Did Northeast China hit the old nest of typhoon this year? Scientific analysis of why typhoons landed in Northeast China one after another

On the formation of typhoons, after consulting the data, the author found that there are two very important conditions for the formation of typhoons. The first is relatively high temperature, and the second is rich water vapor. Therefore, typhoons usually appear on the tropical sea surface. So here I give a simple example, through comparative argument to clarify the fact: for example, when the water boils, the water in the pot will continue to boil upward, especially the water at the bottom of the pot, so we can see bubbles of different sizes in foreign aid. Because water gets heat, the volume of water changes and expands. Return to the natural phenomenon, if the air is heated and rises, it will just encounter some clouds in the atmosphere. At this time, the ground pressure will inevitably decrease, and the air flowing in from the earth’s rotation will make the two kinds of wheels rotate like wheels. If there is water vapor blessing again, the air will be heated and rises, and it will encounter clouds, and precipitation will appear. Therefore, precipitation and typhoon are basically in pairs.

However, the reality is that northeast China has recently encountered a lot of strong typhoons, and because of continuous heavy rainfall and strong winds, many crops have fallen, which is very rare in Northeast China. So Northeast China seems to have poked a typhoon nest this year. What’s the matter?

I believe you all know that the fire in Australia in 2019 and the melting of the Arctic iceberg this year are very fast. In July this year, there will be very few typhoons in Shanghai and Northeast China. The time line goes back to August and September. Why are there more typhoons in August and September?

Originally, according to the report of the Meteorological Bureau, the latitude and longitude of this year’s climate is actually biased. In addition, the accelerated melting of icebergs and glaciers in the Arctic circle also leads to high heat in the Arctic region. In contrast, the high heat in Siberia also means that there is no more cold air for it to bend to the Japanese islands. Without the power of backward strong propulsion, the cold air can not move to the original correct position.

In addition, there is the subtropical high pressure belt, which is northward than in previous years. Due to the increase of temperature, the pressure is already on the high side, which will lead to a phenomenon. The investigation report of the China Meteorological Administration has shown that its position is much northward than before, and the most important point is that it has been distributed in blocks, so the typhoon must move along with the low pressure belt Yes. Therefore, the subtropical high pressure belt first goes westward and then northward, so it is easier to reach the northeast.

The second point is the cold air. As the El Nino phenomenon is more obvious this year, the strong cold air activity is still quite intense in the north. When the typhoon goes deep into the mainland, its force is weakened – because it is weakened by the terrain. If there is cold air. In fact, it provides water vapor for typhoon and power for cold air. The combination of the two will form very strong cold air and precipitation. In this case, if you want to wait for a typhoon to pass, it will take a long time, because the power of this kind of typhoon is many times higher than that of ordinary typhoons.

in the final analysis. In fact, it is because of excessive human activities that lead to global warming. After entering the greenhouse effect, the Arctic and Antarctica are getting hotter. Even polar bears and other animals are unable to hunt normally. Naturally, it is not necessary to mention the poor ecological environment. This can be said to be a series of butterfly effects. Of course, human beings have now realized their own problems and are actively making improvements, hoping that human beings can protect their homes.
