The hole in the ozone layer forms every year during the austral spring, between August and October, and reaches its maximum between mid-September and mid-October. This year, after a fairly normal initial condition, it increased dramatically last week and is now 75% larger than the measurements taken at this same time of year since 1979.

“We expect it to close by 2050” – “Although similar to that of 2020, this year the ozone hole has turned into one of the longest ever recorded”, observes Vincent-Henri Peuch, director of the Copernicus Atmosphere Monitoring Service. For Antje Inness, of the European Center for Medium Range Meteorological Forecasts, “the monitoring of the ozone hole at the South Pole must be interpreted with caution, as size, duration and concentrations are influenced by local winds. However, we expect it to close. by 2050 “.

With the end of the spring season in the Southern Hemisphere, as temperatures in the upper stratosphere begin to rise, ozone depletion slows. The polar vortex weakens and eventually breaks down, bringing ozone levels back to normal by December.
