journalNature Geosciencefound that the wet conditions of Northern Europe continued weeks after the particularly low levels of ozone in the Arctic spring. discovered. Warmer and drier conditions in Southern Europe.
The Earth'sozone layer in the atmospherehelps absorb potentially harmful UV rays from the Sun. In recent decades, certain gas emitted by humans has damaged this layer.
Ozone holes in Antarctica have been shown to affect the weather in the Southern Hemisphere, but until now it was not clear if a similar phenomenon would occur in the Northern Hemisphere.
Marina Friedel of the ETH Zurich University in Switzerland and her co-authors have found that depletion of the ozone layer in the Arctic in spring leads to a cooler stratosphere, the second layer of the Earth's atmosphere. .. This cooling then extended the existence of thepolar vortex. The high wind circulation in the stratosphere allows the cold Arctic air to be carried south.
This causes anomalies in surface temperature and rainfall in the Northern Hemisphere, the authors said.
In the same week, we received news that"huge" ozone holeswere identified in the Earth's atmosphere in almost all of the tropics. The
holeis the annual gap in the planet'sozonelayer, seven times the size of the famous Antarctic ozone hole that opens each year. .. Spring.
