contrails are "clouds" formed by the hot, humid air from plane/jet engines which mixes with water vapor high in the sky, then turning into ice crystals which then create contr…ails. (MORE)
since contrails could form into cirrus clouds, and cirrus clouds form a warm front, the weather should change from being warm in the afternoon and cooler at night.
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.

Jet contrails are water condensation resulting from the rapid compression and decompression of the air around the wing as the airplane moves through the atmosphere. The atm…ospheric conditions have to be just right for contrails to occur, and that is why you sometimes see contrails seem to wink off and on, as the airplane passes through drier air the contrails will stop.

Contrails can be considered to be cirrus clouds, since they are structurally the same. These high clouds have a strong tendency to allow shortwave solar radiation to pass thro…ugh but block longwave (heat) coming up from the earth. So basically, they act as a greenhouse gas, as opposed to lower clouds. If you get a lot of contrails in one area, it can have a minor warming effect on the surface. (MORE)
Contrails are the white, cloudlike trails left behind jets flying in the sky. They form when water vapor, a byproduct of the combustion taking place in the jet engines, conden…ses into water droplets (or ice crystals, if the temperature is low enough) after it has cooled down from the colder temperature high in the sky. This is similar to how clouds form. (MORE)
Contrails are long, artificial clouds that are man-made, sometimes trailing an aircraft. They are made most commonly by the water vapor in the exhaust of the engines of aircr…afts. However, they can also be made from changes in the air pressure. (MORE)
