Why are hot weather frequent in recent years?

According to the China Meteorological Bureau, the temperature in many places in China has recently broken records. The nationwide high temperature is affecting our country. Why is it so hot this year? Meteorologists said that this high temperature was affected by the northward shift of the subtropical high pressure belt, and the high temperature weather will continue to expand in the future, and there will be continuous high temperature weather in the north and south, and this high temperature weather will last for a long time and its intensity is relatively large.

Affected by the northward shift of the subtropical high belt and the maritime climate in the east, high temperature weather occurred in the southeast of China for several days, causing large-scale rainfall and seriously affecting the lives of local people.

Is it normal to have hot weather? According to the China Meteorological Bureau, since mid-June this year, there has been a large range of high temperature weather in China. Sichuan basin is the most obvious. Because the Sichuan basin is a basin area, the air pressure will sink and the warm air mass will gather together, which will lead to the abnormal dryness of the Sichuan basin, so it is normal to have high temperature. And this high temperature will last for a long time. At the same time, because the high pressure will extend eastward and connect with the subtropical high belt in the eastern part of mainland China, a warm high pressure will be formed in the western plateau of China, which will lead to a large-scale high temperature in the western region again.

According to the data of the World Meteorological Organization, the global greenhouse gas concentration and sea level height have set new records in the past year, which is another obvious change in the global ocean atmosphere caused by human activities and will continue to cause harm to ecosystems and natural systems. Therefore, it is not unrealistic for China to have an unusually high temperature this year due to global warming.

To sum up, the author believes that the state should introduce relevant policies to curb carbon dioxide emissions. Promote the development of emerging industries, raise people's awareness of environmental protection, and let people calmly face the sudden bad high temperature weather. In the long run, if people can nip in the bud, fundamentally curb the occurrence of high temperature weather and raise environmental awareness, then we can also face it calmly.
