This is the main precipitating type, however any rain is usually light. Continue with Recommended Cookies. Both stratocumulus and cumulus clouds are found at the same height, but stratocumulus clouds are more of a layer cloud than a cumulus cloud, usually found in conjoined groups or clumps of clouds. Stratocumulus usually occur as a distinct extensive layer or sheet of grey to white low clouds, in the form of more or less regular clumbs or patches often arranged in bands or rolls that lie across the wind. Any opinions, findings and conclusions or recommendations expressed in this material do not necessarily reflect the views of the National Science Foundation. They attract water vapor and as they ascend the vapor condenses to form liquid water or ice, which results in the formation of tiny globules called cloud droplets. More dramatic versions of stratocumulus clouds include (but arent limited to) chaotic and wavy features (asperitas), sac-like features (mamma), and can even have the rare kelvin-helmholtz wave cloud (fluctus) association. Cumulonimbus clouds are also called thunderstorms, since they usually have lightning and thunder associated with them. In this lesson, learn about what stratocumulus clouds are, including what they look like, how they form, and the type of weather they bring. When Nature Strikes: Wildfires - Why are they a challenge to stop? If the cloud is about the size of your fist, then it is stratocumulus. Stratocumulus Cumulomutatus the specific type of stratocumulus clouds, are flat and elongated.

Most of us can probably remember a time when we were lying in the grass and gazing up at the blue sky. [6] It was suggested that this finding could help explain past episodes of unusually rapid warming such as Paleocene-Eocene Thermal Maximum[7] In 2020, further work from the same authors revealed that in their large eddy simulation, this tipping point cannot be stopped with solar geoengineering: in a hypothetical scenario where very high CO2 emissions continue for a long time but are offset with extensive solar geoengineering, the break-up of stratocumulus clouds is simply delayed until CO2 concentrations hit 1,700 ppm, at which point it would still cause around 5C (9.0F) of unavoidable warming. A simple test to distinguish these is to compare the size of individual masses or rolls: when pointing one's hand in the direction of the cloud, if the cloud is about the size of the thumb, it is altocumulus; if it is the size of one's fist, it is stratocumulus. As they rise and fall, they may appear in infinite variations. The consent submitted will only be used for data processing originating from this website. A stratocumulus cloud, occasionally called a cumulostratus, belongs to a genus-type of clouds characterized by large dark, rounded masses, usually in groups, lines, or waves, the individual elements being larger than those in altocumulus, and the whole being at a lower height, usually below 2,000 metres (6,600ft). Altocumulus clouds usually form in groups and are about one kilometer thick.
