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 ...
Clouds form when the dew point temperature of water is reached in the presence of condensation nuclei in the troposphere. The atmosphere is a dynamic system, and the local conditions of turbulence, uplift, and other parameters give rise to many types of clouds. Various types of cloud occur frequently enough to have been categorized.
Towering, dense clouds with a flat, anvil-shaped top. Develops from cumulus clouds and can reach great heights, often associated with thunderstorms.
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]
If the air becomes more unstable, the cloud tends to grow vertically into the species mediocris, then strongly convective congestus, the tallest cumulus species [74] which is the same type that the International Civil Aviation Organization refers to as 'towering cumulus'. [9] Cumulus mediocris cloud, about to turn into a cumulus congestus
Convective rain and light precipitation are the result of large convective clouds, for example cumulonimbus or cumulus congestus clouds. In the initial stages of this precipitation, it generally falls as showers with a smaller area and a rapidly changing intensity.
A cumulonimbus incus is a mature thunderstorm cloud generating many dangerous elements. Lightning: this storm cloud is capable of producing bursts of cloud-to-ground lightning. Hail: hailstones may fall from this cloud if it is a highly unstable environment (which favours a more vigorous storm updraft).
