Clouds of the genus nimbostratus tend to bring constant precipitation and low visibility. This cloud type normally forms above 2 kilometres (6,600 ft) [10] from altostratus cloud but tends to thicken into the lower levels during the occurrence of precipitation. The top of a nimbostratus deck is usually in the middle level of the troposphere.
Cloud iridescence or irisation is a colorful optical phenomenon that occurs in a cloud and appears in the general proximity of the Sun or Moon. The colors resemble those seen in soap bubbles and oil on a water surface.
Overlapping clouds (in meteorology, probably duplicatus clouds) are thought to imply eternal happiness [170] and clouds of different colors are said to indicate "multiplied blessings". [170] Informal cloud watching or cloud gazing is a popular activity involving watching the clouds and looking for shapes in them, a form of pareidolia. [171] [172]

Cloud species are a set of fourteen terms used to describe the shape and structure of clouds. Each one has its name abbreviated to a three letter term. Each one has its name abbreviated to a three letter term.
These are from additional particulate matter in the sky that scatter different colors at different angles. Halos, afterglows, coronas, polar stratospheric clouds, and sun dogs. These are from scattering, or refraction, by ice crystals and from other particles in the atmosphere. They depend on different particle sizes and geometries. [3] Mirages.
Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds formed by rising thermals. The term stratus describes flat, hazy , featureless clouds at low altitudes varying in color from dark gray to nearly white. [ 2 ]
First defined scientifically by Luke Howard in an 1803 paper, [3] their name is derived from the Latin word cirrus, meaning 'curl' or 'fringe'. [4] They are transparent, meaning that the sun can be seen through them. Ice crystals in the clouds cause them to usually appear white, but the rising or setting sun can color them various shades of ...
