Relevant factors (weather condition forecasts affecting PM 2.5 dust levels based on meteorological conditions)
From 29 Dec to 1 Jan 2026, air ventilation is expected to be "poor," with a closed atmospheric layer near the surface and light winds, likely causing dust concentration to rise. From 2 to 6 Jan 2026, air ventilation is forecast to be "weak/good" with strong winds, so dust concentrations are expected to decrease. Today, cool weather is forecast in the morning.
