JUST INFO ITS NOT YE IPOOD
Rules
There are only 3 rules that electricity follows that one needs to know. Being aware of these rules helps understand lightning (as it is only electricity).
1. Electricity travels-
While this is not technically correct, it is in fact the traveling of electrons that is electricity and this is what causes lightning
2. Electricity travels between earth and another place-
In a lightning strike that is dangerous to humans, the earth is the ground and the other is the cloud.
3. Electricity likes to travel the easiest path between the earth and the other place-
This is why lightning commonly strikes the tallest object. Electricity finds it hard to travel though air (it has low conductivity). Trees, buildings, towers people and other objects conduct electricity much better than air.
Upon these three rules it is easy to create a plan that helps you avoid being struck.
Thunder is nature's warning
By Jack Williams, USATODAY.com
Each year lightning kills 50 to 100 people in the USA, mostly during the spring-summer thunderstorm season.
Anyone who goes outdoors needs to be aware of lightning's danger when thunderstorms are around.
A typical 100-million volt lightning flash can heat the air to more than 40,000°F, which causes it to expand and then contract as it cools. This creates sound waves: thunder. Even if you don't see the lightning, thunder means it's there, perhaps hidden by thick clouds.
For anyone outdoors "thunder is a wake-up call," says Ron Holle, a lightning scientist.
In fact, if you can hear the thunder, the lightning is probably within 10 miles. Thunder rarely travels farther, he notes.
A good lighting safety rule is:
* If you hear it, fear it.
* If you see it, flee it.
This means that if you hear thunder, the lightning is close enough to worry about. While it might be 10 miles away now, it could very quickly come much closer.
If you see a flash of lightning, no matter how far away, it's time to take shelter.
The best shelter from lightning is a permanent building. Sheds or small buildings aren't as safe. Vehicles with metal roofs are also safe, but be sure not to touch any metal surfaces.
It's best to stay away from windows when lightning is close. And lightning has killed people talking on the telephone, taking a bath or near electrical appliances. In rare cases, lightning that hits near a building can follow telephone wires, plumbing or electrical wires inside.
To estimate how far away the lightning is, use the "flash-to-bang" method. If you see a lightning flash, begin counting: "one one thousand, two one thousand, three one thousand," (or however you estimate seconds) until thunder is heard. Since the speed of light is about 186,300 miles per second, lightning is seen the instant it flashes. But sound travels about one mile in five seconds. If you hear the thunder 10 seconds after seeing the lightning, the lightning is about two miles away.
Holle recommends that when the flash-to-bang time is 10 to 15 seconds -- meaning the lightning is two to three miles away -- head for safe shelter, if you're not already there.
If the lighting is closer than three miles, the danger could be very high. A 1988 Florida study found that successive lightning strikes in a storm were two to three miles apart on average. If lightning is three miles away and the storm is moving toward you, the next strike could hit you. The flash-to-bang time can tell you if the storm is approaching. If the time between the flashes and the bangs grows shorter, the storm is getting closer.
Holle says the best defense against lightning is finding out if thunderstorms are forecast before heading outdoors.
If thunderstorms are in the picture, keep an eye out for clouds building into thunderstorms and head for shelter at the first crack of thunder or lightning flash.
