Largest Ozone hole over Arctic region healed
On March 2020, the scientists spotted the formation of an unusual hole in the ozone layer over the Arctic region. The hole spotted over the Arctic region was the largest hole identified till date. But, the European Union's Copernicus, an Earth observation programme declared that the largest hole on the ozone layer detected on March 2020, over the Arctic region (i.e) over the North pole is closed.
Copernicus of European Union made the announcement via Twitter post of April 23. They wrote, "The unprecedented 2020 northern hemisphere #OzoneHole has come to an end. The #PolarVortex split, allowing #ozone-rich air into the Arctic, closely matching last week's forecast from the #CopernicusAtmosphere Monitoring Service."
We know that, the humanity is facing a great threat called Corona Pandemic which has stepped into every nation as deadly virus and made people to stay inside their homes to avoid getting infected. Since, there is complete lockdown, we get to see videos of animals roaming in streets and roads, reports from weather channels saying that air pollution have been decreased gradually and all these with a tag "Nature is healing"! While Copernicus announced about the closing of ozone hole over Arctic region, Netizens were trying to frame this incident with the tag and the team of scientists have completely denied it. The agency also said that, the recovering of the hole isn't related to covid-19 lockdown but was caused by an unusually strong and long-lived polar vortex. FYI, this ozone layer hole was regarded to be the largest formed over the Arctic ever since 2011.
Based on the Atmosphere Monitoring Services, the level of depletion identified over the Arctic was high comparing to previous years. The reports from Copernicus Sentinel-5P satellite revealed that the depletion was severe of altitudes around 18km. The last time such strong depletion was observed over the Arctic was during spring of 2011.
The foremost reason that caused the depletion of layer and formation of hole over the Arctic is because of phenomenon called 'Polar vertex'. Polar vertex is caused because of the cold air surrounded at North poles, which is basically a low-pressure area. As outlined by the agencies, the Arctic stratosphere was recorded to be very low for several months at the start of 2020. This caused the formation of the polar stratospheric clouds associated with the polar vortex, which caused high ozone depletion over the Arctic which doesn't occur over a decade nearly.
Since, the ozone layer protect us from the direct exposure to ultraviolet radiation of the sun, the largest ozone hole could have turned as a straight threat to human if it didn't closed.
