What are the meteorological factors that cause haze weather?

Exhaust gases emitted from industrial production and transportation, as well as exhaust gases, oil smoke, and road smoke emitted from people's daily lives provide sources of PM2.5 for haze.

PM2.5 particles have small size and mass and are easily blown away by wind. In addition, if the air humidity is high, the moisture in the air will condense into larger water droplets with PM2.5 particles as the core. settlement.

So the main meteorological conditions that cause haze are: low air humidity and poor air convection. In China, especially in North China, the winter climate just meets these two conditions, so haze occurs frequently.

Be sure to reduce the time you travel outside during haze weather, and wear an anti-haze mask when traveling.

You can install a fresh air system at home. The one I installed in my home is the Wudu Wuheng central fresh air cooling and heating system, which can effectively filter harmful substances in the air, can also provide heating and cooling, and saves a lot of energy than air conditioners
