First-ever Arctic ozone hole: How it formed, what it may mean

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. WebThe process of stratospheric ozone formation starts with ozone (O 3 ), which is made by ultraviolet sunlight in the stratosphere (but not the troposphere, as we shall see). The two reactions are: This equation is … Web4 jan. 2024 · The study was published Jan. 4 in the journal Geophysical Research Letters.

Web5 mei 2010 · The hole in the ozone layer was perhaps the worst example of mankind’s impact on the planet, but a world-wide campaign against ozone-depleting chemicals has helped repair most of the damage. WebThe type of ice cloud chemistry that creates the ozone hole occurs primarily in the polar regions. But it has now been found that given a sufficient amount of CFCs, a similar thing can happen anywhere. In fact if CFCs had not been regulated, NASA simulations show that we would have had more than 50 percent ozone depletion here.
