Haze; foggy weather, or a dust storm.

How it's used

Refers specifically to atmospheric pollution or dust particles suspended in the air rather than natural water-based fog. While often used in news reports to describe air quality, it is less common in casual conversation than simply saying空氣差 or 煙霞. It carries a slightly more formal or technical tone compared to everyday weather descriptions.

Examples

It is very hazy outside today, remember to wear a mask.
There is so much haze in the air, are you still going for a run?

haze pollution

Common mistake

Do not confuse this with 霧 which refers to natural water vapor fog. Using 霾 to describe a misty morning at the beach would sound unnatural as it implies pollution or dust.
