北极惊现自然奇观：白色彩虹你见过吗？1

This is the amazing moment a white rainbow streaks across the Arctic sky.

这绝对是惊人的一刻：白色彩虹横跨北极上空。

The rare phenomena, named a fog bow, was spotted by Sam Dobson during a recent expedition to the North Pole.

这一罕见的自然现象叫做雾虹，是由山姆-杜布森在最近的一次北极探险中拍摄到的。

As their ice breaking ship cruised through the chilly waters, Sam clocked the arching rainbow but was stunned to see it was completely white.

山姆所乘坐的破冰船在寒冷的冰川中航行时，山姆被眼前的弧形彩虹给惊呆了，因为这是一条纯白色的彩虹。

A fog bow is a similar phenomenon to a rainbow, but it appears as an arch in fog rather than rain. And because of the very small size of water droplets that cause fog, smaller than 0.05 millimetres, it appears as a white arc, rather than a multi-coloured one.

雾虹和彩虹是相类似的自然现象，只不过雾虹是在雾中形成而非在雨中，而且由于水滴的大小不足0.05毫米，从而形成雾气，造就了这轮白色彩虹，而不是常见的七色彩虹。
