First we need to know how cumulonimbus clouds in general form. Cumulonimbus clouds develop when the atmosphere is unstable. Generally, air temperature drops with increasing altitude, and warm air tents to rise through cold air. But, when air is made to rise it decompresses and cools. Under most conditions this air will soon become cooler than the surrounding air and sink back down. In this situation the atmosphere is said to be stable. If, however, the rising mass of air remains warmer than the surrounding air it will continue to rise on its own buoyancy and the atmosphere is said to be unstable. In the case of a cumulonimbus cloud this instability is provided by moisture. Water vapor holds a lot of energy in the form of latent heat. As a rising moist air mass cools the moisture in it condenses into clouds and rain, releasing its latent heat. The energy release dramatically slows the rate at which the rising air cools, so it remains warmer for longer. If there is enough heat and moisture, and the atmosphere is unstable enough the rising air mass will form a cumulonimbus cloud. Eventually the rising air mass will reach the same temperature as its surroundings and stop rising, forming the distinct flat top of a cumulonimbus. More latent heat and a colder upper atmosphere lead to taller cumulonimbus cloud. Since the height a cumulonimbus is an indicator of the degree of instability, the tallest thunderstorms are usually the strongest.
No. Cumulonimbus clouds have flat bottoms and tops, but are very tall.
There is no such thing as a cumulonimbus tornado. A cumulonimbus cloud is a ver large towering cloud. Most thunderstorms are cumulonimbus clouds, and some of the strongest of these storms are what produce tornadoes.
Cumulonimbus clouds.
The thickest kind of cloud is a cumulonimbus cloud. These clouds are tall and dense, often associated with thunderstorms and severe weather. They can extend vertically for several miles in the atmosphere.
Cumulonimbus.
Cumulonimbus clouds have a large and tall horizontal appearance. They are capable of producing severe weather conditions such as thunderstorms and hailstones.
They are called cumulonimbus clouds.
Cumulonimbus clouds are tall, towering clouds that can be found in the sky at various locations around the world. They are associated with thunderstorms and can form in regions where there is high humidity and instability in the atmosphere.
Cumulonimbus.
A cumulonimbus cloud is a towering cloud that is often associated with thunderstorms. It is characterized by its large vertical development, extending high into the atmosphere, and can produce heavy rain, lightning, thunder, and sometimes even tornadoes. Cumulonimbus clouds have a characteristic anvil shape at the top due to strong upper-level winds.
Cumulonimbus is the largest type of cloud. It is the only cloud that is tall enough to occupy low, medium and high heights. It is also the only (weather related) cloud that can form hail and lightning. Lightning can also be created in volcanic ash clouds, but they are not a weather related cloud.
