Almost all people are afraid of a thunderstorm or, in any case, are afraid of it and prefer to wait in the safe place - and it is the correct approach. The sky darkens and drags on, the sun vanishes, but the thunder rattles and the lightning sparkles – the nature rages, and it can be dangerous.

Thunderstorm – the natural phenomenon which of one name a lot of things are already clear. When everything lights up with the flashes accompanied with peals of thunder which the heavy rain, as a rule, follows inevitably around there are questions: ""What occurs there?" ", " "From where the lightning and why it so brightly sparkles undertakes?"". Lightning nature electric. Thunderclouds are the real giants. They and from the earth seem huge, but from there nevertheless is not clear as far as they are big. Height of a storm cloud of the average sizes is several kilometers. Inside they at all not such quiet as can seem outside. Air flows in clouds chaotically move extensively, all there "rages and boils". Temperature in a cloud is distributed at all not evenly too. On its top it is usually very cold, about-40 degrees Celsius. Water which is the main component of a storm cloud at such temperature, of course, freezes. Small pieces of ice which rush in a cloud as well as usual drops of water are formed: with a huge speed and very randomly. Small pieces of ice constantly face with each other and water, they are loaded with electricity and collapse. The heaviest move closer to the lower part of a cloud and there usually thaw, sometimes drop out in the form of a hail. Pretty fast opposite electric charges in a cloud concentrate in different areas: above prevail positive, and below negative, but swirling does not stop inside. Sometimes there are powerful streams when the set of positive and negative particles faces at the same time. Storm clouds are very large formations and when two powerful whirlwinds loaded opposite face, very strong electric discharge is formed. It is also a lightning. It it is dazzling sparkles, instantly heating air around itself to very high temperature so that he explodes. The thunder is and there is this explosion of the air mass heated by electric discharge. Electric discharge can have the direction or from one part of a cloud to another, or from them to the earth. If the lightning hits into the objects located on the earth, then it without effort splits even big stones, and everything that burns, from its blow ignites. The lightning is attracted to everything that towers over other landscape. Therefore to protect houses, people constructed lightning rods: these are metal poles which take away current to the earth and in such a way neutralize it. But if the thunderstorm, and you began not houses, then do not hide under high objects, for example, under trees. Because probability is high that the lightning will strike in one of them.
