Since June 2, 2020, the Central Meteorological Observatory has issued a rainstorm warning for 30 consecutive days, the duration of which is rare in recent years.

According to the latest news from the Central Meteorological Observatory, the rainstorm will continue in July 1 day. It is estimated that there will be heavy rains in eastern Sichuan, most of Chongqing, most of Guizhou, northern and western Yunnan, northwestern Guangxi, southern Zhejiang and northern Fujian, among which there will be heavy rains in western and southeastern Chongqing, southwestern and central Guizhou and southwestern Hubei.

Some of the above areas are accompanied by short-term heavy rainfall (the maximum hourly rainfall intensity is 20 ~ 50 mm, and the local area can exceed 60 mm), and there are strong convective weather such as thunderstorms and strong winds.

Why is there a constant rainstorm in the south this year?

According to the statistics of China Weather Network, since June 1 this year, there have been five rounds of heavy rainfall in southern China. The accumulated rainfall of nearly10.5 million square kilometers of land exceeds 200mm, that of 700,000 square kilometers exceeds 300mm, and even that of about 50,000 square kilometers exceeds 500mm.

And since yesterday, a new round of heavy rainfall "curtain" has been opened, but this time the main areas of heavy rainfall began to "fight" to the eastern part of southwest China to the eastern part of Jiangnan.

Today and tomorrow, the heavy rainfall belt will move northward again, and there will be heavy rain in the east of southwest China to the south of Jianghuai and the north of Jiangnan, accompanied by strong convective weather such as short-term heavy precipitation; In addition, western Guangxi and southern Yunnan will also join the camp of heavy rainfall.

And why is there a constant rainstorm in the south this year? He Lifu, chief forecaster of the Central Meteorological Observatory, explained, "This is due to the strong intensity of subtropical high this year, resulting in relatively stable rain belt. At the same time, the southwest monsoon blowing from the Indian Ocean to the South China Sea developed strongly, and the weak cold air in the northeast frequently went south, forming a strong warm and humid airflow, which led to continuous heavy rainfall in the south.
