They’re formed when tiny water droplets or ice crystals are lingering in the air and refracting the sunlight. Meteorologist Haley LaPoint explains the optical phenomenon that causes clouds to take on a rainbow color. Mar 21, 2016 - The term cloud iridescence - aka irisation - comes from Iris, the Greek personification of the rainbow. Nacreous. Larger ice crystals produce halos, which are a refraction phenomena rather than iridescence. Fun Fact – The term iridescent comes from the Greek goddess, Iris, who was the personification of a rainbow. scijinks.gov. The iridescent clouds were a break of beauty in the midst of Storm Henry, which brought 90 mph winds and the threat of coastal flooding to Scotland, weather.com U.K. reports. Other examples of iridescence caused by interference include ice and crumpled cellophane, which will produce iridescent colors in polarized white light. Ice polar stratospheric clouds (nacreous clouds) form at temperatures below the ice frost point, typically near −85 °C, which is colder than the average lower stratosphere temperature.The characteristic bright iridescent colours, resulting from diffraction and interference of light waves, suggest that the clouds are composed of similarly … For example, light waves can interfere with one another, causing the iridescent colors you see in a layer of oil on a wet pavement or in the surface of a soap bubble. It produces a vast range of rainbow-like colours in clouds resulting from the light that beams from the Sun, or even the Moon in some cases.

These rare clouds, sometimes called mother-of-pearl clouds, are 15 – 25km (9 -16 miles) high in the stratosphere and well above tropospheric clouds. Clouds iridescence in polar stratospheric. The rainbow forms as ice crystals in the cloud cause the light to be split, just like a prism would. Iridescent clouds are a diffraction phenomenon cause by small water droplets or small ice crystals individually scattering light. What affects the surface characteristics of cumulus clouds? A mix of chemistry, physics and geometry are the main components for sun halos. A variety of structural features interact with light to create iridescence.

Noctilucent clouds, or night shining clouds, are tenuous cloud-like phenomena in the upper atmosphere of Earth.They consist of ice crystals and are only visible during astronomical twilight. The effect is similar to irisation. ... 13 Gorgeous Photographs of Iridescent Clouds that Illuminate the Sky with Vibrant Rainbows. And when they occur near the sun, it can be difficult for us to spot for it can get drowned in the sun’s glare. These clouds are formed of small water droplets of nearly uniform size.
