's environmental impact.

Examples

• Noun:
  • The clear blue sky was marked by the long, white condensation trail from the jet.
  • Scientists study condensation trails to understand their effect on climate and cloud formation.

Advanced Usage

• "Persistent condensation trail": A condensation trail that remains visible in the sky for an extended period, often spreading to form cirrus-like clouds.
  • The forecast indicated conditions were right for the formation of persistent condensation trails.

Variants and Related Words

• Contrail (n): A common shortened form of "condensation trail." This is the most frequently used term in both technical and general contexts.
  • The sky was crisscrossed with contrails from the busy air corridor.

Synonyms

• Vapor trail (n): Another common synonym for "condensation trail," emphasizing the visible trail of water vapor.
  • The old propeller plane left a faint vapor trail in its wake.

Different Meanings

• The term "condensation trail" is highly specific and does not have other common meanings outside of this aviation and meteorological context. It should not be confused with general "condensation," which is the process of a gas turning into a liquid.

Related Phrases

• "To leave a condensation trail": The action of an aircraft producing this visible streak.
  • High-altitude aircraft are more likely to leave a condensation trail.

Noun

1. an artificial cloud created by an aircraft; caused either by condensation due to the reduction in air pressure above the wing surface or by water vapor in the engine exhaust
