Efficiency. A jet engine works best in thin air.
Stratosphere
The jet stream is located in the tropopause, which is the boundary between the troposphere and the stratosphere. It typically flows at high altitudes, around 10-15 kilometers above the Earth's surface.
As a jet ascends from Earth's surface into the stratosphere, the exterior temperature typically decreases initially due to the troposphere's temperature gradient, which generally cools with altitude. However, once the jet reaches the stratosphere, the temperature begins to stabilize and can even increase slightly with altitude due to the absorption of ultraviolet radiation by the ozone layer. This transition leads to a more stable temperature profile in the stratosphere compared to the cooler, turbulent conditions of the troposphere.
Jet planes fly in the stratosphere, which is the second layer of Earth's atmosphere. This layer provides a stable environment for jet propulsion and allows for efficient flying at high altitudes.
The fact that jet airplanes' contrails form cirrus clouds suggests that they fly at altitudes where the temperature and humidity are conducive to contrail formation, typically above 20,000 feet. This indicates that jet airplanes generally fly at high altitudes, where the air is colder and less dense, allowing contrails to persist and spread out into cirrus clouds.

the stratosphere
In the stratosphere, you can find the ozone layer, which helps protect Earth from the sun's harmful ultraviolet radiation. Additionally, the stratosphere is where airplanes fly and where some weather phenomena, like jet streams, occur.
No. The jet stream is in the upper troposphere and lower stratosphere.
Yes, the stratosphere is suitable for airplanes to fly. In fact, commercial jet aircraft typically cruise in the lower stratosphere because of its stable conditions and lack of turbulence. The stratosphere also allows for efficient fuel consumption and higher speeds due to reduced air resistance at higher altitudes.

the stratosphere.
Yes.
The stratosphere is the ideal layer of the atmosphere for flying airplanes due to its stability and smooth air currents, which minimize turbulence and provide more efficient fuel consumption. In the stratosphere, the jet stream can also help increase the speed of the aircraft.
