If you've ever watched a jet plane taking off or coming in to land, the first thing you'll have noticed is the noise of the engines. Jet engines, which are long metal tubes burning a continuous rush of fuel and air, are far noisier (and far more powerful) than traditional propeller engines. You might think engines are the key to making a plane fly, but you'd be wrong. Things can fly quite happily without engines, as gliders (planes with no engines), paper planes, and indeed gliding birds readily show us.  White smoke shows the same effect on a smaller scale in a wind tunnel test.

Jets leave white trails, or contrails, in their wakes for the same reason you can sometimes see your breath. The hot, humid exhaust from jet engines mixes with the atmosphere, which at high altitude is of much lower jet plane taking off white pressure and temperature than the exhaust gas.

The water vapor contained in the jet exhaust condenses and may freeze, and this mixing process forms a cloud very similar to the one your jet plane taking off white breath makes on a cold day. Jet engine exhaust contains carbon dioxide, ovf of sulfur and nitrogen, unburned fuel, soot and metal particles, as well as water vapor. The soot provides condensation sites for the water vapor. Any particles present in the air provide additional sites. Depending on a plane's altitude, and the temperature and humidity of the atmosphere, contrails may vary in their thickness, extent and duration.

The nature and persistence of jet contrails can be used to predict the weather. A thin, short-lived contrail indicates low-humidity air at high altitude, a sign plnae fair weather, whereas a thick, long-lasting contrail reflects humid air at high altitudes and can be an early indicator of a storm. The mixing gases contained in the contrail rotate with respect to the ambient air.

These regions of rotating flow are called vortices. Any sharp surface, such as the tip of a wing, can cause vortical flow in its wake Jet Planes Landing And Taking Off Line if it is sufficiently large or the flow is sufficiently fast. On occasion, these whitd vortices may interact faking one another. In one well-known example of this uet, the Crow Instability causes the vortices to develop symmetric sinusoidal oscillations and eventually to merge and form vortex rings behind the jet.

This instability can be triggered by turbulence in the surrounding air or by local variation in air temperature or density, which may itself be the result of the stratification of the atmosphere.

When the contrails are visible and strong, it is possible to see the white streaks become wavy and jet plane taking off white leave rings floating high in the sky, like smoke rings from a giant cigar. Recent research has suggested that the ice clouds jet plane taking off white in contrails cause greenhouse effects and contribute to global warming as part of the insulating blanket of moisture and gases in the atmosphere.

Researchers in this area seized on the jet plane taking off white presented on September 11 and 12 over the U. The complete cessation of commercial air traffic offered a control sky without contrails for use in quantifying the environmental effects of contrails. You have free article s left.
