[漢羅] 西 Virginia 州 ê 火虹

這个雲是發生啥物代誌? 遠方捲雲 ê 冰晶 to̍h 親像是浮 tī 天頂 ê 細片 稜鏡。 伊 ê 環地平線弧 kah 地平線 平行,外形敢若是火舌仝款,所以有人私底下 kā 叫做 火虹。 若是欲看著 環地平線弧太陽 上無愛 tī 天頂 58 度懸、捲雲愛 tī 下跤,to̍h 親像是這幅圖內底 ê 毛捲雲按呢。 足濟扁扁 ê、六角形 ê 冰晶是組成捲雲 ê 原料。 In 愛 照水平方向排好勢,才會當用仝款 ê 方式好好仔 反射太陽光。 所以這款 環地平線 較罕得 看著。 這个火虹 是這個月初 tī 美國 西 Virginia 州 ê North Fork 山 附近 翕 ê。

[English] A Fire Rainbow over West Virginia

What’s happening to this cloud? Ice crystals in a distant cirrus cloud are acting like little floating prisms. Known informally as a fire rainbow for its flame-like appearance, a circumhorizon arc appears parallel to the horizon. For a circumhorizontal arc to be visible, the Sun must be at least 58 degrees high in a sky where cirrus clouds present below – in this case cirrus fibrates. The numerous, flat, hexagonal ice-crystals that compose the cirrus cloud must be aligned horizontally to properly refract sunlight in a collectively similar manner. Therefore, circumhorizontal arcs are somewhat unusual to see. The featured fire rainbow was photographed earlier this month near North Fork Mountain in West Virginia, USA.
