Why is the global weather abnormal this year?

The Central Meteorological Observatory issued a forecast: With the influence of the last round of cold air coming to an end, the temperature in most parts of the central and eastern regions will obviously rise, and the highest temperature in many places will exceed 20℃. However, with the departure of a new cold air in northern Xinjiang, most parts of the north will gradually cool down in the next three days, and some areas will be accompanied by windy and dusty weather.

The temperature rises and falls like a roller coaster, which seems to be the normal state this spring: at the end of March, the warm and humid airflow suddenly strengthened northward, and the temperature in most parts of the south began to flee like wild horses. Soon, the temperature in Jiangnan area broke through the 30℃ mark, and even exceeded 35℃ in some areas, reaching the standard of high temperature weather, just like summer. On April 1 day, high temperatures emerged in central Sichuan, western Chongqing, western Guangxi, Hainan and other places, and Chongqing won the first high temperature day this year, 35.7℃! On April 5, on the eve of the arrival of cold air, the temperature before the front obviously rose, and the temperature in western Guangxi and Fujian was like midsummer.

Just when people thought that warm spring was a foregone conclusion, a strong cold air embarked on a counterattack. Its arrival not only brought an unusually heavy rainfall to the middle and lower reaches of the Yangtze River, but also made this year's Qingming holiday chilly. On April 6, the highest temperature in most parts of the south of the Yangtze River was only a dozen degrees Celsius. On the night of April 7th, the temperature dropped below 10℃ in most parts of the south of the Yangtze River, below 5℃ in the middle and lower reaches of the Yangtze River, and even below 0℃ in higher-lying areas. "Peach Blossom Snow in April" appeared in mountainous areas such as Zhejiang, Hubei and Anhui.
