Recently, the Office of the National Disaster Prevention and Mitigation Commission and the Ministry of Emergency Management, in collaboration with relevant departments, held a consultation meeting to assess the natural disaster risks for March. Comprehensive analysis suggests that with rising temperatures, the risk of natural disasters across the country in March is relatively complex.
It is anticipated that in March, precipitation in areas such as eastern Heilongjiang, most of Jilin, Liaoning, southern Anhui, Shanghai, Zhejiang, northern Fujian, central and northern Jiangxi, eastern Hunan, and northwestern Tibet will exceed normal levels by 20% to 50%. Continuous rain or localized heavy rainfall in central East China and southern Central China may trigger flooding, while severe convective weather could lead to hail disasters. Currently, the Inner Mongolia section of the Yellow River has entered its ice breakup period, and it is expected that the ice-covered sections will fully thaw by mid-March, earlier than the historical average date of March 25. Ice breakup on certain frozen river sections in Northeast China is also expected to occur gradually, requiring close attention to potential ice flood risks.
In March, temperatures in northwestern North China, northern Northwest China, central and western Inner Mongolia, and northern Xinjiang are expected to be below average, with risks of periodic cold spells and strong winds. Excessive precipitation in northeastern China, eastern Inner Mongolia, and central and northern Tibet increases the risk of low-temperature rain, snow, and freezing disasters. Due to the influence of cold air and other factors, China’s coastal and offshore areas may experience one hazardous extratropical storm surge event and three to four hazardous wave events.
The consultation emphasized that most provinces in China have entered the spring fire prevention period. In March, the forest fire risk level is expected to be highly dangerous in parts of southern Fujian, eastern Guangdong, northwestern Guangxi, western and southern Sichuan, western Guizhou, central and northern Yunnan, and southeastern Tibet.
In February, the first sandstorm event of 2024 affected Xinjiang, Gansu, Ningxia, Inner Mongolia, and Shaanxi, with high intensity and an earlier-than-usual occurrence, significantly impacting spring travel in multiple provinces. In March, the number of sandstorm days in northern China is expected to be close to or slightly above the seasonal average, with 4 to 5 sandstorm events anticipated. The intensity of these events is expected to be close to or stronger than usual. Special attention is needed to mitigate the adverse effects of sandstorms on transportation, energy supply, and agricultural production.
