![]() ![]() "The mysteries have not been recognized and are not known by the general public. (By the way, this is why it is safe to be in a car in a lightning storm. "It's an amazingly interesting subject," he said. If it does, does the electrical current fry the fish Question Date:. Although scientists now assume that lightning is static electricity created by the motion of ice particles in thunderclouds, that isn't known for sure, Lowke said. For example, it may inform the placement of lightning rods on tall objects such as buildings, radio masts and ship superstructures.Īmong the lingering questions about lightning are what causes it. The other leaders lose their charge at this point and disappear.Ī better understanding of how lightning works can help structures and people survive thunderstorms, Lowke said. Reproduced from Malecha, M., Schmidt-Eisenlohr, C., Kaufmann, P., Rähtz, C. The layup head moves in the direction of the arrow onto the mold surface (thick black line). That impact results in the visible ( and very loud) "return stroke" of the lightning bolt for about one-thousandth of a second, traveling back along the zigzag path of the highly conducting singlet delta oxygen, he said. Lightning does not have to strike a conductor in order to inject transients on to the local network, ‘impulses’ can be induced if lightning strikes near a conductor. The leader discharges across successive steps in about a millionth of a second, each followed by a fleeting "dark" period where the photographs show no visible discharge at all, and finally hits the ground or a tall object connected to it. The powerful magnetic fields from the last step almost instantaneously create additional singlet delta oxygen molecules from the regular oxygen molecules in the atmosphere, and concentrations of this highly conductive oxygen can branch out in all directions from where the step ends, he explained. Could a powerful solar storm wipe out the internet?Įach "zig" (or "zag") of a leader - a "step" which is about 165 feet (50 meters) long - is caused by electric charge discharging across such a region, Lowke said. Did Benjamin Franklin really discover electricity with a kite and key? ![]()
