Hi steemians. How are you today? I hope you are glad. Today I want to share about It turns out that lightning can strike twice at the same place.
An old saying that lightning never strikes twice in the same place is not necessarily true. Based on observations it turns out that in Lake Maracaibo, Venezuela there are 1.2 million lightning strikes per year. Even in more general places, there are two or more lightning strikes that follow the same route to the ground in just a few seconds to each other. To know scientifically the causes of this phenomenon, a radio telescope network is needed.
Scientifically it can be explained that updrafts will separate positive and negative particles in the cloud. This will create an electric field around it. When the separation becomes strong enough the air changes to the plasma so that lightning can jump. Channels will form well in the cloud or between clouds and soil. This can produce lightning. It turns out that the negative charges inside thundercloud don't run out all in one flash. But some is stored next to the main channel so that it can trigger a second attack.
Please note that lightning starts from the initiation point and moves in two directions at once. The positive leader moves towards the negative charge to neutralize it. Instead, negative leaders do the opposite. The behaviour of the two leaders of this charge is different. Negative leaders usually take their own steps while emitting strong radio waves, while positive leaders move more smoothly and quietly on the radio.
Scientists discovered a feature they called a "needle". This feature has a length of 10-100 meters (30-330 feet) and a width of fewer than 5 meters (16 feet) and branching out from a positive leader. This feature is able to travel at a speed of around 300 km / s (720,000 mph) where they draw loads from the main channel.
Meanwhile, the remaining negative charges can be removed. The expenditure process reuses the same channel where facts that might be very useful to know. Scientists hope such work will one day be useful in limiting the damage lightning can do, perhaps in improving the design of lightning conductors. Thus humans can avoid or reduce the negative effects of this event.
