Por que as nuvens parecem ter cores diferentes? A razão aqui é que cristais de gelo em nuvens cirrus distantes estão agindo como pequenos prismas flutuantes.
Às vezes conhecido como arco-íris de fogo por sua aparência de chama, um arco circumhorizon está paralelo ao horizonte. Para um arco circumhorizontal ser visível, o Sol deve ter pelo menos 58 graus de altura em um céu onde nuvens cirrus estão presentes.
Além disso, os numerosos cristais de gelo hexagonais e achatados que compõem a nuvem de cirros devem ser alinhados horizontalmente para propagar adequadamente a luz solar de maneira coletivamente semelhante. Portanto, arcos circumhorizontais são bastante incomuns de se ver.
Esta exibição de circumhorizon foi fotografada através de uma lente polarizada acima de Dublin, Ohio em 2009.
