Many people mistakenly believe that winter will have less air pollution than summer, but the truth is the opposite. It is noticeable that in winter, the sky is often hazy, with a lingering mist around the ground. Or more simply, people with respiratory diseases often feel more uncomfortable when the season changes to winter. So why is the air more polluted in winter than in summer? Let’s join Puritrak to find the answer to the above question.

1. Why is the air more polluted in winter than in summer?

According to Dr. Hoang Duong, Chairman of the Vietnam Clean Air Network, one of the characteristics of air quality is that it is strongly affected by weather factors including factors such as wind, wind direction, temperature, humidity, rainfall and sunlight.

In summer, with high heat, lots of rain, lots of light, strong winds, pollutants quickly disperse, helping to lower dust concentrations in the air.

On the contrary, in winter, with low temperatures, less light, little rain, the northeast monsoon floods in, bringing pollutants from the North, making the air more polluted.

In particular, on days when temperature inversions occur, air quality is often severely polluted because pollutants cannot disperse. This phenomenon occurs when the higher you go, the higher the air temperature is (contrary to the usual rule that the higher you go, the lower the temperature). This temperature inversion layer is like a cap, preventing pollutants from spreading upward.

Therefore, pollutants are trapped in the air environment. This process increases the concentration of pollutants, heavily polluting the air environment.

Besides, in cold winter the use of thermal fuel for indoor heating is common. This fuel combustion process will produce toxic gases such as CO and dust particles, increasing air pollution.

Above are the main reasons why the air is more polluted in winter than in summer.
