Commercial jet aircraft typically cruise in the lower stratosphere precisely because the stable air pressure and lack of weather turbulence provide a smooth and efficient ride. 1 The Ozone Connection and Solar Influence The unique pressure curve of the stratosphere is inextricably linked to the ozone layer.
Stratosphere Air Pressure Decrease Pattern and Its Drivers
In the lower stratosphere, temperatures remain relatively stable or even increase due to the absorption of ultraviolet (UV) radiation by ozone. Numerical Values and Atmospheric Data The actual numbers illustrating air pressure in the stratosphere reveal the dramatic thinning of air.
Ozone molecules absorb high-energy UV photons, converting that energy into heat. This heating process warms the stratosphere, creating the temperature inversion that stabilizes the layer.
Stratosphere Air Pressure Decrease Pattern and Its Drivers
Consequently, the air pressure behavior is not just a result of gravity but is actively modulated by this solar-driven chemical process. Unlike the rapid pressure drop in the troposphere, the stratosphere exhibits a more gradual flattening of pressure as altitude increases.
