On 11 Feb, ventilation is classified as "weak," with the atmospheric layer near the surface relatively closed, leading to dust accumulation. From 12-18 Feb, ventilation is expected to be "weak/good," with the atmospheric layer alternating between open and closed states and occasional strong winds, reducing dust accumulation. The forecast for today includes partly cloudy skies.
