	Cumulus cloud - Wikipedia, the free encyclopedia
		A cumulus cloud (Cu) is a cloud belonging to a class characterized by dense individual elements in the form of puffs, mounds or towers, with flat bases and tops that often resemble cauliflower.
		Though most common in warm, summer weather, cumulus clouds can be formed at any time of year.
		Cumulus clouds often form in anti-cyclonic weather but sometimes the descending air in the anticyclone produces an inversion layer which prevents the air rising to a height where its moisture can condense.

	AMS Glossary
		Cumulus are driven by thermal convection and typically have vertical velocities in excess of 1 meter per second.
		Cumulus congestus is the result of the development of cumulus mediocris and, sometimes, of that of altocumulus castellanus or stratocumulus castellanus.
		Cumulus congestus often transforms into cumulonimbus; this transformation is revealed by the smooth, fibrous, or striated aspect assumed by its upper portion.

	Reference.com/Encyclopedia/Cumulus congestus
		Cumulus congestus clouds are characteristic of unstable areas of the atmosphere which are undergoing convection.
		Because Cumulus congestus is produced by strong updrafts, it is typically taller than it is wide, and cloud tops can reach 5 000 metres (15 000 feet).
		Cumulus congestus will mature into Cumulus calvus under conditions of sufficient instability.

		Cumulus Humilis is the smallest arrangement of cumulus cloud (Humilis meaning humble in Latin) and can in some cases be an indication that worsening weather conditions may occur.
		Cumulus Congestus needs strong updrafts to assist in its development, and the resulting cloud tops can often rise to an altitude of 15 to 20 thousand feet, making Cumulus Congestus much taller than it is wide.
		Pyrocumulus is a dense cumulus cloud that is primarily caused by forest fires.

		When cumulus start growing vertically and the tops look like cauliflower, then they are called cumulus congestus.
		When the tops of cumulus congestus flatten out and become wispy, they are called cumulonimbus or thunderstorms.
		Cumulus are composed of water droplets, except the wispy tops which are ice crystals.

		Cumulus clouds form as water vapor condenses in strong, upward air currents above the earth's surface.
		Cumulus clouds are usually very isolated with large areas of blue sky in between the clouds.
		However, when the atmosphere becomes unstable and very strong, upward air currents form, cumulus clouds can grow into cumulus congestus, or towering cumulus.

	Clouds with vertical development (Site not responding. Last check: 2007-10-09)
		Cumulus and Cumulonimbus clouds are clouds which have significant height as well as horizontal dimension.
		Cumulus clouds are puffy, cottonlike white clouds which contain a flat base, rounded towerlike tops and a sharply defined outline against the sky.
		The clouds in the background may be cumulus congestus, although it is difficult to tell because they are on the horizon where spacing between individual clouds is difficult to observe.

	Cumulus congestus
		Typical cumulus spreading somewhat to the sides when conditions are stable, that is in a high-pressure weather-area suppressing vertical movements.
		One might wonder where the change from congestus to calvus is. Well, this cloud formation could be either.
		This is not a typical example of a congestus cloud but looks more like a mystery cloud with its colours and strange form in the evening light.

	12B.2 Factors responsible for the vertical development of tropical oceanic cumulus convection (2004 - 26HURR) (Site not responding. Last check: 2007-10-09)
		Recent studies on tropical cumulus convection have been focusing on the various modes of cumulus clouds: not only shallow trade wind cumulus and deep cumulonimbus, but also cumulus congestus.
		In the DRY1 period the most prominent cumulus mode is shallow cumulus, while in the other two periods three modes of cumulus clouds constitute the population of tropical cumulus clouds.
		As moist layers becomes above the 3-km level the development of cumulus convection that has a congestus or cumulonimbus character is simulated; and further increasing the depth of the moist layer results in prevalent deep convection and the existence of the three mode of cumulus convection.

	CONVECTIVE CLOUDS
		Cumulus congestus often release abundant precipitation in the form of showers.
		In this case, the character of the precipitation may help to distinguish cumulonimbus, which produces a showery type and is often accompanied by lightning and thunder, from nimbostratus, which produces a steady, continuous precipitation.
		The cloud should be called 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.

		Fair weather cumulus clouds have a height that is similar to its width.
		Cumulus congestus or towering cumulus have a vertical depth that is greater than their width.
		When cumulus congestus form in the morning it is a good indicator that storms may form later in the day.

		While it looks like a sculpted cumulus the whole cloud was actually a standing wave lenticular and it formed and vanished and reformed over a period of minutes always in the same place over Trowbridge.
		This particular congestus mediocris has a clean, flat base showing that it is a powerful thermal and would make for good flying.
		Congestus are the largest cumulus we should really thermal near as the next stage is Cumulonimbus.

		Cumulus is the name given to cloud that develops from vertical upcurrent of air - it is characterised by vertical rather than horizontal development.
		As cumulus grows, it may develop into a mass of spreading 'upwardly mobile' sproutings of cloud from a large base - cumulus congestus.

		Cumulus humulus clouds are fair weather cumulus and can usually be found on sunny summer days.

		In this case above the cumulus clouds is a high level veil of cirrostratus (which gives the sky a milky appearance), and a mid level stratus cloud (top left).
		On both occasions, the cumulus clouds were developing in cool polar maritime air, on a WNW wind, following the passage of a cold front.
		Cumulus clouds can produce some of the most dramatic 'cloudscapes', often causing a marked contrast between light and shade.

		This paper is the second in a three-part series in which a three-dimensional numerical cloud model is used to simulate cumulus congestus clouds at high resolution in an effort to better understand the mchanisms associated with entraiment and detrainment.
		A model for shallow cumulus convection is formulated in which the vertical momentum equation and horizontal divergence equation are combined to produce a diagnostic equation for the perturbation pressure field.
		With use of the model of the steady-state entraining cumulus draft, it is possible to describe the formation and structure of the downdraft observed at the down-shear edge of an oceanic trade-cumulus cloud.

		The goal of the comparison is to evaluate the nadir-view pixel cloud optical depth retrievals derived using plane-parallel radiative transfer theory, and the assumptions for vertically distributing the optical depth.

	CONVECTIVE CLOUDS
		Cumulus mediocris clouds are of moderate vertical extent, with small protuberances and sproutings at their tops.
		If a cumulus congestus cloud resembles a narrow, very high tower, it often is called a towering cumulus, although a more proper designation would be cumulus castellanus.
		Certain cumulonimbus clouds appear identical to cumulus congestus.

		Cumulus congestus clouds, with moderate shortwave albedos and cloud-top temperatures near freezing, occur fairly often in the tropics.
		For the cumulus congestus cases the entrainment rates are approximately constant for cloud-top hegths up to the mid-troposphere, then decreasing entrainment rates are required to get higher cloud-tops.

		There was some bubbling cumulus congestus to the east over the Dandenong ranges, but this was the best shot that came out.
		There is a layer of pileus in front of the cumulus in the middle of the shot.
