There are many kinds of cloud formations above in the sky. You can experience if you watch the sky daily and try to observe the change in patterns of the clouds. Let me tell you there are many different kinds of cloud formations above in the sky. So, here we are listing the 10 most astonishing and unbelievable cloud formations that look beautiful and terrifying at the same time. There are many cloud formation that you have observed and there are many which are very rare to watch. Clouds also signify nature beautiful gift in terms patterns and rains that we are very much dependent upon. So, here is the beautiful and astonishing cloud formation that you should know so that when you look into the sky you can relate the pattern with the name.
Astonishing and Unbelievable Cloud Formations
1. Mammatus Cloud
It is also known as also known as the mammatocumulus meaning mammary cloud. These cloud formation usually was seen after the thunderstorm has been passed. It is like a pattern of pouches hanging underneath the base of a cloud which looks beautiful.
2. Shelf Cloud
A Shelf cloud is a low and horizontal shaped cloud. They are usually seen after the thunderstorm or the cold front. Most false tornado and false funnel cloud reports are associated with shelf clouds. There is only one difference between the self-cloud and roll cloud is that the shelf cloud is directly attached to the parent cloud.
3. Cirrus Kelvin-Helmholtz Cloud
This cloud formation is very rare to watch as they disappear very quickly. The main reason for the formation of these clouds is velocity difference across the interface between two fluids. This form of instability has been studied by Lord Kelvin and Hermann von Helmholtz and thus the name of the cloud formation is given.

4. Noctilucent Cloud
These cloud formations are also very rare and last understood cloud formation that exists in our earth atmosphere. These are also highest cloud formation and usually formed 80 km in the sky. They are usually visible in twilight and it also depends on many factors. The clouds are made up of water ice.
5. Altocumulus Castellanus Cloud
They are also called jellyfish clouds because of their appearance as you can see in below picture. They are usually formed when the rush of moist air comes from the Gulf Stream and gets trapped between layers of dry air.
6. Mushroom Cloud
These cloud formations are of smoke and condensed water vapor. These are the results of a very large explosion like a nuclear explosion and volcanic eruption also any sort of large explosion can result in the formation of these clouds. The reason for the formation of this cloud is when hot low density gaseous near the ground creates Rayleigh-Taylor instability.
7. Lenticular Cloud
They are also known as altocumulus standing lenticularis. These clouds are also very rare to watch. They have an appearance of stationary lens-shaped clouds and are usually formed at very higher altitudes. They usually are at 90 degrees to the direction of the wind direction. The reason for the formation of these clouds is the moist air when flows through the mountains resulting in the formation of waves on the downwind side and some of them take the form of the wave cloud.
8. Roll Cloud
They are also usually seen after the thunderstorm and cold fronts. These are also formed of arcus cloud. These cloud formations are also because of microburst activity. These cloud formations are very low and tube-shaped.

9. Stratocumulus Cloud
These cloud formations are usually classified in large dark and rounded masses. The formations are usually occurring in groups, lines, and waves. They also formed at a lower altitude. The reason for the cloud formation is the weak convective currents that create shallow layers because of the above stable air.
10. Punch Hole Cloud
These cloud formations are also known as fallstreak hole. They are usually seen with UFO sightings. The reason for the cloud formation is when the water temperature in the clouds is below freezing but the water hasn’t frozen yet.
