Ozone depletion over the Arctic hit a record in March. It was the largest and even worst hole recorded since 2001.
The UN World Meteorological Organization said Friday that everything is closed. This was first announced on April 23 by the Copernicus Atmosphere Monitoring Service (CAMS), the European Union’s land monitoring program.
The hole had suddenly hit a record in March due to the presence of ozone-depleting chlorofluorocarbons in the atmosphere, and an extremely cold winter in the stratosphere, WMO spokeswoman Clare Nullis said at a UN briefing at Geneva, as reported by India Today.
The hole was equal to an area 3 times the size of Greenland.
A German scientist had detected exhaustion a month ago. “In areas where the thickness of the ozone layer is maximum, the loss is around 90%,” said Markus Rex, head of the department of atmospheric physics at the German Alfred-Wegener Institute, in March, as reported by DW. .
Initially, several people on the CAMS Twitter account commented that the phenomenon was due to the global blockade of Covid-19. However, this connection of the ozone layer has nothing to do with blocking.
According to scientists, it has been powered by an unusually strong and long-lasting polar vortex, high-altitude currents that bring cold air to the polar regions. This is not related to the change in air quality.
The reason behind the healing of the ozone layer, CAMS explained, was the extremely powerful vortex with really cold temperatures inside. On the surprising phenomenon, the scientist Antje Inness said that at the moment it is not clear why the dynamics was so unusual this winter.
