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 clouds are a genus of free-convective low-level cloud along with the related limited-convective cloud stratocumulus. These clouds form from ground level to 2,000 metres (6,600 ft) at all latitudes.
Cumulonimbus clouds are large, fluffy, and mighty clouds that take the shape of an anvil or a huge mushroom at the top when well-developed. They are very dense clouds that soar up to a height of about 15 – 22 km. The anvil or mushroom shape is caused due to the strong wind shear or warm air turbulence when the cloud reaches the troposphere.
Jun 2, 2024 · Cumulonimbus clouds are composed of water vapor near the bottom and ice crystals near the very top, part of the reason why their growth typically has a cap before the storm finally breaks. They are often called thunderheads or storm clouds—even if they don’t produce precipitation, e.g., dry storms—because they are often dark and ominous.
Towering cumulonimbus clouds rise thousands of metres, producing violent thunderstorms and releasing latent heat in the surrounding air. As a result, the upper tropospheric warm belt migrates northwestward from the ocean to the land.
Cumulonimbus clouds are menacing looking multi-level clouds, extending high into the sky in towers or plumes. More commonly known as thunderclouds, cumulonimbus is the only cloud type that can...
Apr 12, 2023 · Cumulonimbus clouds are the largest cloud formations, sometimes breaking through into the stratosphere. Cumulonimbus flammagenitus cloud (CbFg) is also known as the pyrocumulonimbus cloud. This rare type of Cb forms above a massive heat source, like a wildfire.
This striking photograph shows the developing phase of a summer thunderstorm in New Jersey, USA. Note the very dark appearance of the base of the cloud, which is an indication of a very thick developing cumulus cloud. Also note the vivid interplay of sunlight at the cloud edges.
Certain Cumulonimbus clouds appear nearly identical with Cumulus congestus. The cloud is identified as Cumulonimbus as soon as at least a part of its upper portion loses the sharpness of its outlines or presents a fibrous or striated texture.
Feb 3, 2010 · Heavy and dense cloud, with a considerable vertical extent, in the form of a mountain or huge towers. At least part of its upper portion is usually smooth, or fibrous or striated, and nearly always flattened; this part often spreads out in the shape of an anvil or vast plume.
