Cirrus clouds can be seen in good weather.Some of their views inform us that a warm sunny day soon badly tarnished.This thread-like white "fibers", which always shine through these celestial bodies like the moon and the sun.They are visible and very bright stars.On a clear day cirrus clouds in any case do not reduce the light.They are located in the top tier of the troposphere.Their height usually ranges from 6 to 12 kilometers.They consist of ice crystals formed by cooling water droplets.Note that precipitation of them fall!
studying an atlas of clouds, scientists have found that they have a direct influence on the climatic conditions of a global nature.Reflecting coming toward them sunlight, they cool the planet, and delaying the outgoing heat, warm it.To date, scientists have not fully explored them, but when it does, the cirrus clouds are an excellent tool for meteorologists.
How are these clouds?
After a long and painstaking work, researchers concluded that the formation of clouds of feathery type is due to the combination of dust and metal particles that make up their base - crystals.What does it mean?The thing is that any cloud (not only a p) consists of small water droplets formed from vapor, which in turn raises the heated air in the sky.Already at the top of the air begins to cool and the steam - condensing.But that whole process could take place, droplets need very small particles, allowing them to stick.In this role and acts as a dust.The scientific name of this "union" - "condensing the grain."Such a discovery - this is the greatest breakthrough in science that studies clouds.By the way, it is believed that the cirrus clouds can be formed through human activity.But that's exactly what?Until it turns out, the version does not find its confirmation.
As fog is formed?
This is very simple.The droplets, which we mentioned above, are condensed almost to the ground.The uniqueness of this phenomenon is that going into the fog, we actually pass through a cloud!At the same time on the clothes, the face and the hands we feel its moisture.By the way, it is easy to explain the formation of the air exhaled by us in the winter time when you exhale it becomes moist and warm, and in contact with the frosty immediately turns into a little hazy clouds.
«relatives»
Very often cirrus clouds combined with their "relatives" - Cirrostratus and Cirrocumulus.They are called "mixed".Cirrostratus remind tonyusenkoy transparent veil, which is often in the background around the moon or sun formed colored rings.This is the result of refracted and reflected rays of light in ice crystals,
of which, strictly speaking, composed themselves cirrus clouds.Cirrocumulus their appearance reminiscent of sheep or fish scales.They can be seen in parallel with cirrus clouds.They are essential to our planet, preventing the lowering of the temperature on the earth's surface.
