[漢羅] 內蒙古天頂 ê 光柱

這片土地天頂是發生啥物代誌？ 相片內底 ê 光 毋是 極光，是 光柱，是一款較倚地表 ê 現象。 運氣袂䆀 ê 人，會當 tī 地球 足濟所在看著 光柱，就是 ùi 日頭 延伸出--來 ê 光。 這是 頂層大氣 ê 薄板 冰晶 反射日光造成 ê 現象。 這款 冰晶 會 tī 落到地表進前，就蒸發了了。 毋過氣溫若是低到結凍 ê 溫度，薄板 冰晶 可能會 tī 低層大氣形成，變做 雪，沓沓仔、輕輕仔 落落來。 咱就 kā 這叫做 冰晶霧。 這个時陣，這款冰晶可能會反射地面 ê 燈火，就親像是 太陽 ê 光柱。 這幅影像是頂個月 tī 中國 內蒙古 ê Wulan Butong 草埔區 翕--ê。

[English] Light Pillars Over Inner Mongolia

What's happening across that field? Pictured here are not auroras but nearby light pillars, a phenomenon typically much closer. In most places on Earth, a lucky viewer can see a Sun pillar, a column of light appearing to extend up from the Sun caused by flat fluttering ice-crystals reflecting sunlight from the upper atmosphere. Usually, these ice crystals evaporate before reaching the ground. During freezing temperatures, however, flat fluttering ice crystals may form near the ground in a form of light snow sometimes known as a crystal fog. These ice crystals may then reflect ground lights in columns not unlike a Sun pillar. The featured image was taken last month across the Wulan Butong Grasslands in Inner Mongolia, China.
