China’s National Meteorological Center issued a renewed blue-level sandstorm alert on Monday, warning that a combination of powerful winds and an invading cold air mass would bring widespread dust and sand intrusion to large parts of the country’s northern region. The blue alert marks the lowest level in China’s four-tier national weather warning system, activated when meteorological conditions meet moderate-risk thresholds for hazardous weather.
According to the center’s official forecast, the combined influence of the moving cold front and sustained strong winds will bring blowing sand and scattered dust events to multiple northern provincial-level regions between Monday and Tuesday. More severe full-scale sandstorms are projected to hit portions of the Inner Mongolia Autonomous Region and the Xinjiang Uygur Autonomous Region.
Meteorological officials have outlined multiple risks stemming from this weather event: the poor air quality and reduced visibility will create disruptions for agricultural operations and ground transportation, elevate public health risks for residents with respiratory conditions, and increase the likelihood of wildfires in northern forest and grassland areas.
In Beijing, the city’s emergency warning management agency announced it had lifted its local blue dust alert early Monday morning, after significant improvements in atmospheric visibility cleared the capital’s air of excessive particulate matter.
The active cold air mass driving the sand event is also triggering sharp temperature drops across a wide swathe of China. On Monday alone, regions in Northeast China and areas along the Yellow and Yangtze river basins will see temperatures fall between 6 and 10 degrees Celsius, with some local areas recording temperature plunges of more than 10 degrees Celsius.
From Monday through Thursday, the collision of cold and warm air masses will bring widespread rain and snow precipitation to central and eastern China. Portions of Inner Mongolia and Heilongjiang Province are forecast to see light to moderate snow or sleet, with isolated areas expected to experience heavy snowfall or full blizzard conditions.
