In fact, the insurance industry estimates that around 6.5% of all property and casualty claims are related to lightning strikes. Do lightning storms cause electrical damage?Īlthough lightning storms can be a sight to behold, they can also cause electrical damage to your home or business. Because opposites attract, the stepped leader and the negative charge at the ground reach towards each other and quickly meet. As it nears the ground, it induces enormous quantities of positive charge in the earth, especially at the tips of tall objects. The stepped leader carries tons of negative charge. This begs the inquiry “Does Lightning travel up or down?” It’s plasma resulting from air being ionized and superheated by an electric charge jumping between cloud and ground or two clouds. Heat is the random movement of molecules and travels from hot to cold in all directions. Why does Lightning want to go in the ground? Objects on the ground generally have a positive charge under a typical thunderstorm. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts. Cloud-to-ground (CG) lightning comes from the sky down, but the part you see comes from the ground up. You might be asking “Where does Lightning come from the ground?” Help Others: If other people are stranded or stuck outdoors, take them in and help them. Staying safe indoors : Do not touch any electrical appliances or switches with wet hands, and preferably keep the heavy appliances switched off. You can follow the following steps to protect yourself and others during a storm: Do not stay outdoors when a thunderstorm has started. Why does Lightning need to touch the ground? It actually does come from ground up typically a lightning stroke is caused by a step leader that breaks down the insulation of the air, when it reaches the ground the brilliant flash you see is the lightning discharge returning from the ground to its source although in rare cases you can have cloud to ground lightning. This creates a dangerous and potentially deadly ground current near the lightning strike. When lightning strikes the ground or an object on the ground, the discharge occurs in and along the ground surface (not deep into the ground). What happens when lightning strikes the ground? In reality, lightning can and will strike the same place twice, whether it be during the same storm or even centuries later. So after lightning strikes one place, it’s probably safe from another strike. The lightning on the ground is seen in the case of cloud to ground lightning.Ī common query we ran across in our research was “Does Lightning really not strike twice?”. In reality, there are three main kinds of lightning in nature, which are distinguishable on the basis of where they occur. No, lightning does not always strike the ground. Earth is not a perfect conductor – it has resistance and may be considered as infinitely large resistor. As it travels through the mass of the earth, it generates voltage that is proportional to the resistance of the earth mass. The current from the lightning pulse / ground fault spreads radially outwards from the point of entry into the earth.
