Contrails are clouds that appear behind aircrafts. Contrails are long, thin, man-made clouds that are essentially vapor trails. These vapor trails are created by a change in water vapor or changes in air pressure.
it bring the rain
Both are mainly composed of droplets of condensed water.
The jetliner's engine/power keeps it on the desired direction of the flight. That engine/power is designed to be stronger than the winds (most of the time :) and thus the jetliner will look unaffected by them. The contrail on the other hand, once released, is free in the air without any inner force to give it a direction. Therefore the contrail will follow the wind's direction as do the clouds in its vicinity.
Contrail clouds can form at various altitudes depending on atmospheric conditions, but they typically occur between 25,000 and 40,000 feet above sea level. The exact height can vary based on factors such as temperature, humidity, and aircraft altitude.
Contrails are formed from the moisture in the exhaust of an airplane. The moisture condenses or crystallizes to form a visible cloud.
Patrick Minnis has written: 'Surface-based observations of contrail occurrence over the U.S' 'Surface-based observations of contrail occurrence over the U.S., April 1993-April 1994' -- subject(s): Contrails, Diurnal variations, Cirrus clouds
Misspelled it: It's contrail clouds. They're in family A, high altitude clouds. Contrails are made from either airplane exhaust or wingtip vortexes. Wingtip vortexes are essentially a drop in air pressure during flight, which causes a temperature change, which causes mositure to condense. That all leads to contrails. Airplane exhaust simply condenses to form clouds. Contrail clouds last long after the plane has left.
The heat of the compressed air from the aircraft engine via the engine's exhaust heats the water vapor in the air (air is cooler in the atmosphere) making condensation in the form of a cloud, for the cloud info type in: How do clouds form? If you just need info on the contrails just add on how clouds form onto the contrail. Hope that helps.
