六月下旬,這些摩托車手在土耳其布林薩省的烏盧達山(Mount Uludağ)上公路旅行時,發現自己置身於低雲和濃霧之上。明媚的陽光直射在他們身後,從大山的一側俯瞰,可以看到美麗而大氣的雲霧之弓。這種光彩被稱為 "heiligenschein "或 "布洛肯幽靈",有時也可以從飛機甚至高樓上看到。它通常看起來像一個被明亮光環包圍的黑暗巨人。當然,黑巨人只是觀測者( 90 MB 影片)在太陽對面投下的影子。雲霧是由比雨滴還小的水滴組成的,它們折射和反射陽光,形成了光彩奪目的光環和這個範圍更大的霧弓。
原文:On a road trip up Mount Uludağ in Bursa province, Turkey these motorcyclists found themselves above low clouds and fog in late June. With the bright Sun directly behind them, the view down the side of the great mountain revealed a beautiful, atmospheric glory and fog bow. Known to some as the heiligenschein or the Specter of the Brocken, a glory can also sometimes be seen from airplanes or even high buildings. It often appears to be a dark giant surrounded by a bright halo. Of course the dark giant is just the shadow of the observer (90MB video) cast opposite the Sun. The clouds and fog are composed of very small water droplets, smaller than rain drops, that refract and reflect sunlight to create the glory's colorful halo and this more extensive fog bow.
