Cloud murus cloud and is the result of air feeding into the storm. Supplementary cloud formations detached from the main cloud are known as accessory clouds. The heavier precipitating clouds, nimbostratus, towering cumulus (cumulus congestus), and cumulonimbus typically see the formation in precipitation of the "pannus" feature, low ragged clouds of the genera and species cumulus fractus or stratus fractus. A group of accessory clouds comprise formations that are associated mainly with upward-growing cumuliform and cumulonimbiform clouds of free convection. "Pileus" is a cap cloud that can form over a cumulonimbus or large cumulus cloud, whereas a "velum" feature is a
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
