Have you ever seen white cloud-like trails in the sky? These trails of clouds that billow from an airplane or jet streaking across the sky can be mesmerizing and are called “Contrails”. Some people refer to them as “Chemtrails”
Here is what you need to know about Contrails.
“When a jet engine is spewing out hot, humid air into an atmosphere where the temperature is usually -40 C and has low vapor pressure, the result is condensation. The water vapor coming out of the engine quickly condenses into water droplets and then crystallizes into ice. The ice crystals are the clouds that form behind the engine. This is why the streaks are called contrails, short for condensation trails. Some elements of the exhaust gasses are not involved in contrail formation but do constitute air pollution.
Contrails exist for different lengths of time. Because of the differences in contrail life-spans, Contrails can be divided into 3 groups: short-lived, persistent, and persistent spreading.
Conspiracy theorists have nicknamed contrails as chemtrails under the suspicion that the government is taking advantage of this scientific phenomenon to secretly release other substances into the atmosphere.”
The concept of Chemtrails is still disputed and not yet accepted by many people. Contrails are usually spotted only during the winter months in Jaipur.
