A ship travels on the sea. Suddenly, the wind was strong and the clouds were thick. The scene of a thunderclap hitting the tall mast was terrifying.
Due to its high metal mast, ships sailing at sea are easy targets for lightning strikes. Now, let me tell you something even more terrible: the activity of the ship itself is the cause of the thunderstorm!
This is a strange example of human activity altering the weather.
Recently, a scientist at the University of Washington looked at the record of lightning attacks on the World Lightning Locator Network from 2005 to 2016. He noted that some areas of the eastern Indian Ocean and the South China Sea had significantly more thunderstorms than other areas around them, and unusually, thunderstorms mostly occurred on two shipping lanes across the ocean, which happen to be the busiest in the world today. According to his count, the two lines have twice as many thunderstorms as nearby areas.
This result led him to believe that the thunderstorm here must be related to the activity of the ships. After some analysis, he concluded that the exhaust gases from the ship were to blame.
Particles create charged clouds. Modern commercial cargo ships are powered by the burning of coal or heavy oil. Heavy oil is the residue of gasoline, kerosene, and diesel that is fractionated from **.
Both fuels are heavily polluted. There are a lot of particles in the exhaust gas. When particulate matter is discharged into the atmosphere through the ocean, it can easily become a condensation nodule of water vapor, forming many small water droplets.
It turns out that if the air was clean, there wouldn't be so much tuberculosis. Water vapor grows around a small number of condensation nuclei, and the small droplets grow rapidly, becoming larger and heavier, until they are unable to bear the weight and form rain. <>
But on busy routes, there are so many condensation nodules that a large number of small droplets are formed. Everyone is competing for water molecules in the air, so the growth rate of water droplets slows down. They are therefore lighter and can rise to higher spaces, where they freeze into many Xiaoice crystals, forming clouds rich in ice crystals.
These Xiaoice crystals are responsible for the increase in thunderstorms: when many Xiaoice crystals are together, they can be charged by rubbing against each other; It is only when the clouds are charged that lightning is generated. If it's a simple small droplet, because it doesn't rub against each other and doesn't produce lightning.

It may be that when at sea, water can conduct electricity, so it is easier to induce.
-
Because the sea is basically nothing, only cargo ships are easy targets.
-
Because first of all, there are many stormy weather at sea, and it is basically iron.
-
Because they have so many things on this thing, that's why it's like this.

I don't think it's very small.
When the ship is sailing on the sea, it is often encountered in bad weather, and if the ship is under the cloud that produces thunder and lightning, it will not be struck by lightning. Because lightning always has to find a shortcut as its path. Steel has good electrical conductivity, and the distance to reach the steel is shorter than the distance to the sea, so if lightning occurs in the close proximity of the ship, it is still more likely to be hit.
From the perspective of ship insurance, the ship's all-risk insurance is excluded along with ** and volcano, etc. Therefore, this situation is still possible, otherwise the insurance company does not have to list it separately.
Even if the ship itself is struck by lightning, if it does not cause a fire, it is unlikely to endanger the safety of the ship, and modern ships are still more cargo ships with fewer people on board. Most of the passenger ships are short-distance passenger ships, and when the weather is bad, they will know in advance that they can not sail or make a detour. There is also a system on board the freighter to receive weather forecasts (we call them air conduction......Weather navigation), which can predict the weather conditions in the local and adjacent sea areas.
Finally, ordinary people learn all kinds of information mainly through television, the Internet, newspapers, etc.**. Even if a sea ship is struck by lightning, it is very rare to have a large loss, and it may endanger the lives of many people like civil aircraft, so for **, there is not much reporting value, and naturally it will not reach the ears of ordinary people.
To sum up, I think that it should not be an extremely rare thing for a ship to be struck by lightning, but because the loss is often very small, or there is no loss at all, and the news value is not large, there are few ** to report, and ordinary people naturally can't know.

1.Lightning Strike = Torpedo Mine Hit:
1) Modern aircraft carriers, especially large aircraft carriers, have a reasonable division of watertight compartments and a solid structure, and they cannot be easily sunk by one or two torpedoes.
2) In the case of a large civilian vessel such as an oil tanker, there is no compartment specifically designed to withstand or cushion the strong pressure generated by the torpedo**, let alone a 650 mm diameter super-large torpedo developed in Russia. If such a civilian ship is hit by a mine, a maximum of one torpedo will be held by visual inspection.
3) The boat depends on how small the boat is. Small boats of several hundred tons in general are not worth using torpedo attacks at all. Large ** boats are generally equipped with decoys against torpedoes.
Most of today's standard torpedoes are wire-guided torpedoes, which are difficult to circumvent. If the boat hits, it will probably be blown up into the sky. In the case of mines - it is generally difficult for a boat to trigger a mine -
2.If the landlord said that the lightning strike is the lightning strike......
Ships are generally equipped with special equipment ...... to avoid spring minesWood has something to do.
My family eats alkali and raw treasure, which is quite good.
In summer, due to the long days and short nights, people go to bed late and get up early, gather more, and have a relative lack of sleep, so they may feel tired after a morning of study and work, and the brain is deprived of oxygen after meals, so they naturally want to doze off at noon. In summer, the days are hot and long, and the nights are cooler, so some people arrange some activities at night, and the night duration is already short, so people have less sleep, so that the biological clock is disordered, and it is easy to get sleepy during the day. >>>More
Because such mothers have some psychological problems, they will show these problems when educating their children.
We know that flying a kite always involves pulling the kite into the wind for a certain distance, with the aim of increasing the speed of the kite relative to the air, so that it can get more lift and rise faster. Similarly, the airplane should also run a distance before takeoff, so that it can produce enough lift to leave the ground, if it takes off under the headwind, the plane has not yet taxied and has a certain speed relative to the air movement, and gets a part of the lift, at this time the aircraft only needs a relatively small speed to reach the lift required from the ground, so compared with no wind, the distance of the glide is shorter. On the other hand, when an airplane takes off downwind, the plane needs to reach a large speed to reach the lift required to get off the ground, so the glide distance is relatively longer. >>>More
This is because anxious women tend to be insecure. It is especially easy to lose one's way in marriage, so it is especially prone to problems.
