Rainbow-like cloud leaves citizens of Chinese city in awe: All you will need to know about Pileus
Citizens of China’s Haikou town have been left stunned when they spotted a unique phenomenon in the sky: a rainbow, but in the condition of a cloud. On the other hand, the phenomenon was not a rainbow but, in truth, a cloud.
Pileus cloud
What was observed in the skies of Haikou on August 21 is referred to as a ‘Pileus cloud’, also recognised as a ‘cap cloud and ’scarf cloud’. In accordance to The Weather Community, a pileus is formed when the rapidly increasing air in the updraft of a towering cumulus cloud (also referred to as a cumulonimbus) pushes versus the cooler air higher than it. This will cause condensation of the dampness suitable alongside the top rated of the updraft, major to the formation of the Pileus.
When the daylight is at the appropriate angle, diffraction of gentle requires area in between the droplets and ice crystals in the cloud, giving the Pileus its colors, which resemble those in a rainbow.
Having said that, these clouds typically have a pretty shorter existence. This is since these get ‘eaten up’ by the cloud on major of which they seem the lessen cloud rises up by convection to take up Pileus.
