- The C3S (Copernicus Climate Change Service) and CAMS (Copernicus Atmosphere Monitoring Service) confirmed that the hole in the Ozone layer has healed itself.
- The main reason for the hole to heal by itself is the polar vortex.
- According to the scientists the closure of the hole is not due to the reduced pollution levels due to COVID-19 lock down.
- The hole was 1 million square kilometres wide above the Arctic.
- It was the largest pole that was found in the history of Ozone layer.
- It was formed due to unusual climatic conditions.
- The Polar Vortex is a winter phenomenon.
- The polar vortex has been recorded to be extremely powerful, and temperatures inside it have been very cold.
- Polar Vortex is cyclonic circular winds that blow in the stratosphere from west to east.
- Polar Vortex extends from tropopause through the stratosphere and into the mesosphere.
- When the vortex is strongest, cold air is less-likely to plunge deep into North America or Europe.
- Ozone layer is found mainly in the upper atmosphere, an area called the stratosphere, between 10 and 50 km from the earth’s surface.
