What are cumulonimbus clouds?

Lower levels of cumulonimbus clouds consist mostly of water droplets while at higher elevations, where temperatures are well below 0 degrees Celsius, ice crystals dominate. read more

Towering cumulonimbus clouds are typically accompanied by smaller cumulus clouds. The cumulonimbus base may extend several miles across and occupy low to middle altitudes - formed at altitude from approximately 200 to 4,000 m (700 to 10,000 ft). read more

Cumulonimbus clouds are a perfect example of how difference in altitude can affect the formation of clouds. Cumulonimbus clouds form in the lower part of the troposphere, the layer of the atmosphere closest to the surface of the Earth. read more

Cumulonimbus clouds are composed оf liquid droplets closer tо ground level, anԁ ice crystals high up іn thе upper regions. The cloud іѕ characterized by great thermal currents wіth the moist air inside racing upwards аt 100 mph (ten times thе speed оf а normal cumulus). read more
