Big puffy white clouds floating through a bright blue summer sky make us smile. But boiling black storm clouds slashed with jagged lightening and crashing thunder make us run for shelter. To be precise, a cloud is nothing more than a collection of water particles or ice crystals floating in the atmosphere.

Clouds are white because their water droplets or ice crystals are large enough to scatter the light of the seven wavelengths (red, orange, yellow, green, blue, indigo, and violet), which combine to produce white light.

The low-altitude clouds are called cumulonimbus, cumulus, stratus, stratocumulus, and nimbostratus. CUMULONIMBUS clouds are piled up high like scoops of dark ice cream. These clouds usually bring rain showers. STRATOCUMULUS clouds are spread out heaps of dense cover that rise higher in the atmosphere.

Fair Weather Cumulus Clouds puffy cotton balls floating in the sky. Fair weather cumulus have the appearance of floating cotton and have a lifetime of 5-40 minutes. Known for their flat bases and distinct outlines, fair weather cumulus exhibit only slight vertical growth, with the cloud tops designating the limit of the rising air.

Your new love of Latin will come in handy as you decode the names below! Cumulus are the puffy, white, cotton-top clouds that look so soft that you picture angels lounging around and doing their thing on them. They are considered low-level clouds (below 6500ft), but some forms can build up past 20,000ft.

Cumulus Clouds Cumulus clouds are white, puffy clouds that look like pieces of floating cotton. Cumulus clouds are often called fair-weather clouds. The base of each cloud is flat and the top of each cloud has rounded towers. When the top of the cumulus clouds resemble the head of a cauliflower, it is called cumulus congestus or towering cumulus. These clouds grow upward and they can develop into giant cumulonimbus clouds, which are thunderstorm clouds.

HIGH. Clouds forming in high altitudes are called cirrus, cirrostratus, and cirrocumulus. It is so cold in the upper atmosphere that high altitude clouds contain ice crystals instead of water particles. CIRRUS clouds form when the wind blows these ice crystals into wispy streaks that look like thin horse tails.
