How Are Clouds Formed?

Various Forms of Clouds

Various Forms of Clouds

When the sky is clear, we could see clouds in the sky. The clouds looked like white cottons flying in the sky. When the sky is clear, the clouds will look so white. Often we see the white clouds of various shapes. Sometimes lumpy, sometimes spread and thin, sometimes it shaped like fish scales, or striped like fiber. Briefly seen clotted, soon changed their shape, scattered brought by the wind.

Indeed, the shape of the clouds are always changing following the weather conditions. Often beautifully shaped cloud in the sky like a painting. Take a look at the top of a high mountain, you will see the clouds which cover the mountain. Truly beautiful isn’t it? That is one of the power of the God who created the heavens and the earth with its contents. Then, roughly how are clouds formed?

Starting from the rainfall, and there is the sunlight that reach the earth’s surface, then sunlight is absorbed by the earth, plants, soil, rivers, lakes and the sea, causing the water to evaporate. Water vapor rises into the air or atmosphere. Water vapor rises higher and higher because the air pressure near the Earth’s surface is greater than in the upper atmosphere. Getting to the top, the atmospheric temperature is also getting cooler, the water vapor will condense on the dust of the atmosphere, forming water droplets which are very finely sized 2-100 mm (1 mm = 1 / 1,000,000 meter). Without the presence of atmospheric dust, called aerosols, condensation does not easily occur. Billions of water droplets are then assembled to form clouds.

Forms of Clouds

Various cloud forms depending on weather conditions and their altitude. But the main forms can be grouped into three types, namely, the form of which is layered in Latin called stratus, which forms fibrous called cirrus, and lumpy called cumulus.

In areas of low elevation (less than 3,000 m) which is the lowest, stratus clouds cover the top of mountain that are not too high. In the lower area of ​​the center, shaped strato-cumulus clouds, and near an altitude of 3,000 m cumulus clouds form. Big and thick cloud in the lower area called cumulo-nimbus which potentially be rain, and causes thunder and lightning.

Clouds at medium altitude can be formed on the mountain height of over 3,000 m, forming an umbrella over the top of mountain. For example at the top of Mount Fuji, Japan (3,776 m), it’s peak is always filled with brilliant white snow which are very beautiful. At the height of this medium can be formed alto-stratus clouds are in rows, alto cumulus and alto-Sirus.

What about the clouds in the higher area (above 6000 m)? There is formed siro-stratus clouds that appear as cassia around the sun or moon. Also formed siro-cumulus cloud shaped pieces into pieces spread out wide. Cyrus also can form thin clouds scattered like smoke.
