Cumulus arcus clouds have a gust front, [26] and cumulus tuba clouds have funnel clouds or tornadoes. [27] Cumulus pileus clouds refer to cumulus clouds that have grown so rapidly as to force the formation of pileus over the top of the cloud. [28] Cumulus velum clouds have an ice crystal veil over the growing top of the cloud. [19]
Cumulus fractus (WMO genus and species) – ragged detached portions of cumulus cloud. Cumulus humilis (WMO genus and species) – small, low, flattened cumulus, early development. Cumulus mediocris (WMO genus and species) – medium-sized cumulus with bulges at the top. Cumulus pileus (WMO genus and accessory cloud) – capped, hood-shaped ...
Cumulus congestus or towering cumulus clouds are a species of cumulus that can be based in the low- to middle-height ranges. They achieve considerable vertical development in areas of deep, moist convection. They are an intermediate stage between cumulus mediocris and cumulonimbus, sometimes producing rainshowers, snow, or ice pellets. [2]
According to a recent study published in Nature Communications Earth & Environment, researchers found that shallow cumulus clouds will dissipate when only a portion of the sun is obscured during ...
Towering, dense clouds with a flat, anvil-shaped top. Develops from cumulus clouds and can reach great heights, often associated with thunderstorms.
Transformation from a mature cumulus congestus cloud to a mature cumulonimbus incus In general, cumulonimbus require moisture, an unstable air mass , and a lifting force in order to form. Cumulonimbus typically go through three stages: the developing stage , the mature stage (where the main cloud may reach supercell status in favorable ...
Cumulus clouds are low-level, puffy clouds that are white with a dark base, according to the National Weather Service. They form over land on days of clear skies due to diurnal convection, the ...
More general airmass instability in the troposphere tends to produce clouds of the more freely convective cumulus genus type, whose species are mainly indicators of degrees of atmospheric instability and resultant vertical development of the clouds. A cumulus cloud initially forms in the low level of the troposphere as a cloudlet of the species ...
