Each of us watched the clouds, to see how they suddenly appear in the sky and then how to swim, changing its shape: it is a dog, the fish, the castle with turrets, the caravan of camels.So, let's understand what are the clouds.
different, but at the same time, these same
cumulus clouds.Metamorphosis is happening with them.This snow-white clouds that grow right before your eyes.They are called "messengers of the good weather."But it is good?Of course not!They, as well as any other, and are the showers and rain, but the truth, kratkovremennye.Peristye clouds - faithful heralds of rain.If you saw them, then wait two days of rain.They are thin and translucent, resembling the appearance of feathers.Sun and Moon shines through them.In their place come the other clouds that descend lower and lower ... They are layered and rain, clouds filled with water very much.In mountainous areas they sink so low that everything is immersed in a ghostly fog. "Lentil".Some clouds are so unusual shape that are easily mistaken for UFOs.Only here do not fly this "object".It is absolutely calm, motionless clouds.Even the wind does not make them budge!Their other name - "torpedo".I think it is not necessary to explain that their so-called because of the striking resemblance to the shape of a torpedo, dolphin or any other elongated object streamlined formy.Zachastuyu over the mountains you can see the cloud "waving flag".This happens due to the air, careening over the top, covered with snow, which is then cooled and condensed.Water vapor, which is in the air begins to thicken into a cloud like the flag, through which air flows.If you stand under the "flag", you will experience a certain feeling ...
talking about what are the clouds, it should be noted that the "lentils" and "waving flags" - is an indisputable sign of deteriorating weather."Torpedo" is - an invasion of "alien" the air, accompanied by hurricanes, rain, blizzards and heavy snow!
All is not gold that glitters ...
unique natural phenomenon - a cloud with a silver sheen.Enjoy them on the photo.Cloud was first observed by the famous St. Petersburg astronomer Tserarsky in the XIX century.Science for a long time could not determine what kind of "fruit" are, and what are the clouds of this species yet.Only when it became possible for them to monitor from space, more clear.It is proved that they are due to fine particles from the Earth and micrometeorites, flew from space.All of this serves as condensation nuclei for water, which rises high above planetoy.Kstati, there are other opinions on what the clouds are silver.For example, some scientists say that they can be formed by particles of volcanic dust.This version has a life after the most powerful volcanic eruption of Krakatoa.Other scholars say that it is very fine particles of meteoritic material which invaded the atmosphere of our planet.In favor of this theory is the fact that after the fall of the so-called Tunguska meteorite in different parts of the world could enjoy the bright silver clouds.
