The phenomenon may happen again.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. Scientists from the Beijing University explain the formation of a huge ozone hole over the Arctic last year with a temperature anomaly. This is reported by with reference to the publication Advances in Atmospheric Sciences.

The researchers noticed that the waters of the North Pacific Ocean warmed up to a record last winter, while the westerly winds of the Arctic, on the contrary, became colder. Freezing winds led to the formation of polar clouds in the stratosphere, a key component of ozone depletion. The hole has already closed, but if the temperature anomalies happen again, it will reappear.

The 2011 ozone hole, the appearance of which scientists could not explain for a long time, may also be associated with the temperature anomaly. They warned that with further warming, the ozone layer over the Arctic could continue to degrade.

Earlier it became known that global warming is activating viruses in the Arctic.
