How is cumulonimbus clouds formed?
Cumulonimbus clouds are born through convection, often growing from small cumulus clouds over a hot surface. They can also form along cold fronts as a result of forced convection, where milder air is forced to rise over the incoming cold air.
How do cumulonimbus cloud look like?
Since they are so thin, they seldom produce much rain or snow. Sometimes, in the mountains or hills, these clouds appear to be fog. Cumulonimbus clouds grow on hot days when warm, wet air rises very high into the sky. From far away, they look like huge mountains or towers.
Where does a cumulonimbus cloud form?
Cumulonimbus clouds form in the lower part of the troposphere, the layer of the atmosphere closest to the surface of the Earth. This region due to evaporation and the greenhouse effect produces alot of the warm updrafts that make creation of cumulus and cumulonimbus clouds possible.
What do cumulus clouds look like where do they form?
Cumulus clouds are detached, individual, cauliflower-shaped clouds usually spotted in fair weather conditions. The tops of these clouds are mostly brilliant white tufts when lit by the Sun, although their base is usually relatively dark.
What color are cumulonimbus clouds?
They range in color from dark gray to light gray and can appear in rows, patches, or as rounded masses with breaks of clear sky in between.
How does a nimbostratus cloud form?
How do nimbostratus clouds form? Nimbostratus clouds form through the deepening and thickening of an altostratus cloud, often along warm or occluded fronts. These clouds extend through the lower and mid-layers of the troposphere bringing rain to the surface below.
How would you describe a cumulus cloud?
Cumulus clouds are puffy clouds that sometimes look like pieces of floating cotton. The base of each cloud is often flat and may be only 1000 meters (3300 feet) above the ground. These clouds grow upward, and they can develop into a giant cumulonimbus, which is a thunderstorm cloud.
What are 3 facts about cumulonimbus clouds?
Cumulonimbus clouds are large, tall clouds that are dark on the bottom, bring thunderstorms, have a fuzzy outline toward the upper part of the cloud and may have a flat top called an anvil. Besides thunderstorms, these clouds can bring hail, tornadoes and snow, and they also form during hurricanes.
Why do cumulonimbus clouds have flat tops?
An anvil cloud is made of ice particles; these frozen particles form in the highest levels of thunderstorms or cumulonimbus clouds. The cool shape that you see with the flat top is due to rising air in storms. The snow evaporates as it falls through drier air that’s around the upper part of the storm.
What level is a cumulonimbus cloud?
The cumulonimbus base may extend several kilometres across and occupy low to middle altitudes – formed at altitude from approximately 200 to 4,000 m (700 to 10,000 ft). Peaks typically reach to as much as 12,000 m (39,000 ft), with extreme instances as high as 21,000 m (69,000 ft) or more.
