i like cool clouds and i think we dont talk about them enough
there are like, a LOT of really weird clouds that i genuinely wouldn't know how to show them off in any coherent order besides putting Clouds I Like.
these are Kelvin-Helmholtz clouds (also known as the Kelvin-Helmholtz wave). "They occur when there is a strong vertical shear between two air streams, causing winds to blow faster at the upper level than at the lower levels."
theyre just really cool looking :).
these are double helix clouds and they're VERY rare, and kinda hard to explain without citing a source. "they're a form of Kelvin-Helmholtz instability and the structure is called (aptly enough) a braid."
despite being rare, the few that have existed have been documented and researched, starting in 2012.
mammatus clouds are formed because of cold air sinking down to form the pockets contrary to the puffs of clouds rising through the convection of warm air. it kinda reminds me of when you put oil in a cup of water. there are a couple of different kind of mammatus clouds, but they usually result in a similar visual outcome.
asperitas clouds name translates to "roughness" and it was first documented in 2009, being included to the cloud atlas in 2017! "Like mentioned in a previous article on Kelvin-Helmholtz Instability, atmospheric and fluid dynamics play a role in the origins of these clouds. Shifting wind directions and velocities appear to cause Asperitas’ wave-like structure, much like how velocity and current direction influences a fluid. Winds shifting in the horizontal and vertical direction is thought to help create the structure of these clouds.."
i personally like to call them asparagus clouds because i dont know how to pronounce asperitas and i think asparagus clouds is a way better name.
arcus clouds
there are two types, both listed below. an arcus cloud is a low, horizontal cloud formation, usually appearing as an accessory cloud to a cumulonimbus (a storm cloud). the first pair of images is a shelf cloud.
" they're formed by the rising cloud motion which can often be seen in the leading (outer) part of the shelf cloud, while the underside can often appear as turbulent and wind-torn. Cool, sinking air from a storm cloud's downdraft spreads out across the land surface, with the leading edge called a gust front. This outflow cuts under warm air being drawn into the storm's updraft."
the second pair are morning glory clouds, which is a rare meteorological phenomenon that can happen to certain roll clouds. they're most common (and easy to predict) in Australia. "One of the main contributors for the formation of the morning glory clouds is the mesoscale circulations associated with a difference in sea breezes that develop over the Peninsula and the Gulf."
lenticular clouds are cool to me because it's very likely that a majority of UFO sighting ARE THESE BABIES RIGHT HERE!! something about that is really cool to me, and i've also included some photos of the clouds at night so you can see the confusion. "they form because as air travels along the surface of the Earth, obstructions are often encountered, including natural features, such as mountains or hills, and artificial structures, such as buildings and other constructions, which disrupt the flow of air into "eddies", or areas of turbulence.
When moist, stable air flows over a larger eddy, such as those caused by mountains, a series of large-scale standing wave forms on the leeward side of the mountain. If the temperature at the crest of the wave drops below the dew point, moisture in the air may condense to form lenticular clouds."
these two arent inherently clouds, and more so have to do WITH clouds.
"fallstreak holes are a large gap, usually circular or elliptical, that can appear in cirrocumulus or altocumulus clouds. The holes are caused by supercooled water in the clouds suddenly evaporating, and may be triggered by passing aircraft."
they're SO cool looking, and i like the way they can be caused by aircrafts, meaning its influenced by humans. thats the part of nature i find cool, is the way we interact with our ecosystem and biosphere.
on the side of rainbows, this is a form cloud iridescence that happened in china. "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. It is a type of photometer. This fairly common phenomenon is most often observed in altocumulus, cirrocumulus, lenticular, and cirrus clouds."
theyre just really cool and i like gay clouds
these two kind of parallel each other, but also, they kinda Do Not. i love them both either way.
"Noctilucent clouds are tenuous cloud-like phenomena in the upper atmosphere of Earth. They consist of ice crystals and from the ground are only visible during astronomical twilight."
but from space?
THATS so cool to me. you can see that fucker from space!!
the aurora borealis on the other hand is something i find very cool, but very VERY terrifying. "they're the polar lights and are a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic)."
the part that terrifies me is this: "Auroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles."
like....yeah. yikes. beautiful but damaging and terrifying :)
oh yeah heres that baby from space by the way!!
