What is cloud and what are they people

Fluffy Belogrivov horses or dark storm clouds, light smeared or blurred bright scarlet beauty at sunset.What is the cloud for meteorologists, air traffic controllers and the romantic poets?Maybe for us it is something more than just water vapor.Air cushions White sung in many songs and poems.The pilots and skydivers seek to take a look on top of the boundless beauty of cotton masses.They called the new inventions (such as the Internet space), soft beds, bring in cookbooks (as a description of the air cakes and other desserts) and dream interpretation (clouds dream would reveal the level of spiritual harmony of man).

As you can see, it is quite capacious concept and word.How children respond to the question, what is the cloud?Firstly, I must say that it is a very light airy education.Indeed, in many cartoons funny characters jump, ride, walk on them.Say it is a collection of droplets of evaporated water, hot air, so to speak fog, only much higher above the ground.They are, unfortunately, can not touch, but you can admire the infinite.

We see a very beautiful white clouds when their density is very small, which allows the sun's rays pass through the fluff.If we have accumulated over the dark (blue or gray) lumps, it means that the concentration of water droplets does not allow light to get through.These fine particles of liquid can be attached as a speck of dust and soot, staining the clouds that we see even more gloomy and ominous color.

geography lessons we have learned that a large amount of types of clouds.They vary depending on the type of the ground, the height of their location, the danger that they can be expected.The three main types - cirrus, stratus and cumulus - formed all other intermediates.

What is the first type of clouds and what they consist of?We can see them in clear weather high up in the sky like a smeared white paint.Their movement is not noticeable to the naked eye.Such clouds are composed mainly not from drops and crystals from the water, as at a height where they are located (fourteen kilometers), very cold.

layered clusters much steam at the expected change in the weather.On land they white-gray in color and usually fly high "by" immediately, promising or cooling rains.

Cumulus clouds - this is the most close to us education.They may already be located on four hundred meters above the ground.Typically, these "cotton wads" float across the sky in good weather, reminding us of different animals, household items or even familiar people.Who would have thought: The last type of water clusters can be very dangerous during takeoff or landing of the aircraft, as it significantly impairs the visibility of the pilot ...

In general, what the clouds for an air traffic controller or aviator?This is an important indicator of the present and future weather during the flight, lifting up and landing.Type, number and height allow the judge waiting for the pilot and passengers of turbulence and thunderstorms, and even found time to avoid problems in flight.A special devices help professionals determine the water content of clouds (that is, the density of the water droplets in them) and, accordingly, make the right decisions about the movement in the air iron birds.
