There is lightning in my area is it possible it can struck my house?

Answer 1

Here is an excerpt from the National Severe Storm Laboratory website ( http://www.nssl.noaa.gov/primer/lightnin... ):

The creation of lightning is a complicated process. We generally know what conditions are needed to produce lightning, but there is still debate about exactly how lighting forms.The exact way a cloud builds up the electrical charges that lead to lightning is not completely understood. Precipitation and convection theories both attempt to explain the electrical structure within clouds. Precipitation theorists suppose that different size raindrops, hail, and graupel get their positive or negative charge as they collide, with heavier particles carrying negative charge to the cloud bottom. Convection theorists believe that updrafts transport positive charges near the ground upward through the cloud while downdrafts carry negative charges downward. What follows is a summary of what we know.

Thunderstorms have very turbulent environments - strong updrafts and downdrafts occur often and close together. The updrafts carry small liquid water droplets from the lower regions of the storm to heights between 35,000 and 70,000 feet - miles above the freezing level. At the same time, downdrafts are transporting hail and ice from the frozen upper parts of the storm. When these particles collide, the water droplets freeze and release heat. This heat keeps the surface of the hail and ice slightly warmer than its surrounding environment, and a soft hail, or graupel forms.

When this graupel collides with additional water droplets and ice particles, a key process occurs involving electrical charge: negatively charged electrons are sheared off the rising particles and collect on the falling particles. The result is a storm cloud that is negatively charged at its base, and positively charged at the top.

Opposite charges attract one another. As the positive and negative areas grow more distinct within the cloud, an electric field is created between the oppositely-charged thunderstorm base and its top. The farther apart these regions are, the stronger the field and the stronger the attraction between the charges. But we cannot forget that the atmosphere is a very good insulator that inhibits electric flow. So, a HUGE amount of charge has to build up before the strength of the electric field overpowers the atmosphere's insulating properties. A current of electricity forces a path through the air until it encounters something that makes a good connection. The current is discharged as a stroke of lightning.

While all this is happening inside the storm, beneath the storm, positive charge begins to pool within the surface of the earth. This positive charge will shadow the storm wherever it goes, and is responsible for cloud-to-ground lightning. However, the electric field within the storm is much stronger than the one between the storm base and the earth 's surface, so about 75-80% of lighting occurs within the storm cloud.

Basically, you should unplug any appliances around your house as the electricity from a lightning bolt hitting your house will travel through the wiring and potentially electrocute you if you were using one of these appliances. Lightning may never hit you directly if you are indoors.

Answer 2

If your building is shorter than the buildings of your area then the chances of affecting by lightening is rare.But if your building is taller than other buildings of your area still you can be safe by providing lightening arrester on the roof top of your building.

Answer 3

Yeah unplug your computer.

Answer 4

Yes it is possible. Also, just before a lightning bolt strikes the ground, several "fingers" of lightning also reach out of the ground to try to connect with the bolt which is descending from the cloud. So there are lighning bolts which go from cloud to earth and vice-versa. Scary hey ?

Answer 5

If you are inside your home, there are a number of activities you should avoid. If lightning strikes your home, it takes the easiest route to earth, such as wires, cables and water pipes. Using a telephone, watching television and using a pc can all increase your risk of being affected by a strike to your home.

Answer 6

yaah ,but u have to use a special tool to be safe ,simply it is a pin rod linked towards earth ,in order to evacuate electic charges which may struck ur house
