On March 1, the Office of the National Disaster Prevention, Mitigation and Relief Committee and the Ministry of Emergency Management released the national natural disaster risk situation in March.
According to the comprehensive analysis, with the increase of temperature, the national natural disaster risk situation in March is more complicated, the strong convective weather in some areas of East China and Central China increases, the risk of floods, hail disasters increases, and the Inner Mongolia section of the Yellow River will be opened in mid-March. The risk of low-temperature rain, snow and freezing disasters is higher in some areas such as Northeast China, Inner Mongolia and **; The risk of local geological disasters in East China, Central South, Southwest China, and Northwest China is high. Most provinces in the country have entered the spring fire prevention period, and some areas such as southwest and southern China have high forest fire danger levels; There may be 4-5 dust processes in the northern region. The details are as follows:
The first is the risk of floods, winds and hailstorms. It is expected that in March, the eastern part of Heilongjiang, most of Jilin, Liaoning, southern Anhui, Shanghai, Zhejiang, northern Fujian, central and northern Jiangxi, eastern Hunan, and northwest China will receive more than 2-5 percent of precipitation. Heavy rain or localized heavy precipitation in eastern and central China and southern China may cause floods, and severe convective weather may cause hail disasters. At present, the Inner Mongolia section of the Yellow River has entered the opening period, and it is expected that the frozen section of the Inner Mongolia River will be opened in mid-March, which is earlier than the average full opening date (March 25). Some frozen sections of the river in Northeast China will be opened one after another, and it is necessary to pay attention to the development of Lingqing.
The second is the risk of low-temperature rain, snow and freezing disasters. It is expected that in March, the temperature in the northwest of North China, the northern part of Northwest China, the central and western parts of Inner Mongolia, and the northern part of Xinjiang will be low, and there will be a risk of periodic cooling and strong wind disasters. Northeast China, eastern Inner Mongolia, central and northern Inner Mongolia have more precipitation, and the risk of low-temperature rain, snow and freezing disasters is high. Affected by cold air and other factors, one catastrophic extratropical storm surge process and three to four catastrophic wave processes may occur in China's coastal and offshore waters.
The third is the risk of geological disasters. It is expected that in March, the risk of geological disasters will be high in western Zhejiang, southern Anhui, northern Fujian, northern Jiangxi, eastern and southwestern Hubei, central and northern Hunan, northern Guangxi, eastern and southern Chongqing, northern Guizhou, southern Gansu, and eastern Qinghai.
Fourth, the risk of forest fires. At present, most provinces in the country have entered the spring fire prevention period. In March, the forest fire danger level in northern Beijing, northern Hebei, central and eastern Shanxi, northern Jiangsu, central and southern Anhui, southern Fujian, southern Jiangxi, central and eastern Shandong, central Henan, eastern Hubei, southern Hunan, most of Guangdong, northwest Guangxi, western Hainan, western and southern Sichuan, western Guizhou, most of Yunnan, southeastern **, and southern Shaanxi was at a high risk. Among them, the forest fire danger level in southern Fujian, eastern Guangdong, northwestern Guangxi, western and southern Sichuan, western Guizhou, central and northern Yunnan, and southeastern China is highly dangerous.
Fifth, the risk of sand and dust disasters. In February, the first sandstorm process in 2024 affected Xinjiang, Gansu, Ningxia, Inner Mongolia, Shaanxi and other places, with strong sand and dust intensity and early occurrence, which had a great impact on the Spring Festival transportation in many provinces. It is expected that in March, the number of sand and dust days in the northern region is generally close to the same period of the year to more, there are 4-5 sand and dust processes, and the intensity is generally close to the same period of the year to the strong, and it is necessary to pay attention to the adverse impact of sand and dust weather on transportation, energy and agricultural production.
