Warm air rises, then cools and falls back to Earth. This process is called convection, and results in huge movements of air. Winds in this layer are mostly vertical. The air is very thin. Jet planes often fly in the lower Stratosphere to avoid bad weather in the Troposphere.

The oxygen molecule we need to breathe contains two oxygen atoms. The increase is caused by the absorption of UV radiation by the oxygen and ozone.
