Interesting facts about lightning
Who among us has not seen lightning? I think that every once in my life felt a feeling that excites all the innards, while capturing the look, charming and at the same time causing awe of the power of this phenomenon. Meet! Here is a grand creation of nature - lightning.
Lightning are not only our planet, but also on other planets in our solar system: Venus, Jupiter, Saturn and Uranus, and others.
For physicists Buda useful to know that the lightning current can be from ten to one hundred thousand amperes, and the voltage a million volts, and sometimes up to fifty million volts.
The air in the lightning channel is heated to 30 thousand degrees - is five times larger than the surface temperature of the sun.
The propagation speed of lightning - 1000000 ms. So from the clouds to Earth lightning passes for 0, 002 seconds.
Lightning channel is very narrow. Visible channel has a diameter of about 1 meter and an inner through which current flows - 1 cm. The length of the arc channel can be from 1 to 10 kilometers.
Typical lightning lasts for about 0, 25 seconds and consists of 3-4 digits.
Right now in the world of thunder storms in 1800.
The aircraft lightning strikes on average once every 5-10 thousand flight hours.
The probability of being killed by lightning is 1 to 2 000 000. The same chances for all of us to die from falling off the bed.
Chance to see a fireball at least once in a lifetime is 1 in 10 000.
Roy Sullivan remained alive after seven lightning strikes.
American Major Summerford died after a long illness (the result of a lightning strike the third). Fourth lightning completely destroyed his monument in the cemetery.
The Indians of the Andes lightning strike is considered necessary to achieve the highest levels of shamanic initiation.
Why winter storms are very rare? To form a thundercloud needed updrafts moist air. The concentration of saturated vapor increases with increasing temperature and the maximum summer. The difference in temperature, which determines the rising air, the more, the higher the temperature at the surface of the earth, as at the height of several kilometers, its temperature does not depend on the time of year. So fast riser maximum summer too. Therefore, we and thunderstorms mostly in the summer and in the north, where the cold and in the summer, thunderstorms are rare.
And now some photos of lightning.
The frequency of occurrence of lightning in the world:
From here follow the precautions that must be followed to protect yourself from lightning.
In the house:
Close all windows and doors.
Turn off all electrical appliances from electrical outlets. Do not touch them, as well as the phone during a thunderstorm.
Do not come to the baths, faucets and sinks because metal pipes can conduct electricity.
If you in the house flew into a fireball (although the statistics of these "lucky" very few) do not make any sudden movements, and in any case, do not run away, because you can cause the air flow, in which a bundle of energy fly specifically for you.
Stay away from electrical appliances and wiring, do not touch metal objects and try to leave the scantily atmospheric electrical phenomenon alone. No more than a minute lightning disappear by itself.
Outside:
Try to go into your home or car.
If there is no shelter, move to an open space and bent, push to the ground. It is very dangerous during thunderstorms stand tall! But you can not just go to bed, too! Wet ground is an excellent conductor, so lightning can strike the ground. Try to hide in the lowest place, whether it is a ditch, ravine or a small depression in the ground. In the forest is better to trust in the low bushes.
NEVER stand under a tree standing alone. Lightning primarily directs its action on tall items, including trees. Especially well attract lightning oak, pine, poplar, fir.
Avoid towers, fences, tall trees, telephone and electric wires and bus stops.
Stay away from the bike, barbecues and other metal objects. Do not come to the lake, river or other water bodies. Remove all metal.
In no case do not use an umbrella in a storm!
Do not use a mobile phone.
Do not stand in the crowd.
If you are caught in a storm and the boat to the shore to sail you will not have time, get down to the bottom of the boat, connect the legs and cover your head and ears.
In the car:
If the storm caught you on the road, you must stop, close all windows and the top of the machine (if it is an open top), omit the radio antenna, and most importantly - not to leave this haven. Inside fully enclosed vehicle, you are out of danger during the storm. The fact that, despite the fact that the vehicle consists of a metal, it has the effect of so-called Faraday cage, i.e. a device which is earthed cage made of a highly conductive material. Such a device is well-shields electromagnetic fields.
