Description
This is love: to fly toward a secret sky, to cause a hundred veils to fall each moment. First, to let go of life. In the end, to take a step without feet; to regard this world as invisible, and to disregard what appears to be the self - Rumi
Iridescent Clouds, Diffraction and Prismatic Colours - Atmospheric Optics
Iridescence in clouds most often occurs close to the sun. It is best seen when the sun is hidden. When parts of clouds are thin and have similar size droplets, diffraction can make them shine with colours like a corona. In fact, the colours are essentially corona fragments. The effect is called cloud iridescence or irisation, terms derived from Iris the Greek personification of the rainbow.
The usually delicate colours can be in almost random patches or bands at cloud edges. They are only organised into coronal rings when the droplet size is uniform right across the cloud. The bands and colours change or come and go as the cloud evolves.
They occur most often in altocumulus, cirrocumulus and especially in lenticular clouds. Iridescence is seen mostly when part of a cloud is forming because then all the droplets have a similar history and consequently have a similar size. Sometimes iridescence may be seen far from the sun but is most frequently near to it.
