(ORDO NEWS) — Experts note the fact that ozone holes appear extremely rarely over the Arctic, but in the near future the situation may change dramatically.
They conducted a study, the results of which showed that the huge ozone hole that arose over the Arctic last year was the result of low temperatures in the North Pacific Ocean. This is reported by Science Alert.
This hole was closed in the spring, but experts believe that in the future it may appear again. They applied computer simulations, as well as data obtained from satellites, and found that high temperatures in the North Pacific Ocean can lower the temperature of those westerly winds that are present in the Arctic in winter and early spring.
It is they that provoke the appearance of special polar clouds of the stratospheric type. The presence of clouds in the stratosphere of the planet is the main reason for the destruction of the ozone layer.
Yong Yun Hu noted that such a huge loss of the ozone layer has led to severe depletion. The results of the study showed that in the future the situation may repeat itself if the weather processes are too strong.
The ozone layer is a special layer of gas that is located in the upper atmosphere of our planet and protects it from ultraviolet radiation, which is dangerous to human life. For the first time, the depletion of the ozone layer was noticed by scientists in the 70s of the last century.
