Scientists say that if there were no typhoon, the already serious global water shortage problem would be more serious. The appearance of typhoon, a tropical ocean storm, can provide a large number of fresh water resources for human beings in time.
According to estimates, a typhoon with a small diameter can bring nearly 3 billion tons of precipitation when landing. Take the Pacific Northwest near China as an example. There are about 30 typhoons every year. After landing in the west, the rainfall brought to the coastal areas of China, Japan and other countries often accounts for more than 25% of the total precipitation in that year.
If there were no lightning, mankind would lose a diligent "cleaner" When lightning strikes, some oxygen in the atmosphere is violently converted into ozone by high temperature and high pressure. 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 reach 30,000 degrees Celsius, which can kill more than 90% of bacteria and microorganisms in the atmosphere, thus making the originally turbid air fresh after a thunderstorm!
If there were no lightning, mankind would lose a huge "fertilizer plant". It turns out that the atmosphere contains 78% free nitrogen, which cannot be directly absorbed and utilized by plants. However, after high temperature treatment during lightning, air molecules are heated to 30,000 degrees Celsius, which makes these inert nitrogen in the atmosphere combine with oxidation and become nitrogen dioxide. Heavy rain dissolves nitrogen dioxide into dilute nitric acid, which falls to the ground with rain and combines with other substances, and finally becomes nitrogen fertilizer that crops can directly absorb. According to calculation, the natural nitrogen fertilizer "synthesized" by thunderstorm emissions worldwide exceeds 2 billion tons every year. That is to say, the natural nitrogen fertilizer "manufactured" by lightning in the world is equivalent to the sum of the annual output of 200,000 small nitrogen fertilizer plants with an annual output of 6.5438+100000 tons.
