A collection of visible vapor, or watery particles, suspended in the upper atmosphere.
A mass or volume of smoke, or flying dust, resembling vapor.
dense concentrations of suspended water or ice particles
A visible aggregate of minute water droplets or ice particles in the atmosphere above the Earth's surface.
When water vapour in the air condenses as a mass of air rises and cools, clouds are formed. Clouds consist of water droplets and ice crystals. Cloud cover is usually measured in eighths. eg 4/8ths is half the sky covered in cloud.
a visible mass of fine water droplets or ice particles floating in the air.
1. A visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes ranging up to several miles above sea level. 2. A mass, as of dust, smoke, or steam, suspended in the atmosphere or in outer space. Every atmospheric cloud (e.g. not dust kicked up by the wind) is made up of water droplets and/or ice crystals.
Mass of water droplets or ice crystals caused by water vapor in the atmosphere condensing or freezing. See Fig. 1 below for an animation and explanation of how clouds form over mountains. Fig. 1 As air flows against and over a mountain range, it cools as it rises. The water vapour in the rising air condenses into droplets and forms clouds. When the droplets are large enough they may fall as rain. Most clouds are formed by the ascent and consequent cooling of air to the point of saturation. When the air is saturated, further cooling results in the appearance of liquid water particles and/or tiny ice crystals. See the Clouds page for more detail and the four ways in which moist air can be lifted to form clouds. To top

Visible water vapor suspended in the air
A form of condensation. A concentration of water droplets or ice crystals, suspended in the atmosphere.
In acoustical industry terms, an acoustical panel suspended in a horizontal position from ceiling/roof structure. Similar to a baffle but in a horizontal position.
A visible mass of condensed water vapor particles or ice suspended above the Earth's surface. Clouds may be classified by their visual appearance, height, or form. Source: EPO.
A visible collection of very fine water droplets or ice crystals suspended in the atmosphere at altitudes from just above the ground to several miles above sea level.
A visible collection of minute particle matter, such as water droplets and/or ice crystals, in the free air. A cloud forms in the atmosphere as a result of condensation of water vapor. Condensation nuclei, such as in smoke or dust particles, form a surface upon which water vapor can condense.
The visible conglomeration of water droplets that occurs above ground level. They typically form as a result of moisture-laden air that is rising and cooling, causing its moisture to condense around solid airborne nuclei. There are many types of clouds, depending upon how they are formed and their appearance.

a visible mass of minute water and/or ice particles in the atmosphere suspended above the earth's surface
is a visible mass of condensed water vapor (liquid or ice) particles.
A mass of tiny droplets of water that condensed from the air. A dark cloud blocked the sunlight.
A visible cluster of tiny water and/or ice particles in the atmosphere above the earth's surface.
A hydrometeor consisting of minute particles of liquid water or ice, or both, suspended in the free air and usually not touching the ground. It may also include large particles of liquid water or ice and non-aqueous liquid or solid particles such as those present in fumes, smoke, and dust.
Condensed water vapor floating in air. They can take many different shapes due to wind patterns and moisture content. They play an important part in the world's weather because of the water they bring and because of their radiative properties vis a vis global warming.

A collection of tiny particles of liquid or solid water occurring above the Earth's surface. Clouds are classified accord to their height of occurrence and shape. The major types of clouds include: Cirrus, Cirrocumulus, Cirrostratus, Altocumulus, Altostratus, Nimbostratus, Stratocumulus, Stratus, Cumulus, and Cumulonimbus.
A structure formed in the lower atmosphere by condensed water vapour and ice particles.
A cloud is a visible mass of condensed droplets or frozen crystals suspended in the atmosphere above the surface of the Earth or another planetary body. The branch of meteorology in which clouds are studied is nephology.
