202 1 why did it gradually cool down in the second half of the year? Is it because of La Nina?

April this year is still the same as winter, wearing thick sweaters to keep out the cold, and we can't help wondering why the weather is so changeable. At this time, some people will say, in a few months, you will know the cruelty of the world. It's so hot, do you even doubt that you need to wear clothes? The heat in the south is not as hot as expected. I don't know if it is the cause of the "fireworks" of table lamps, but the typhoon has also turned Henan into a "water city".

There is much more rain this year than in previous years, but it is not the case in other countries. The United States leads an extremely dry life, with the highest temperature approaching 50 degrees Celsius. At the same time, the same is true in the Middle East. The camel actually fell on the side of the road, which is also very embarrassing.

What about the high temperature in China as always? Judging from the experience of such a strong typhoon, with the northward movement of the typhoon, heavy rainfall occurred in the whole area where the typhoon experienced. Is there no high temperature this summer?

Careful observation of the temperature map shows that most areas are still around 35 degrees Celsius, and only the southeast side near Haicheng has a temperature of 30 degrees Celsius, which is a cool summer for people there.

This distribution is basically hot in the north and south, and only the eastern coast is cooler. It sometimes rains and cools down in the south, but it's hard to explain it in the north. What is the reason for the high temperature in the north? Why does this strange phenomenon appear in the north?

This phenomenon in northern China is actually due to the influence of the "hot dome" in North America, which is inseparable from the La Nina that appeared before. Even temperatures below 35 degrees Celsius can make people feel uncomfortable. Although the temperature is very low, the sultry feeling is still there.

How did such extreme weather come about? There has never been a drought in the United States, and there have been heavy rains in China and Europe. Some experts speculate that this is still caused by global warming, which will have such a great impact.

As we all know, global warming is caused by the emission of a large number of greenhouse gases, which will lead to higher energy in the atmosphere after being absorbed by the atmosphere, and then discharged through other channels.

The strong typhoon "fireworks" in China may also be caused by this reason. Throughout China, from the south coast to the north, "fireworks" destroyed many building facilities, and because of this, the lost resources in Henan were used by hundreds of millions.

Because of this global warming, we should bear the extreme drought or rainstorm that will eventually lead to it. After all, it is our own business.

What will the weather be like on earth in the future? It is reported that the water vapor in northern China will increase again in the future, forming an unprecedented wet period. If you think about it carefully, it's not impossible. These water vapor will form rain and snow, and then impact the cold current in the North Pole.
