If there were no lightning, mankind would lose a diligent "cleaner" When lightning strikes, some oxygen in the air will be excited into ozone. Thin ozone is not only tasteless, but also absorbs most cosmic rays, which protects the life on the surface of the earth from excessive ultraviolet rays. The high temperature generated during lightning can kill more than 90% of bacteria and microorganisms in the atmosphere, thus making the air more pure, fresh and pleasant.

If there were no lightning (_ Jiaruyoumei lightning), mankind would lose a huge "fertilizer plant". It is estimated that there will be more than 365,438+billion lightning flashes over the earth every year, with an average of 100 per second. The electric energy (CI4 _ MEI3CI4FANG4Dian4 _ QI2Dian4Neng2) discharged each time is as high as 52700 kWh, which cannot even be compared with the largest power device in the world. The air contains 78% nitrogen that cannot be absorbed by crops. When lightning strikes, the current is as high as 654.38+ million amperes, and air molecules are instantly heated to over 30,000 degrees Celsius, so that nitrogen in the atmosphere combines with oxidation to generate nitric oxide. Nitric oxide is then converted into nitrogen dioxide. Rainwater reacts with nitrogen dioxide to produce nitric acid. Rainwater containing trace nitric acid is a nitrogen fertilizer that crops can directly absorb after falling to the ground. It is estimated that 500 million tons of nitrogen fertilizer are "synthesized" by thunderstorms (lightning) every year in the world. This 500 million tons of chemical fertilizer fell from the sky, which is equivalent to the total output of 50,000 chemical fertilizer plants with an annual output of 6,543,800 tons.
