A fascinating occupation to look into the sky for floating clouds in the form of figures, feathers, feline tails. Sometimes they become a source of rain, snow or fall on the ground in the form of a thick fog. Let's try to understand nature and the reason for the appearance of this atmospheric phenomenon.
Where do clouds come from
The man was able to touch his hand to the cloud with the advent of the balloon. Rising high in the sky, the brave airflofers were in captivity of the fog. They were not mistaken, the cloud is nothing but the smallest droplets of water or ice crystals resulting from the condensation of water vapor. Water particles are so small that can be maintained in the atmospheric layers with a slight movement of ascending air masses.
When the surface of our planet, consisting of 71% of water, is heated by the sun, evaporation and invisible water vapor, stirring with warm air flows, rises into the troposphere. Reaching the dew point, it becomes possible to condensate water vapors in the cloud due to:
- lowering the air temperature during its ascent
- increase of absolute humidity
Warm air flows rise at a certain height (condensation level), water vapor becomes a cloud that grows and can reach 10 km in diameter - the flight height of the passenger aircraft. There is a point on which the cloud stops its growth - this limit is called the level of free convection. If absolute moisture inside the cloud reaches a critical value, water drops stick together and, reaching a certain mass, falls out to the ground, overcoming uplink air flows.
What are the clouds
The clouds are characterized by a height of location from the ground surface, distributed by scientists on certain tiers and are systematized by the variety of forms:
- pirish
- kuchny
- silver
- over cider
- kuchevo-rain
- layered, etc.
Not from each cloud falls on the ground the rain and snow, and from the heap-rain, layered-cumulus, layered and rain. It is in them a favorable conditions for sticking water particles in drops or crystals. They shed their lively moisture on the forests, fields, gardens and gardens or cover their snow sauna ..
The clouds are formed above the surface of our planet as a result of evaporation, transferred to significant distances, fall out in the form of precipitation and fall into the soil, lakes, rivers, sea again. So closes the whirlpool of water in nature. Unfortunately, the distribution of moisture occurs unevenly and where it is missing, fires arise, representatives of the flora and fauna of our planet die.
Millions of years of clouds are involved in a vital process - the cycle of water in nature. And creative people - poets and artists, the clouds are inspired to create their lyrical works. The sky would be boring, if once waking up, we did not see beautiful, funny and breathtaking atmospheric formations - clouds.
