Rainbows are frequently represented in Western art and culture, as a sign of hope and promise of better times to come. However, the hope expressed in a rainbow is frequently tinged with pathos.
Additionally, what does a rainbow cloud sign mean?
A rainbow cloud can occur because of something called cloud iridescence. It usually happens in altocumulus, cirrocumulus, lenticular and cirrus clouds. Iridescent clouds happen because of diffraction – a phenomenon that occurs when small water droplets or small ice crystals scatter the sun’s light.
