雾虹是一种与彩虹相似的天气现象，其在空中出现时，看起来像是一座拱形雾门。由于雾虹中水滴太小，无法像彩虹中的水滴那样反射出七彩颜色，因此人们只能看到白色。 Rare white rainbow ①lights up the North Pole This is the amazing moment a white rainbow streaks across the Arctic sky. ②The rare phenomena, named a fog bow, was spotted by Sam Dobson during a recent expedition to the North Pole. As their ice breaking ship cruised through the chilly waters, Sam clocked the arching rainbow but was stunned to see it was completely white. ③A 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 millimeters, it appears as a white arc, rather than a multi-coloured one. 罕见白色彩虹耀现北极 这绝对是惊人的一刻：白色彩虹横跨北极上空。 在最近的一次北极探险中，这称为雾虹的稀有现象被山姆•杜布森拍摄到。 当山姆-杜步森他们的破冰船在寒冷的冰川中巡航时，山姆抓拍了这令人惊讶的彩虹，但是当他看到这条彩虹的时候，他完全惊呆了因为它是纯白的。 雾虹和彩虹是类似的自然现象，但是它出现在北极的雾天中而不是在雨中。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。 1. streak [stri:k] n.（与周围有所不同的）条纹， 2. phenomena [fiˈnɔminə] n. 现象 3. spot [s
