The National Meteorological Center recently issued a blue alert for sandstorms, urging relevant regions to take precautions. According to the warning, affected by cold air and strong winds, parts of northwestern and northern China will experience blowing sand or floating dust, with localized sandstorms possible. The blue alert is the lowest level in China’s sandstorm warning system, indicating that sandstorm conditions are likely or already occurring within the next 24 hours, significantly reducing visibility and potentially impacting transportation, public health, and outdoor activities.Meteorological experts advise the public—especially the elderly, children, and individuals with respiratory conditions—to limit outdoor exposure. When going outside, people should wear masks, scarves, or other protective gear to shield their eyes, nose, and mouth from dust. Drivers are urged to exercise caution and reduce speed for safety. Authorities are also encouraged to strengthen dust control measures, such as covering construction sites and bare soil, and increasing water spraying to suppress airborne particles.This sandstorm originates primarily from source regions in Mongolia and central-western Inner Mongolia. Strong winds carry the dust eastward into downstream areas. As spring temperatures rise and frozen ground thaws, the frequency of sandstorms increases. The public is advised to stay updated with the latest alerts from meteorological authorities and remain prepared.
中央气象台近日发布沙尘暴蓝色预警,提醒相关地区注意防范。根据预警信息,受冷空气和大风影响,我国西北、华北部分地区将出现扬沙或浮尘天气,局地可能出现沙尘暴。沙尘暴蓝色预警是沙尘暴预警中的最低级别,表示未来24小时内可能或已经出现沙尘天气,能见度明显下降,对交通、健康和户外活动有一定影响。气象专家建议,公众应尽量减少外出,特别是老人、儿童及患有呼吸道疾病的人群;外出时佩戴口罩、纱巾等防尘用品,保护眼睛和口鼻;驾驶人员需谨慎慢行,注意交通安全。同时,相关部门应加强扬尘源管控,做好建筑工地、裸露土地等区域的覆盖和洒水降尘工作。此次沙尘天气主要源于蒙古国和我国内蒙古中西部地区的沙源地,在强风作用下沙尘被输送至下游地区。随着春季气温回升、地表解冻,沙尘天气进入高发期,公众需持续关注气象部门发布的最新预警信息,做好应对准备。
