It is a stage of severe thunderstorms and Supercell tornadoes. They are classified as per their appearance and mainly altitudes. Even though Atlanta is not near any major waterways, the resulting flash floods were on a scale seen only with areas near major rivers with wide flood plains. Beyond their fluffy appearance, there is a lot more to know about cumulus clouds -- the most popular clouds of the lot. Some can even become tornadoes given the right conditions. Cumulonimbus incus – Like in the case of cumulonimbus capillatus, the top of the cloud is fibrous but this time also anvil-shaped. These severe storms can often last for 2-4 hours, but are the least common form of thunderstorms, mostly seen in the Great Plains of the United States. Why Are The Sleeping Cycles Of Babies So âMessed Upâ? The weather conditions necessary for such clouds to form include an unstable air mass, sufficient moisture, and an upward force (typically provided by heat). The base of the cloud is often flat, with a very dark wall-like feature hanging underneath, and may only lie a few hundred feet above the Earth's surface. They are formed when warm, moist air rises within the cooler air. Post was not sent - check your email addresses! What Is The Huntsman Spider?

They are also a variation of nimbus or precipitation bearing clouds. They shower us with the necessary rainfall that is one of the most important factors for our sustenance on this planet. The moisture rapidly cools down and condenses to form tiny drops of water, forming the rising cumulus clouds. Cumulonimbus definition is - cumulus cloud having a low base and often spread out in the shape of an anvil extending to great heights. The shelf of the anvil may precede the main cloud's vertical component for many kilometres, and be accompanied by lightning. [10] The average thunderstorm has a 24 km (15 mi) diameter and a height of approximately 12.2 km (40,000 ft). Did you know that there are clouds in the shape of an anvil?

If you’re trying to decide between the two, and the cloud in question has precipitation, lightning, or a fibrous upper portion, you can consider it a cumulonimbus cloud. The atmosphere is a dynamic system, and the local conditions of turbulence, uplift and other parameters give rise to many types of clouds. About one-third of lightning flashes travel from the cloud to the ground; most of these originate in negatively charged regions of the cloud. The layers of Earth's atmosphere, showing heights of characteristic atmospheric phenomena. Have you ever wondered what are nimbus clouds? The downdrafts are due to the falling precipitation. A clearly developed cumulonimbus fibrous-edged top capillatus, Arcus cloud (shelf cloud) leading a thunderstorm, A funnel cloud (tuba) over the Netherlands, Flanking line in front of a strong thunderstorm, An overshooting top is a dome of clouds atop a cumulonimbus, Cumulonimbus calvus against sunlight with rain falling beneath it as a rain shaft (praecipatio), Rain evaporating before reaching the ground (virga), Cumulonimbus storm cells can produce torrential rain of a convective nature (often in the form of a rain shaft) and flash flooding, as well as straight-line winds. Why Is It So Special? In some instances a Thunderhead with enough energy can develop into a supercell which can produce strong winds, flash floods, and a lot of lightning. Occasionally, rising air parcels surpass the equilibrium level (due to momentum) and form an overshooting top culminating at the maximum parcel level. Are Giant Insects Larger Than Humans Possible?

The turbulence created by the friction between air and the surface of the Earth combined with stored heat from the sun helps to drive the majority of weather. This results in the decay or collapse of a thunderstorm or tornado. These types of clouds usually form in tropical areas, where these elements are more commonly found together, but blizzards are another form of precipitation caused by cumulonimbus clouds. Cumulonimbus is rare over the polar regions, and becomes increasingly frequent with decreasing latitude, and is, in fact, an almost regular climax of the diurnal cloud cycle in the humid areas of the tropical regions and in humid and unstable air masses penetrating the temperate latitudes. The direction of the anvil cloud indicates the direction of the movement of tornado.
