What are the main reasons for frequent rainfall and more extreme weather in recent years?

There is more and more rain, mainly in the north of China. The rainfall in the whole north has increased by more than 1 time compared with the same period, which is the highest level in the same period. In recent years, the rainfall in the north is abnormal, and the frequency of heavy rain has increased significantly. Even after autumn, the rainstorm process is very obvious.

In meteorological science, when defining extreme weather, it is defined by the probability of a certain weather. Usually, when the probability of this kind of weather is less than 10%, it can be called extreme weather, such as the rainstorm in Zhengzhou and the rainstorm in Shanxi. In addition, the persistent high temperature in the south since autumn is very different from the same period in history, so we can really say that there are more and more extreme weather, and the root of all this is global warming.

In fact, as early as 20 16, the World Meteorological Organization (WMO) warned that in the context of global warming, there will be more and more extreme weather, and people should be alert to the increasingly frequent extreme weather such as high temperature, rainstorm, tornado and typhoon. Many people may be surprised and don't understand the relationship between global warming and rainstorms and typhoons. Because in ordinary people's understanding, global warming means that the earth's temperature is getting higher and higher, but in fact this is only the most direct surface impact. In fact, global warming affects the climate system of the whole earth, adding instability to the climate system of the earth.

Here, the earth's climate system can be personified. Every normal person has a perfect circulatory regulation system. It is the existence of this system that enables human beings to have a series of abilities such as thinking, digestion, exercise and recovery. Under normal circumstances, this circulatory system will continue to work steadily, and once a person eats too much fat and salt, it will increase the burden on the normal system of the body.

On the surface, a person's obesity will not completely affect the normal function of the body, and exercise and thinking can be carried out normally, but obesity will also increase the probability of chronic diseases such as hypertension, diabetes and hyperlipidemia, leading to an increase in the probability of extreme variation in the body. The fat and salt here are equivalent to greenhouse gases emitted into the atmosphere by human beings, which have direct and indirect effects.

As for greenhouse gas emissions, I believe there is no need to discuss them too much, and most people know it. However, the cause of climate warming cannot be blamed on a group of people, because almost all commodities in the industrial age are related to greenhouse gas emissions, so we can't enjoy the convenience brought by industrialization while spitting out the greenhouse gases formed by industry. In fact, greenhouse gas emissions are related to all mankind.
