Ozone is a gas formed in the upper atmosphere when electrical charges in the atmosphere combine with ultraviolet (UV) rays from the sun. The ozone layer absorbs the majority of the sun’s harmful UV radiation.
臭氧是大气中的电荷与来自太阳的紫外线结合时在上层大气中形成的一种气体。臭氧层吸收了太阳大部分有害的紫外线辐射。
The hole disappears and reforms every year over the Antarctic due to the unique weather patterns that create incredibly cold circling winds above the pole.
由于独特的天气模式,南极上空形成了令人难以置信的寒冷回旋风,臭氧空洞每年消失又复现。
According to the British Antarctic Survey, the hole had reached an area of 11 million square kilometres in early September, when the annual “spring warming” event kicked in much earlier than usual.
根据英国南极调查局的数据,9月初春季暖流比往年提早到来,臭氧空洞达到1100万平方公里。
In 2018, the hole reached a maximum area of 22.9 million square kilometres.
2018年,臭氧空洞的最大面积达到2290万平方公里。
In 2002, the polar vortex split in two, creating two separate ozone holes over the continent.
2002年,极地涡旋分裂成两个,在南极大陆上空形成两个独立的臭氧空洞。
Anna Jones a scientist at the British Antarctic Survey told The Independent the shape of the hole this year was “very unusual”.
