How is ozone layer formed in stratosphere

Web17 dec. 2024 · About 90% of the ozone on Earth is in the stratosphere. And since pressure decreases as you go up in altitude, most of that ozone is concentrated in the lower stratosphere. This is what we think of as the ozone layer. Ozone, by the way, is a molecule consisting of three oxygen atoms. WebThe ozone hole is formed each year in the Southern Hemisphere spring (September-November) when there is a sharp decline (currently up to 60%) in the total ozone over most of Antarctica. During the cold dark Antarctic winter, stratospheric ice clouds (PSCs, polar stratospheric clouds) form when temperatures drop below -78C.
