Clouds airplanes make
Have you ever looked up and seen a jet airplane high in the sky?
Sometimes you will see what looks like a trail of white smoke stretched
out behind the plane. This trail is a cloud made by the jet.
The air high in the sky is cold and frosty. Hot gas, left over from
burned fuel, comes out of the jet’s engines. There is a lot of water
vapor in this hot gas. When the water vapor hits the cold ah’, it
instantly condenses into tiny water droplets or ice crystals. So the jet
leaves a long, white cloud behind it.
These long clouds that a jet makes are called contrails, which is short
for “condensation trail.” Contrails are also called vapor trails.
Contrails sometimes cause rainstorms or snowstorms.
