Flammagenitus (cloud) This is a process not yet fully understood, but is probably in some way associated with charge separation induced by severe turbulence, and, perhaps, by the nature of the particles of ash in the cloud. Large flammagenitus can contain temperatures well below freezing, and the electrostatic properties of any ice that forms may also play a role. A flammagenitus that produces lightning is actually a type of cumulonimbus, a thundercloud, and is called cumulonimbus flammagenitus. The World Meteorological Organization formerly classified flammagenitus and cumulonimbus flammagenitus respectively as cumulus (mediocris or congestus) and cumulonimbus. In 2017, the WMO International Cloud Atlas
Stratocumulus cloud with two or more layers or sheets. Stratocumulus duplicatus is common on species lenticularis or lenticular cloud. Stratocumulus Lacunosus clouds are very uncommon. They only occur when there are localized downdrafts striking through the stratocumuliform cloud. Stratocumulus Mamma is a type of mammatus cloud. Stratocumulus Virga is a form of precipitation that evaporates in mid-air and doesn't reach the ground. Stratocumulus Praecipitatio is a form of precipitation that reaches the ground as light rain or snow. Stratocumulus Cumulomutatus the specific type of stratocumulus clouds, are flat and elongated. They form in the evening, when updrafts caused by convection decrease making
