Identifying the fractuscloud species
A species of cumulus or stratus cloud with a fractured, shredded appearance
The ‘fractus’ cloud species is found in only low-altitude cumulus and stratus cloud types, and is one of only two species that’s associated with stratus clouds. Translated from latin meaning broken, their cloud abbreviations can be respectively written as ‘Cu fra’ and ‘St fra’. Fractus clouds are sometimes referred to as scud clouds and can best be described as ragged cloud shreds constantly changing shape.
It’s not always easy to distinguish cumulus fractus from stratus fractus. One suggested way to determine the cloud type is by studying the surrounding conditions and clouds that are in the vicinity. If the cloud in question shows very little detail and is surrounded by other stratus clouds, it might be a telling sign of a stratus fractus.
On a clear, fair-weather day, if you see fractus clouds, chances are you’re looking at cumulus fractus. Similar to fractus clouds, the floccus cloud species can have a ragged appearance as well, but usually are more robust and not as broken up. The pannus cloud accessory is essentially type of fractus cloud that accompanies other cloud types such as altostratus, nimbostratus, cumulonimbus, and sometimes cumulus congestus.
Other kinds of clouds associated with fractus clouds include stratus silvagenitus (forest evaporation) as well as stratus cataractagentius (waterfall condensation). Fractus cloud formations are a fairly common species when cumulus and stratus clouds are present.
