Disaster assessment in May:

1.Extreme precipitation occurred frequently in southern China, and both urban and rural areas were affected

In May, most of the south of the Yangtze River, central and eastern parts of South China, and the eastern part of the precipitation were generally more frequent. The southern region experienced five large-scale heavy precipitation processes. Fujian, Jiangxi, Hunan, Guangdong, Guangxi, Guizhou and other 6 provinces (autonomous regions) had average precipitation and heavy rain. The number of days is the highest and highest in the same period in history since 1976.

The amount of precipitation in the southeastern coastal areas of Guangdong is 1-2 times more frequent. The precipitation in Guangdong Conghua (May 23, 288.7 mm) and Hunan Xinshao (May 25, 159.6 mm) exceeded the historical extreme.

Over-warning floods occurred in 67 rivers in Guangdong, Guangxi, Fujian, Hunan and other places. The Lianjiang and Lajiang tributaries of the Beijiang River in Guangdong, the Lushui tributary of the Xiangjiang River in Hunan, and the Zishui tributary Shaoshui of the Xiangjiang tributary of Hunan experienced extreme or historical floods.

On the whole, floods occurred more severely in May. The number of emergency resettlement populations and collapsed houses were the second and third largest in the same period in the past decade. Guangdong, Jiangxi, Hunan, and Guizhou were the worst affected.

Affected by the rainfall, 13 sections of 5 national highways and 136 sections of 27 provincial highways in Guangdong Province were washed out. Shenzhen suffered the strongest rainstorm since 2008, about 150 roads in the city were flooded with water and many cars were flooded, multiple flight cancellations. Hengyang, Huaihua, Hunan, and the ancient city of Fenghuang, a tourist attraction, experienced waterlogging during the Dragon Boat Festival at the end of May, which had a greater impact on local tourism.

2.The earthquake occurred continuously in Yunnan, and the effect of disaster superposition was aggravated

In May, there were 10 earthquakes of magnitude 4 or higher in my country's mainland, and the overall number of earthquakes was slightly lower than that of the same period in recent years. Among them, there were 3 earthquakes of magnitude 5 or above, all of which were located in Yingjiang County, Yunnan Province. They were the magnitude 5.6 earthquake that occurred on May 24, the consecutive magnitude 6.1 and magnitude 5.1 earthquake swarms that occurred on May 30. Many people were injured, a large number of houses collapsed and damaged, and various infrastructures were damaged to varying degrees, which caused serious impacts on the production and life of local people.

In addition, the magnitude 4.7 earthquake in Yuanmou County, Chuxiong Yi Autonomous Prefecture, Yunnan Province on May 7 also caused damage to some houses. From the perspective of the disaster situation, the number of emergency resettlement populations and collapsed houses caused by the earthquake disaster in May is second only to the 2008 Wenchuan earthquake.

3.The contrast between low temperature and high temperature is strong, and the freezing heat wave comes one after another

In May, the periodical characteristics of the national average temperature were remarkable. The first half of the month was the lowest value of the same period since 1997; the second half of the month was the second highest value of the same period since 1961. On the one hand, the northern region has suffered three strong cooling processes. For example, in early May, some areas such as Northeast China, North China, and Inner Mongolia had a maximum temperature drop of over 8℃. The lowest temperature in Yangyuan County, Zhangjiakou City, Hebei Province fell to -5℃ in the early morning of May 5, low temperature freezing and snow disasters have caused heavy losses of corn, wheat, vegetables and other crops in some areas. The affected area and direct economic losses of crops are the largest in the same period in the past 10 years. On the other hand, large-scale high temperature weather occurred in North China, Huanghuai, and Southwest China. The area with a high temperature exceeding 35C was about 720,000 square meters. A total of 155 monitoring stations had extreme high temperature events. Yuanyang, Yunnan (May 18, 44.5℃), Hebei Zhengding (May 29, 43.4℃), Beijing Changping (May 29, 42.2℃) and other 34 monitoring stations, the daily maximum temperature exceeded the historical extreme.

Among them, from May 26 to 31, large-scale continuous high temperature weather occurred in North China, Huanghuai and other places, and dry and hot winds occurred in the central and southern parts of North China and most of the wheat areas of Huanghuai. The development of wheat was severely affected, and the farmland experienced premature aging and forced ripening.

In addition, the precipitation in most parts of Yunnan was 50-80% less than that of the same period in normal years, the temperature was 1-4°C higher, and the drought continued to develop.
