"Persistent Haze Engulfs Beijing and Northern China in Blanket of Fog"

Hazy weather continues to blanket Beijing and parts of north China, with poor atmospheric diffusion and weak cold air currents contributing to the smog. Visibility in Beijing dropped to less than 500 meters, while heavy winter fog further reduced visibility in Hebei province and Tianjin city. Moderate to heavy air pollution is expected in the Beijing-Tianjin-Hebei area until Thursday. Unusually warm temperatures, breaking records in some cities, are expected to persist until Thursday when cold air is forecasted to push temperatures lower.
