China News Service, August 3. According to the official Weibo news of the Ministry of Emergency Management, recently, the Office of the National Disaster Reduction Committee and the Ministry of Emergency Management jointly held a meeting with the Ministry of Natural Resources, the Ministry of Water Resources, the Ministry of Agriculture and Rural Affairs, the Meteorological Bureau, the Forestry and Grass Bureau and other departments. The Chamber of Commerce will discuss and judge the national natural disaster risk situation in August.
According to the forecast of the meteorological department, the rainy areas in August are mainly located in the northeast, north China, southeast China, most of Inner Mongolia, northwest northeast, northwest Qinghai-Tibet Plateau and other places, including northeast China, east Inner Mongolia, northeast China, southeast China, southeast China Ministry and the northwestern Qinghai-Tibet Plateau and other places are 2-50% higher.
Temperatures in most parts of the country are close to normal to high.
Tropical cyclone activities in the northwestern Pacific Ocean and the South China Sea will enter a relatively active period, and 1-2 typhoons may land or significantly affect coastal areas such as South China and Jiangnan.
After comprehensive analysis and judgment in conjunction with relevant member units, the natural disaster risk situation in August is as follows:
One is the risk of flood, wind and hail disasters.
Over-alarm floods may occur in the Nenjiang, Songhua, Liaohe, Hunhe, Taizi Rivers, etc.; over-alert floods may occur in some tributaries such as the Luanhe, Haihehe, and Xijiang in the Pearl River Basin; Regional rainstorms and floods may occur in some rivers in the middle and lower reaches and the Yishusi water system.
The risk of disasters such as mountain torrents, urban waterlogging, and wind and hail in rainy areas such as northeast China, north China, southeastern China, most of Inner Mongolia, northeastern northwestern China, and northwestern Qinghai-Tibet Plateau is relatively high.
The second is typhoon disaster risk.
There may be 3-5 typhoons in the northwestern Pacific Ocean and the South China Sea in August, which is less than the same period of the year (5.6); 1-2 typhoons make landfall or significantly affect the eastern coastal areas of my country, which is less than the same period of the year (2.3). .
Coastal areas such as South China and Jiangnan are at high risk of typhoon disasters.
There may be 1-2 disastrous typhoon storm surge events along the coast of my country, 1 disastrous temperate storm surge event, and 3-4 disastrous wave events over 4 meters in offshore waters.
The third is the risk of high temperature and heat waves.
The number of days with high temperature (≥35°C) in northern Xinjiang, eastern China, central China, eastern southwest and western China is more than the same period of normal years, and there are periodic high temperature and heat waves. Among them, northern Xinjiang, western southwest China, central east China, and central China are areas with high temperature and little rainfall. , it is necessary to pay attention to the adverse effects of high temperature on outdoor operations, water supply and power supply, and human health.
The fourth is the risk of geological disasters.
Affected by the superposition of typhoons, precipitation and previous rainfall, the risk of geological disasters in north China, northeast, southeast northwest, southeast coastal areas, central south and southwest regions is relatively high. Among them, southeastern Liaoning, southern Shaanxi, western Hubei, northern Chongqing, and northeastern Sichuan The risk of geological disasters in local areas is high.
The fifth is the risk of forest fires.
Some areas such as northern Zhejiang, southern Anhui, northern Fujian, northern Jiangxi, southern Henan, southern Hubei, northern Hunan, most of Chongqing, and northern Xinjiang have higher levels of forest fire danger.
In Inner Mongolia and the Daxing'an Mountains in Northeast China, it is still necessary to continue to strengthen lightning monitoring, and to do a good job in preventing and responding to lightning strikes.
Six is the risk of agricultural meteorological disasters.
Since the beginning of this year, the agrometeorological disasters have been lighter than that of the previous year and normal years.
Affected by heavy precipitation and high temperature, agricultural production may experience "two floods and middle drought" in August. The areas in the Northeast and the Huanghuaihai that are resistant to drought all year round may have to fight waterlogging, and the areas in the middle and lower reaches of the Yangtze River may have to deal with high temperature and drought to stabilize the yield of autumn grains. Increased production brings greater challenges.
