Polar scientists told what happens to the ozone hole in 2023

The ozone hole over Antarctica is formed very early, write researchers from the Center’s National Antarctic Science Center. These data are immediately confirmed by the measurements of Copernicus and Vernadskyi. Satellite data from the European Center for Medium-Range Weather Forecasts (Copernicus) suggest that the hole appears earlier this year. It usually begins to form in mid-August and grows in September. This is the period when the Antarctic spring is just beginning. Instead, now it appeared in August – when it is still winter in Antarctica.

According to Oleksandr Poludny, an ozonometer of the 28th UAE, since the beginning of this year’s observations (they started on July 22, when the sun began to rise high enough above the horizon), the general level of ozone was normal only one day – August 2. Then the indicator was 279 Dobson units, and the norm was 270-290. “On other days, the ozone level was reduced by about a quarter compared to the same period of previous years. And on August 7, it generally dropped to 201 Dobson units – this is already an indicator of the “ozone hole” (less than 220 units),” the polar explorers emphasize.

Then a large amount of water vapor entered the atmosphere. This is what formed ice clouds, which are ozone destroyers. The researchers also say that the early formation of the hole will have a negative impact on sea ice – its amount in the Antarctic is already at a record low. Low ozone levels will let more UV rays into the ocean, warming it and melting the ice. Earlier we wrote that in 2022 the hole did not increase significantly. We also talked about how exactly the ozone hole over Antarctica is studied and why this phenomenon is dangerous. Read also: Scientists discovered a huge ozone hole over the Arctic
