The hot weather this summer

The unusually high temperature weather not only caused many people to die of heatstroke, but also led to the continuous reduction of grain production. It can be said that this year's unusually high temperature event affected more than 900 million people in China, and the whole summer was very painful. Then why is there such a serious high temperature weather? What is the reason for the hot weather?

1. Affected by atmospheric circulation anomaly. Extreme high temperature weather is directly related to the atmospheric circulation system, such as consistency, which leads to the warm subtropical high pressure circulation system controlling a large area in central and eastern China and forming a large-scale global warm high pressure zone. In the case of high temperature environment, staying in this area for a long time, the subtropical high pressure system is out of control for a long time, and finally it is difficult to spread on the ground for a long time, forming high temperature weather.

2. Global warming. The unusually long weather this year is also directly related to global warming, and it is no secret that global warming is like this. As early as after the industrial development, the temperature is actually rising every year, especially in recent years, with the continuous emission of automobile exhaust and the large amount of fuel needed for industrial production, the heat energy will continue to rise. The problem of accelerating global warming will also show this phenomenon.

How to cool down in summer?

1, use air conditioning. In the face of severe high temperature weather, air conditioning must be used in this case, otherwise it will easily lead to heatstroke or heatstroke.

2. Open the window for ventilation. In hot conditions, if family conditions do not allow frequent air conditioning, you must use an electric fan. And open the doors and windows at any time, which can play a role in ventilation.

3. Go to the summer resort. For places where the situation is more serious, you can also choose to go to a cooler place in the mountains for the summer. This can not only relax the mood, but also achieve the purpose of summer vacation.
