Vapor Trails Explained: Here Are Some Stunning Images
These photos of plumes of air billowing from the back ends of aircraft may seem like a cause for concern, especially when they are a bright red in color. But the images actually show spinning vapor trails created by cold air circulating around the wing. Moreover, as the number of planes in the sky increases more and more, these vapors have become a spectacular sight, resulting in some of the incredible pictures of plane trails.
Here are some explanations how these vapor trails are created:
Speed of sound: The cloud cone is created by an aircraft at high speed, and can often be seen when planes break the sound barrier.
Parting the sky: As plane fly through clouds, the air pressure splits them. When an aircraft passes through a cloud, water vapor and ice from the clouds are sucked into the vortices, adding to the effect.
Bursting through: When a plane makes a hole in a cloud, the sunlight shining through can create some amazing effects. The air pressure created around the plane can also cut through a cloud, parting the vapors and leaving spectacular patterns behind as the clouds gather around the vortices.
Dusk: The vortices that are formed by the plane can come off in unstable forms, shown by the light hitting the trails at sunset.
