According to the statistics of National Climate Center, the average temperature is 196 1 year. What is the cause of the abnormality?

According to relevant media reports, the National Climate Center said that the average temperature was 196 1, the highest since. Seeing this news, many people think it is really necessary, because the temperature in some areas has exceeded 40 degrees Celsius this summer and has been maintained for a month. This phenomenon is extremely rare. Even for decades, no such abnormal weather has been found.

What caused the abnormal weather?

1. Caused by abnormal atmospheric circulation. This summer, the global atmospheric system showed a consistent warm and high pressure circulation system control, forming a large-scale global warm and high pressure zone. Affected by the high-pressure system, hot air will always be on the ground and cannot be dispersed. In this case, the temperature will continue to rise, so it will be manifested as abnormal weather.

2. Global warming. According to relevant data, in fact, after human beings entered the industrial age, the temperature gradually increased every year. Only in recent years, the situation will be more serious, leading to rapid global warming, which is also one of the important reasons for abnormal weather.

3. Urban effect. Now people's living conditions are getting better and better. In this case, every household will use some electronic products or car supplies. No matter what kind of electronic products will emit corresponding heat, followed by automobile supplies, which need to use fuel, and will also induce the problem of hot weather. In addition, the large urban population is also one of the important reasons.

Content summary.

This year is indeed the highest temperature in recent decades, and there are some extreme areas, even a high temperature of 40℃ a month, and there is no rainfall. In fact, the occurrence of abnormal weather is mostly caused by abnormal atmospheric circulation, global warming and urban effects. However, during this period, it is not excluded that it is caused by other reasons, such as marine factors, thermal effects of the Qinghai-Tibet Plateau, and factors at middle and high latitudes.
