what causes a rainbow in the clouds?

Iridescent clouds, known as "fire rainbows" or "rainbow clouds," occur when sunlight diffracts off water droplets in the atmosphere. And the recipe for these heavenly sights is actually pretty simple. Like common cloud-to-ground rainbows, iridescent clouds usually accompany thunderstorms.

Cumulus clouds result from air rising due to positive buoyancy (i.e. metaphor: bubbles rising in a pot of water). Stratus clouds results from a forced lifting of air (low level convergence, upper level divergence). Cumulus clouds are associated with convection.

Iridescent clouds, known as "fire rainbows" or "rainbow clouds," occur when sunlight diffracts off water droplets in the atmosphere. ... And sometimes moisture in that air suddenly condenses into tiny droplets to form a cap cloud." This "cap"—which scientists call a "pileus"—is the source of the brilliant spectacle.

Rainbows are formed when sunlight is scattered from raindrops into the eyes of an observer. ... The lower the sun in the sky the more of an arc of a rainbow the viewer will see. Rain, fog or some other source of water droplets must be in front of the viewer.

Cloud. The presence of three or more pinpoint inclusions close together can create an area of haze, or a cloud, in the diamond. While the occurrence of a small cloud is not visible to the naked eye, presence of many pinpoints covering a large area can affect the clarity of the diamond.

What is a double rainbow? Double rainbows are formed when sunlight is reflected twice within a raindrop with the violet light that reaches the observers eye coming from the higher raindrops and the red light from lower raindrops.

The rainbows aim to make people smile while they're walking by, and also offer a message of hope. Rainbows are used as a symbol of peace and hope as they often appear when the sun follows a heavy rainfall. They serve to remind us that there is hope and light to follow even after dark times.

From what I can tell, they are formed when there's rising air that creates wide-spread cloud cover, together with wind shear that blows across the rising air. This can set up gravity waves, where air moves up and down as buoyancy and gravity battle it out, creating long rippling waves that carry the clouds up and down.

Rainbows aren't just arcs in the sky — they're actually full circles. Rainbows are one of nature's most stunning displays. They form when light enters and bends out of raindrops in the air.

The second and more faint rainbow is called the secondary rainbow. It occurs when refracted light does not escape the raindrop after being reflected the first time.

There are three main types of clouds. The stratus, the cumulus, and the cirrus.

Even when it is very warm and sunny, there might not be any clouds and the sky is a clear blue. The usual reason for the absence of clouds will be the type of pressure, with the area being under the influence of a high pressure or anticyclone. Air would be sinking slowly, rather than rising and cooling.

Spiritual Meaning of Rainbow Clouds It is a sign of hope, promise, and inspiration. Whenever you feel that you are losing hope and you come across a rainbow cloud, think of it as a sign from the angels who are trying to give you hope.

The term cloud iridescence – aka irisation – comes from Iris, the Greek personification of the rainbow. True iridescent clouds are relatively rare.

Bottom line: Halos around the sun or moon are caused by high, thin cirrus clouds drifting high above your head. Tiny ice crystals in Earth's atmosphere create the halos. They do it by refracting and reflecting the light. Lunar halos are signs that storms are nearby.

The different types of clouds are cumulus, cirrus, stratus and nimbus.
