A look at some beautiful cloud formations.
Cloud formations have always been fascinating.
Over the years, studying unusually formed clouds has led to a cloud classification system which is consistent throughout the world.
The nomenclature system for clouds was first introduced by amateur meteorologist, Luke Howard, in 1802.
As of today, cloud classification is done on the basis of the process of formation, altitude and a few other features.
Fortunately, you do not have to be a meteorologist to just sit back and enjoy the beauty of it.

3. Polar Stratospheric Cloud

Polar Stratospheric Cloud, or the nacreous cloud, derives its name from 'nacre' or the mother of pearl. These are formed in the winter at the polar stratosphere and are best seen when the sun is between 1 and 6 degrees below the horizon. (Photo courtesy - Wikimedia Commons)
4. Roll Cloud

Roll clouds are one of two types of Arcus clouds, the other being the shelf cloud. Roll clouds are generally low, horizontal, tube-shaped and comparatively rare. (Photo courtesy - Wikimedia Commons)
5. Asperitas, or Undulatus Asperatus
)
Undulatus asperatus was deemed a separate classification in 2009 by the Cloud Appreciation Society. Even though they may seem dark and moisture-laden, these type of clouds tend to dissipate quickly. (Photo courtesy - Wikimedia Commons)
