Weather trends in China.

Because of the exercise of cold air, when cold air comes, most areas will cool down.

The greenhouse effect is the chief culprit of this extreme high temperature, and the chain reaction caused by high temperature leads to La Nina phenomenon, which may not be familiar to everyone. The popular explanation of La Nina phenomenon will lead to the polarization of climate, that is, it is hotter in summer and colder in winter. At present, there is no definite evidence that La Nina has occurred in China, but the National Meteorological Observatory estimates that it is likely to happen this year. Therefore, this winter will be different from the past. Besides the early winter, we may witness another cold winter, which will make history in the future.

With the increase of temperature, it can be said that high temperature has entered the northern part of China, and the area above 30℃ in the north is still expanding. In the next three days, the highest temperature in parts of northwest and northern North China will be close to or higher than 25℃, and the highest temperature in the middle and lower reaches of the Yangtze River will be around 27℃. Among the provincial capital cities, the temperature in Jinan, Zhengzhou and Changsha can be close to 35℃, which will be an early version of summer. Therefore, there will be a high temperature of 30℃ in the north.

This year, the global climate is very changeable and extreme, and extreme high temperatures have appeared all over the world. For example, in Europe, the environment used to be very comfortable, but now the temperature has reached 40 degrees. In China, there are also many cities and regions with severe high temperatures, and the number of residents affected by high temperatures has exceeded 900 million. It can be seen that the high temperature has a great impact on the lives of residents, and even several people have died of heatstroke; At the same time, this year's climate is not only high temperature, but also extremely heavy rainfall. Even after high temperature, there will be hail, which is very strange.

For example, human beings should reduce industrial waste gas emissions, reduce part of coal-fired power generation, and use more wind power generation, hydropower generation and solar power generation, which can greatly reduce greenhouse gas emissions; At the same time, people can also try low-carbon life in the process of life, which can effectively protect the global environment.
