Atmospheric Ozone Hole Over Arctic Region

Elizabeth Borneman

A combination of atmospheric factors have led to the creation of the lowest levels of ozone in a decade over the Arctic.

the jet stream shifted from about 49° S to 51° S between 1980 and 2000 — the years when the stratospheric ozone layer over Antarctica was becoming depleted. The trend alters after 2000, when the ozone layer began to recover as a result of the Montreal Protocol, which banned ozone-depleting substances. Image: Banerjee et al., 2020.
