A lightning strike happens when two clouds interact with each other, causing an imbalance that is manifested as an electrical discharge. however lightning bolts last for a few milli-seconds so the amount produced (if at all) would be very insignificant and possibly even non-measureable. Have you ever wondered what happens when lightning strikes the sea? Left: A lightning bolt strikes the Atlantic Ocean near Florida. These severe injuries are not usually caused by thermal burns since the current is too brief to greatly heat up tissues; instead, nerves and muscles may be directly damaged by the high voltage producing holes in their cell membranes, a process called … (Sault Ste. $\endgroup$ – user10851 Dec 19 '14 at 19:33 add a comment | 2 Lightning does not penetrate deep into water, but the charge disperses in all directions, favoring the surface.

It pierces the ground, splintering as it lances the sand. Stronger lightning strikes and thinner beds of sand make for larger ones. Lightning strikes strike near water because water is a good conductor of electricity. “Basically lightning stays more on the surface of the water rather than penetrating it. if you think of electrode 1 as the ligthning and electrode 2 as the ground then seemingly it would happen. A reader brought to my attention a question that is floating around the internet. Apparently the surface water does not heat up enough to cause the positive charge needed for lightning to occur. share. Favorite Answer. In an instant, no more than one second, the white-hot thunderbolt melts and fuses the sand around it and creates an object, a rock, a hardened mass of matter in the shape that the lightning took when it entered the earth. Image courtesy NOAA. How far the charge travels depends on the intensity of the lightning, topography of the water, salinity and temperature. Would the electricity just fizzle out after a certain distance or would it keep traveling until it hit an insulator? Search Search. report. The electric current has to pass through your body to do you any harm, and the conducting sea water will carry a good deal of the current around your body. In July 2006 a 50-year-old Briton was dangling his feet in the pool at a rented villa in Italy when lightning struck the water, killing him and injuring a friend. In 2014, the Journal of Geophysical Research published a map that amassed five years of global lightning-strike data from two weather satellites. Earth Sciences. hide. While the majority of lightning strikes hit the land, it is still possible for the sea to be affected: NASA research shows that deep ocean areas are less likely to be struck, with those nearer the coast more likely to be hit. Yes, they look dramatic, and some of those pictures are truly incredible. That’s because water is a reasonably good conductor, and a good conductor keeps most of the current on the surface.” So, when lightning hits the water, the current zips across the surface in all directions. Do fish die when lightning hits the sea? Answer Save. But below the surface, most of the electricity is instantly neutralized. I am just wondering what would happen if lightning struck near you while you were in the ocean. What happens when lightning hits the surface of the sea? Oceans Rarely Hit By Lightning. Technically, the lightning is already striking more than once. Q: If lightning strikes the ocean, do the marine animals get hurt or killed?

Despite water being a good electrical conductor, lightning doesn’t travel further in … Follow Newsbeat on Instagram , Facebook and Twitter . Lighting striking the sea is actually quite unusual . Why don't thunderstorms routinely kill off every animal in the sea? It will not prevent lightning from striking your vessel; it’s just merely a way to help dissipate it. However it does not significantly change the danger of electric shock, burns and sound pressure waves which are mostly the same for salt or fresh water lightning strikes if you're within the energy dispersal area. The old saying goes that lightning never strikes twice… but when it does strike, it can do so with catastrophic results. And Dr. MacGorman adds that some electricity does penetrate the water, right … Moreover, the proper calculation involves integrating $\rho/r^2$, which diverges unless the lightning strikes an extended area. That’s not all. The last confirmed commercial plane crash in the U.S. directly attributed to lightning occurred in 1967, when lightning caused a catastrophic fuel tank explosion. So if you were struck by lightning this is what would happen. Share this post. Of course, if the fish happen to be surfacing, they're at risk just like you are. A bonding system is a way to help protect your boat from lightning strikes. It … "The … When a electricity passes through biological tissues it heats it up and causes damage. where does the electricity go? A Bolt to the Blue. When lightning strikes land, it dissipates through the surrounding ground. “But superbolts happen mostly over the water going right up to the coast. Photo by: Gahsoon Gahsoon/EyeEm/ Getty Images. This thread is archived. The flow of warm ocean currents past drier ... it may separate into multiple bidirectional leaders. The charge from a lightning strike is dissipated within about 8 feet … NASA has shown with satellite imaging that the oceans rarely get hit with lightning. Firstly, and this was surprising to us, lightning strikes on the ocean compared to strikes on land is a rather unusual occurrence. Moreover, if the vessel does not have a metal hull and is not earthed to the water, the danger is multiplied considerably. Generally, lightning can travel for 20 feet through water before dissipating. Sign Up. When storm clouds come in contact, different particles come together during the process of electrical charging. Check out these 29 strategies for surviving lighting strikes when boating. #AskOceanX: What happens when lightning hits the water?" water is a conductor, so do the fish die? cyswxman. So the fish are generally spared. Swimming pools aren’t necessarily safer. Do the particles stay close to the surface and are only lethal if you are close enough to the strike? As simple as it gets, when the lightning bolt strikes the surface of the water, it discharges over the surface of the water sideways and expands a little downwards. The image below shows NASA's … The question is, if you’re in the water near the lightning strike, … 0. We know that water is a good conductor of electricity, so if lightning strikes water it will generate a current. New comments cannot be posted and votes … So the fishes are ok. Hope that helps!

The fish in the sea are not in the path of the lightning as the sea water around them is a better electrical conductor. Fl is not my idea of good times for boating unless the boat is big enough to have a mast that transmits the lightning strike down a wire into a big plate mounted to the boat under the water line … Potentially, lightning is the biggest weather danger for divers. it's puzzling.
