Why is the weather so abnormal?

1, the highest temperature in Nanjing reached 29.6℃ yesterday, the highest in 50 years; 2. The temperature in Wuhan soared, and the highest temperature almost reached a record high of 30 degrees Celsius; 3. The highest temperature in Zhengzhou reached 28.5℃, which broke the extreme value of the highest temperature in mid-March in recent 60 years since Zhengzhou had meteorological records.

The reason why the temperature is so abnormal is mainly because the cold air in the north is weak recently. From the end of February to the beginning of March every year, it is the season most frequently affected by cold air in the north. After the end of cold air, the forces of warm air have always prevailed, so the temperature is rising day by day, which finally broke the highest record in early March since the same period in history.

Sudden weather changes are not uncommon and occur almost every year, reflecting that atmospheric circulation is also affected by multiple factors, which is also the main reason for abnormal weather. Meteorologists analyzed three main reasons: first, the heating mass is very strong at present; Second, the southwest wind blows near the ground; Third, the sky is clear and the sun is strong. Coupled with the recent lack of cold air in the north and south, most of them come and go in a hurry, causing the temperature to fall and rebound like spring. Among them, the southwest wind is the "behind-the-scenes pusher" of rising temperature.

Of course, as upstairs said, the abnormal weather now has a considerable relationship with human wanton destruction of nature.
