Halo around the sun

What do you call a rainbow formed by ice? An icebow, of course. Others call the phenomenon a halo, and we'll admit it does have a mystical aura. It happens in locales where the bitter cold persists despite the shining sun, like here in the Ore Mountains of Germany. When the conditions are just right, tiny ice crystals in the air will refract light into a colorful halo around the bright sun. It's a perfect complement to the snow angels you're yearning to make in this pristine blanket of white.

太阳周围的光晕

冰形成的彩虹叫什么？当然是冰山。其他人称这种现象为光环，我们承认它确实有神秘的光环。这种情况发生在尽管阳光灿烂，但严寒依然持续的地方，比如德国的俄勒冈州。当条件合适时，空气中的微小冰晶会在明亮的太阳周围折射出五颜六色的光晕。这是一个完美的补充雪天使，你渴望在这个原始的白色毯子。
