Is there wind in the stratosphere?

The content of water vapor and dust is very small. Due to the low content of water vapor and dust, the weather phenomena in the troposphere rarely appear in this layer, and only some scattered shellfish clouds occasionally appear at the bottom. The stratosphere is sunny and the atmosphere is transparent.

The airflow in this layer is quite stable and mainly horizontal, hence the name stratosphere. Modern civil aircraft can fly in the stratosphere.

Extended data

Communication application:

In stratospheric space, the quasi-stationary long-endurance airship is used as the high-altitude information platform, and the stratosphere is generated by an integrated information system composed of ground control equipment, information interface equipment and various wireless user terminals.

Compared with the communication satellite, the round-trip delay of the communication system is shorter and the free space attenuation is smaller, which is beneficial to the miniaturization, broadband and symmetrical duplex wireless access of the communication terminal. Compared with the terrestrial cellular system, the stratospheric platform has the advantages of long working distance, large coverage area and small channel fading, so it can significantly reduce the transmission power.

It not only greatly reduces the construction cost of the ground information infrastructure, but also reduces the radiation pollution around the base station. The contribution to mankind is considerable.
