DO YOU HAVE YOUR HEAD IN THE CLOUDS? The encyclopedia says that a cloud is an "aggregation of minute particles of water or ice suspended in the air. Clouds form when air containing water vapor is cooled below a critical temperature called the 'dew point'. The resulting moisture condenses into droplets on microscopic dust particles (condensation nuclei) in the atmosphere." Doesn't sound very dream-like, does it? Clouds are neat. This unit does not speak to the colors that clouds take on at sunrise or sunset. It is so wonderful to see lovely pink clouds in the evening. Then you find out that they are pink, not with the flush of romance, but because of volcanic ash in the atmosphere. Like taking the romance out of the moon by getting guys up there to walk on it, clouds are also brought into cold reality by this bit of information. Keep records for a week of the kinds of clouds that you see. You will learn to recognize some of the common cloud types: Cirrus, cumulus, and stratus are the basic types of clouds. Each type of cloud is formed by specific atmospheric conditions, and is, therefore indicative of forthcoming weather. Cirrus clouds are very high in the atmosphere. They usually look feathery and are composed of tiny ice crystals. They are usually a sign of clear weather. Cumulus clouds are lower than cirrus clouds, and airplanes often fly above them. They are vertically developed, usually with a horizontal base and a dome-shaped upper surface. They look like white puffs in the sky and usually indicate fair weather. Stratus clouds are the lowest clouds, and are foglike. They form gray layers across the sky. They are associated with stormy weather. Cumulonimbus clouds, commonly called thunderheads, indicate rain. They are usually very low in the sky and look thick and black. They generally bring rain, snow, sleet, or hail. Cirrostratus clouds are high-altitude layered clouds that often indicate rain or snow. Are clouds the same as fog?  Any problems with this page? Send URL to
