　　Do not drink raw water after rain, try to avoid wading barefoot

　　According to Xinhua News Agency, from May 9, southern China has ushered in the heaviest rainfall since the flood season this year.

On the evening of the 11th, the Central Meteorological Observatory issued an orange rainstorm warning, which is the first orange warning for heavy rain this year and the earliest orange warning for heavy rain in the past 10 years.

　　From 8:00 on the 12th to 6:00 on the 13th, heavy rains occurred in parts of central and southern Guangdong, southeastern Guangxi, southeastern Fujian, and southeastern Zhejiang. Heavy rains occurred in Zhuhai, Jiangmen, Shenzhen, Shanwei, Heyuan, and Zhangzhou, Fujian. , Guangdong Zhuhai and Jiangmen, Shanwei and other local heavy rain (250 ~ 453 mm).

In the next three days, the range of heavy rainfall in South China will gradually shrink, and there will still be heavy to heavy rains along the coast.

　　Where does the rainstorm come from?

Why early?

　　From May to June every year, it is the peak period of the "Dragon Boat Water" rainstorm when South China enters the flood season.

But this year, the "Dragon Boat Water" is not only a lot more fierce, but the time has also moved forward from late May to early June to mid-May in previous years. Why?

　　First of all, it is because the South China Sea summer monsoon is agitated ahead of time. According to the prediction of the East Asian summer monsoon circulation by the National Climate Center, the outbreak of the South China Sea summer monsoon this year is earlier than in previous years. 15th of May), while in previous years it generally starts from the fourth quarter of May.

This directly caused South China to enter the flood season ahead of schedule.

The South China Sea summer monsoon is one of the important monsoons that affects the weather in my country. After its outbreak, the air flow entrained by the monsoon will move northward.

For us, this means that the southwest warm and humid water vapor carried by the airflow will enter the southern part of our country in an all-round way, making the southern part of our country enter the flood season.

　　Second, the Bay of Bengal storm did not make landfall in the western Indian region as expected, but stayed where it was.

This makes it provide a steady stream of water vapor for the warm and humid air flow, which makes this year's "Dragon Boat Water" rainstorm tend to increase on the basis of previous years.

　　Finally, the cold air from the north to the south is more abundant than in previous years, and the arrival time is also earlier. While promoting the early outbreak of the "Dragon Boat Water", it also added "a handful" to the rainstorm.

　　Guangdong Province disease control experts reminded that typhoon and flood disasters can easily cause water pollution, food pollution or deterioration. In addition to food poisoning, unclean diet and drinking water can also spread infectious diseases such as dysentery.

　　Citizens should pay attention to personal hygiene and food hygiene, keep hands clean, do not drink raw water, do not eat livestock whose cause of death is unknown, and thoroughly clean up the indoor and outdoor environment.

Try to avoid wading barefoot.
