The weather service also highlights that lightning “will travel through the wiring and plumbing if your building is struck.” If you are outside when the storm hits, “do not lie on the ground ...
Lightning injuries are divided into direct strikes, side splash, contact injury, and ground current. [1] Ground current occurs when the lightning strikes nearby and travels to the person through the ground. [1] Side splash makes up about a third of cases and occurs when lightning strikes nearby and jumps through the air to the person. [1]
A lightning strike can also create a large Lichtenberg figure in grass surrounding the point struck. These are sometimes found on golf courses or in grassy meadows. [ 12 ] Branching root-shaped " fulgurite " mineral deposits may also be created as sand and soil are fused into glassy tubes by the intense heat of the current.
Global map of lightning frequency--strikes/km 2 /yr. The high lightning areas are on land located in the tropics. Areas with almost no lightning are the Arctic and Antarctic, closely followed by the oceans which have only 0.1 to 1 strikes/km 2 /yr. The map on the right shows that lightning is not distributed evenly around the planet. [5]
Here's another 'shocking' fact: The NOAA reports that about 4-5% of people struck by lightning were talking on a corded phone when it happened. Show comments Advertisement
Plasma temperatures in lightning can approach 28,000 kelvins. Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet ). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit .
A key factor in the ignition of these wildfires is the type of lightning, with long-continuing-current (LCC) lightning being particularly significant. The risk of lightning-ignited wildfires is influenced not only by the occurrence of LCC lightning but also by the availability of dry fuel, which is influenced by how much rain has fallen before.
UVA rays are what can lead to premature aging and can be a cause of skin cancer. “Glass 100% blocks UVB rays — which is what you need to make vitamin D — while allowing in UVA rays,” Dr ...
