雪在我们印象中一直是洁白无瑕的,但是近日东欧多个地区却惊现“橙色雪”,这场可怕的橙色暴风雪将大片雪白的山脉变成了赤褐色,火星般的场景让人怀疑是末日降临。那么这种诡异的颜色是如何形成的?来看看气象学家怎么说。
A recent fall of really strange orange-tinted snow is making headlines after it swept across a swathe of Eastern Europe. Images on social media from Russia show mountainous landscapes tinged auburn, where usually they are pristine white.
最近东欧多地上空飘起橙色雪,这一奇特景象抢占了资讯头条。俄罗斯社交媒体的图片显示,往常雪白的大片山脉被染成了赤褐色。
Although it resembles what we might imagine snow on Mars to look like, the explanation is actually pretty simple.
尽管它看上去像极了我们想象中的“火星雪”,但是这个现象背后的原因其实很简单。
According to the BBC, the orange colouration is caused by fine particles of sand being lifted from the Sahara into the atmosphere, travelling across the world and falling back to the ground mixed in with rain and snow.
据BBC报道,雪的橙色调源于撒哈拉沙漠飘来的细沙,这些细沙经历了“环球旅行”,最后混在雨雪中降落到地面。
It occurs once every five years or so - although this year's orange snow is particularly vibrant, due to a desert sandstorm that was so big it was seen in NASA satellite imagery travelling across the globe, CNN reports.
