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 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 ...
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
Develops from cumulus clouds and can reach great heights, often associated with thunderstorms. Indicates severe weather, such as thunderstorms, heavy rain, hail, and sometimes tornadoes.
Towering cumulonimbus clouds are typically accompanied by smaller cumulus clouds. The cumulonimbus base may extend several kilometres (miles) across, or be as small as several tens of metres (yards) across, and occupy low to upper altitudes within the troposphere - formed at altitude from approximately 200 to 4,000 m (700 to 10,000 ft).

Figure 3: Cumulus castellanus.Thes clouds can sometimes be used by glider pilots. Castellanus (clouds made of very narrow columns) are notorious [17] as being unusable by glider pilots. In order for a cloud to have a usable thermal, the updraft column needs to exist under the cloud, in which case the cloud will have a flat base.
This word refers to an underground room, vault or chamber. It's typically located underneath a church and is used for burial purposes. OK, that's it for hints—I don't want to totally give it ...
