louds fill the skies above us and are part of our every day lives, often going unnoticed. However, there are some clouds that are so rare that you will be very lucky to see them in your lifetime. This is a list of the top 10 most rarest cloud formations (in no particular order) that for those lucky enough to see them, were caught on camera.
1. Nacreous Clouds
These rare clouds, sometimes called mother-of-pearl clouds, are 15 - 25km (9 -16 miles) high in the stratosphere and well above tropospheric clouds.
They have iridescent colours but are higher and much rarer than ordinary iridescent clouds. They are seen mostly but not exclusively in polar regions and in winter at high latitudes, Scandinavia, Alaska, Northern Canada. Lower level iridescent clouds can be seen anywhere.
Nacreous clouds shine brightly in high altitude sunlight up to two hours after ground level sunset or before dawn. Their unbelievably bright iridescent colours and slow movement relative to any lower clouds make them an unmistakable and unforgettable sight.
2. Mammatus Clouds
Mammatus are pouch-like cloud structures and a rare example of clouds in sinking air.
Sometimes very ominous in appearance, mammatus clouds are harmless and do not mean that a tornado is about to form - a commonly held misconception. In fact, mammatus are usually seen after the worst of a thunderstorm has passed.
3. Altocumulus Castelanus
Also known as jellyfish clouds due to their jellyfish-like appearance.
These formed around 17,000 ft due to when the rush of moist air comes from the Gulf Stream and gets trapped between layers of dry air. The top of the cloud rises into a jellyfish shape and long tentacles known as “trailing virga” form from rain drops that have evaporated.
4. Noctilucent Clouds
Noctilucent Clouds or Polar Mesopheric Clouds: This is an extroadinarily rare cloud formation that occurs out on the verge of space between 82km to 102 km from the earth’s surface.
Noctilucent clouds appear to be luminous yet they reflect the sunlight from the other side of the earth at night, giving them a glowing appearance.
5. Mushroom Clouds
A mushroom cloud is a distinctive mushroom-shaped cloud of smoke, condensed water vapor, or debris resulting from a very large explosion. They are most commonly associated with nuclear explosions, but any sufficiently large blast will produce the same sort of effect.
Volcano eruptions and impact events can produce natural mushroom clouds.
Mushroom clouds form as a result of the sudden formation of a large mass of hot low-density gases near the ground creating a Rayleigh-Taylor instability. The mass of gas rises rapidly, resulting in turbulent vortices curling downward around its edges and drawing up a column of additional smoke and debris in the centre to form its “stem”. The mass of gas eventually reaches an altitude where it is no longer less dense than the surrounding air and disperses, the debris drawn upward from the ground scattering and drifting back down.
6. Cirrus Kelvin-Helmholtz
Appearing as a slender, horizontal spiral of cloud, cirrus Kelvin-Helmholtz is one of the most distinctive cloud formations. However, it tends to dissipate only a minute or two after forming and, as a result, is rarely observed.
Average height is around 16,500 ft.
7. Lenticular Clouds
Lenticular clouds, technically known as altocumulus standing lenticularis, are stationary lens-shaped clouds that form at high altitudes, normally aligned at right-angles to the wind direction.
Where stable moist air flows over a mountain or a range of mountains, a series of large-scale standing waves may form on the downwind side. Lenticular clouds sometimes form at the crests of these waves. Under certain conditions, long strings of lenticular clouds can form, creating a formation known as a wave cloud.
8. Roll Clouds
A roll cloud is a low, horizontal tube-shaped arcus cloud associated with a thunderstorm gust front, or sometimes a cold front. Roll clouds can also be a sign of possible microburst activity.
Cool air sinking air from a storm cloud’s downdraft spreads out across the surface with the leading edge called a gust front. This outflow undercuts warm air being drawn into the storm’s updraft. As the cool air lifts the warm moist air water condenses creating cloud, which often rolls with the different winds above and below (wind shear).
9. Shelf Clouds
A shelf cloud is a low, horizontal wedge-shaped arcus cloud, associated with a thunderstorm gust front (or occasionally with a cold front, even in the absence of thunderstorms).
Unlike a roll cloud, a shelf cloud is attached to the base of the parent cloud above it (usually a thunderstorm).
Rising cloud motion often can be seen in the leading (outer) part of the shelf cloud, while the underside often appears turbulent, boiling, and wind-torn.
10. Stratocumulus Clouds
According to the Sapporo Meteorological Observatory, these low-altitude stratocumulus clouds were rolled into long, distinctive ribbons after becoming trapped in air currents.
While it is not uncommon for wind to form such patterns in stratocumulus clouds, photos that clearly show the clouds rolled into strips are rare, says the observatory.

~lol~ It Does Look like One~!
I love them all. Subhanallah~! There so Lovely and Astonishing~! Clouds always have been My Favorite element of Earth Since I was Child. I still Remember that I loved studying about clouds in Geography Class. Even Now Whenever I'm Wondering About in My Thought I'm Mostly Looking at Clouds. They Really Sooth me. I Wish all these Sort of Clouds formed up on top of my House T^T Still Jazakallah For Sharing~! ^w^

Top five boring clouds:
1. Stratus Clouds-
These are big, flat, low clouds that cover the whole sky. They are doubly boring as they also make drizzle, the most boring form of rain.
2. Contrails-
These are the clouds that come out of the back of planes. They never rain, which is a good thing, but sometimes they spread out to cover the sky like blankets. They are common in built-up areas near airports, and are easy to see unless those darn stratus clouds are already dizzling all over you!
3. Cumulus-
The traditional could that appears on everything from Windows XP wallpapers to the metOffice symbol for clouds! A pity, they would actually look quite nice if we didn't see them every clear day.
4. Nimbostratus-
Exactly the same as stratus, but thicker and more gloomy. To make matters worse, they are notorious rain clouds!
5. Altocumulus castellanus-
Another boring heaped cloud, only smaller and not as nice as cumulus.

But yeah, SubhanaAllah the clouds look terrific!, it's just a shame most of us will have never seen these in reality, either that or we were all asleep at the same time when these clouds were around:D

Okay!
6. Dust bunnies-
Commonly found knocking about on smooth floors, these 'clouds' only fly when sucked up a vacuum cleaner!
7. Sheep-
These are flightless clouds, commonly found in hilly areas where it is easy for them to remain in contact with their (much larger) brethren.
8. Weather symbol-
This is a very low altitude cloud mainly found in TV studios. Although it looks like a cumulus cloud at first glance, if you look closer (or go and peel it off the board) you will find that one side is covered in some kind of adhesive!
