Weather and Pollution Forecast
On February 23, poor air circulation and a stable lower atmosphere have contributed to increased pollution levels. However, from February 24-25, air circulation is expected to improve, with potential rainfall helping to reduce PM2.5 concentrations temporarily. Pollution levels may rise again from February 26-28 due to poor ventilation.
