[漢羅] 雲頂 ê 極光

極光一般來講會 tī 雲 ê 面頂出現。 極光 是 ùi 太陽噴出來 ê 快速運動粒子 碰著 地球磁層 產生 ê。 Tī 遐,踅 地球磁場 ê 帶電粒子,會碰著 地球大氣層 較懸所在 ê 原子 kah 分子。 像 酸素 原子,若是去予這款相碰激發了後,to̍h 會發出青色 ê 極光。 低層 ê 極光 會發生 tī 100 公里懸以上 ê 所在。 是講大部份 ê 雲干焦會出現 tī 10 公里懸以下 ê 所在。 這張 2015 年 tī 冰島 Dyrholaey 翕 ê 相片,to̍h 看會當清楚看著雲 kah 極光 ê 相對懸度。 Tī 遐, 有一位天文攝影師,為著欲翕著這个 媠甲親像一幅圖 ê 燈塔 面頂 ê 極光,決定忍受 強風 kah 彼陣 ê 烏陰天。 結果 tī 路 lih 煞翕著這張有搝長 透鏡雲 ê 相片。

[English] Aurora over Clouds

Auroras usually occur high above the clouds. The auroral glow is created when fast-moving particles ejected from the Sun impact the Earth’s magnetosphere, from which charged particles spiral along the Earth’s magnetic field to strike atoms and molecules high in the Earth’s atmosphere. An oxygen atom, for example, will glow in the green light commonly emitted by an aurora after being energized by such a collision. The lowest part of an aurora will typically occur about 100 kilometers up, while most clouds exist only below about 10 kilometers. The relative heights of clouds and auroras are shown clearly in the featured picture in 2015 from Dyrholaey, Iceland. There, a determined astrophotographer withstood high winds and initially overcast skies in an attempt to capture aurora over a picturesque lighthouse, only to take, by chance, the featured picture including elongated lenticular clouds, along the way.
