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]
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.
Cumulus pileus (WMO genus and accessory cloud) – capped, hood-shaped cumulus cloud. Cumulus praecipitatio (WMO genus and supplementary feature) – cumulus whose precipitation reaches the ground. Cumulus radiatus (WMO genus and variety) – cumulus arranged in parallel lines that appear to converge near the horizon. Cumulus radiatus clouds ...
Towering, dense clouds with a flat, anvil-shaped top. Develops from cumulus clouds and can reach great heights, often associated with thunderstorms.
Both Jupiter and Saturn have an outer cirriform cloud deck composed of ammonia, [144] [145] an intermediate stratiform haze-cloud layer made of ammonium hydrosulfide, and an inner deck of cumulus water clouds. [146] [147] Embedded cumulonimbus are known to exist near the Great Red Spot on Jupiter.
Cumulonimbus calvus develops from cumulus congestus, [2] and its further development, under auspicious conditions, will result in cumulonimbus incus. This cloud consists mainly of water droplets. By definition of cumulonimbus cloud, at its top water droplets are transformed into ice crystals. But for cumulonimbus calvus, content of ice crystals ...
Cloud with limited vertical height with a length much bigger than their height: Cu Lenticularis: len: Lens or almond shaped clouds that are stationary in the sky: Sc, Ac, Cc Mediocris: med: Clouds of moderate height that are around equal height and length, growing upwards: Cu Nebulosus: neb: Featureless sheet of cloud with no structure: St, Cs ...
Clouds that have low densities, such as cirrus clouds, contain very little water, thus resulting in relatively low liquid water content values of around .03 g/m 3.Clouds that have high densities, like cumulonimbus clouds, have much higher liquid water content values that are around 1-3 g/m 3, as more liquid is present in the same amount of space.
