10 Most Beautiful in the World of Cloud Forms

The sky without a cloud like a garden without flowers . The cloud can be generally classified by appearance : cumulus ( stacked ) , stratus ( layered ) , cirrus ( circles ) , nimbus ( rain ) . Can also be distinguished by the height of the cloud is essentially : high level , mid-level , low-level clouds and vertical clouds .
Here's 10 Most Beautiful in the World of Cloud Forms :
1 . Polar stratospheric clouds

Polar stratospheric clouds form in the stratosphere at an altitude of 50,000 to 80,000 feet . These clouds are classified into Type I ( clouds form more diffuse and less bright colors ) . Unfortunately , Polar stratospheric clouds play a key role in the massive ozone depletion over the Arctic and Antarctic . NASA explains that this cloud is formed only at very low temperatures . In recent years , the atmosphere over the Arctic colder than usual , and this polar stratospheric clouds continued until the spring . As a result , ozone levels continue to decline .
2 . Jacques Cousteau cloud

Jacques Cousteau cloud , or also can be called undulatus asperatus . The official name undulatus clouds asperatus taken because the undulation shape can be described as a cloud of highly turbulent and chaotic . According to Guardian.co.uk , the Roman poet Virgil asperatus use the word in a poem to describe the wavy sea surface due to the north wind .
3 . Noctilucent clouds


Noctilucent clouds appeared several times in Europe and the United States . Scientists believe that they arise because it is caused by global warming . Because this phenomenon is basically new , apparently more questions than answers to this cloud phenomenon . Type of cloud was first observed 126 years ago by an amateur astronomer . Located in the mesosphere layer , noctilucent clouds are the highest clouds in the world . Clouds that form 50 miles above Earth's surface are generally colorless , although there are some pale blue , dark green , light yellow and sometimes red .
4 . Anvil clouds

Anvil clouds are also known as cumulonimbus incus , consisting mostly of ice particles . This cloud is a storm cloud that has matured that a time may cause a storm and then a tornado . Cumulonimbus clouds are divided into two species : calvus and capillatus . There are enough interesting facts from the clouds , where the anvil clouds that are at the highest levels often contain heavy snow due to the very cold upper layer . The snow then melts into rain when it falls into a layer of warm air in the lowlands . According WeatherQuestions.com , 40 to 50 % of the rain that is produced by the average storm originated as ice and snow , even for storms that occur in the tropics .
5 . Lenticular clouds

These clouds are usually formed due to gravitational waves . Stationary clouds can be classified into cirrocumulus standing lenticular ( CCSL ) , altocumulus standing lenticularis ( ACSL ) and stratocumulus standing lenticular ( SCSL ) . Because of its amazing forms , lenticular clouds are often mistaken mistaken for a UFO .
6 . Morning Glory clouds

Morning Glory cloud is a rare phenomenon and dramatic . The cloud rolls occurs in the lower layers of the atmosphere ahead of the storm and can most often be observed in Northern Australia . Morning Glory clouds also been found in Germany , Central America , the English Channel and the East of Russia . This cloud length can reach up to 1000 km and sometimes there are up to seven or eight clouds are lined in a row . Despite being studied for over 70 years by scientists , remarkable atmospheric phenomena can not be clearly understood .
7 . Mammatus clouds

Mammatus cloud is a cloud formation that looks odd . Also known as mammatocumulus , they are often associated with the occurrence of severe storms . These clouds are formed due to convection and the buoyancy of the air . evaporation causes pockets of negative buoyancy so that the cold air trapped in the cloud . This makes the clouds puff downward instead of up like cumulus clouds , and they end up being like a reverse bubble .
8 . Shelf clouds

Shelf cloud is like a shelf protruding from their parent thunderstorm clouds . This cloud formation associated with the phenomenon known as the " gust front " . This type of cloud is often mistakenly thought to be a wall cloud . The difference is that clouds usually appear on the back wall of the storm , while Cloud Shelf in the front edge of the storm .
9 . Cirrus clouds radiatus


Cirrus radiatus clouds can be found in a variety of shapes and sizes and occur in the coldest and highest regions of the troposphere . Cirrus clouds are delicate and thin radiatus appear to converge to a single point on the horizon . The funny thing is that they only become parallel to each other and cirrus radiatus clouds were never united at all .
10 . Kelvin - Helmholtz wave clouds

Kelvin - Helmholtz wave clouds look like ocean waves were crashing . This beautiful cloud named after its discoverer , namely two German physicist Hermann von Helmholtz and called his friend who is also a British physicist Lord Kelvin . These clouds are formed when two different layers of air moving past each other at different speeds . These clouds are often used as indicators for atmospheric instability .
