Contrails (/ ˈ k ɒ n t r eɪ l z /; short for "condensation trails") or vapor trails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruising altitudes several kilometres/miles above the Earth's surface. They are composed primarily of water, in the form of ice crystals.

Aug 27, 2023 · Condensation trails, or contrails, are long, thin clouds that can form behind airplanes at cruising altitude. They are created by jet engines.

Jan 16, 2025 · Contrails are cloud-like formations made up of tiny water droplets or ice crystals. They form when the hot exhaust gases from an aircraft’s engine, which contains water vapor, meet the cooler, low-pressure air at high altitudes.

Sep 2, 2024 · Contrails, short for condensation trails, form when the hot, moist exhaust from an airplane’s engine meets the cold, low-pressure atmosphere at high altitudes.

Feb 8, 2024 · Contrails are produced when the atmosphere is cold enough to produce ice crystals in the exhaust. These trails of ice crystals are very visible and white, much like chemtrails. However, contrails dissipate within a few seconds or at most, one minute.

What Are Contrails, And How Are They Different From Clouds? In this engaging video, we will uncover the fascinating world of contrails and how they differ fr...

Mar 25, 2025 · contrail, streamer of cloud sometimes observed behind an airplane flying in clear cold humid air. A contrail forms when water vapour produced by the combustion of fuel in airplane engines condenses upon soot particles or sulfur aerosols in the plane’s exhaust.

The meaning of CONTRAIL is streaks of condensed water vapor created in the air by an airplane or rocket at high altitudes.

Contrail is short for “condensation trail.” A condensation trail is a streamer of cloud sometimes observed behind an airplane flying in clear, cold, humid air. Here’s what is known (and not known) about these man-made clouds.

What is a contrail and how does it form? To answer this question, lets first identify what a contrail is. A contrail is the condensation trail that is left behind by a passing jet plane.
