Weather has a major impact on air quality

The weather has a great influence on our air quality.

Although human beings are mainly responsible for air pollution, driving cars and burning fossil fuels, the degree of pollution will become increasingly serious due to the weather.It can be a friend, helping to remove pollutants, temporarily improving air quality, making problems worse, raising pollution levels, creating a large number of seriously polluted air, and causing major health threats.

Here are some key aspects of the weather that affect air quality every day.

Play in the sun or in the summer smog?

Sunny days remind people of picnics in the park and barbecues in the backyard. But in most cities, hot weather also means the lowest air quality of the year.

In summer, the air tends to stagnate and there is little wind to move it. This leads to the settlement of dangerous pollutants such as nitrogen dioxide and ground level ozone in some areas.Ozone and other pollutants are the most serious. "These big cities are sunny, emit a lot of waste gas, and the economy is stagnant, which leads to a lot of things deterioration and become new pollutants."

What's needed at this point is a map of the most polluted areas, warning those with asthma and other respiratory diseases not to go there. Show users where pollutants are concentrated and which areas to avoid.

After all, rainy days are good for air quality

Rain may spoil the picnic, but when it comes to air pollution, it can be a good thing.

A good rain can have a positive impact on air quality, helping to wash away dust and other pollution particles the size of PM10 and PM2.5. Both are inhalable, and PM2.5 and smaller particles can enter the lungs and even the blood, leading to serious health problems such as heart disease and lung disease.

After the monsoon season, PM2.5 particles decreased significantly. Rain can also help reduce levels of dust and pollen, which means people living in urban centers have fewer pollutants entering their lungs.

The wind (sometimes) can help blow the pollution away

Wind and rain have the same "clean air" characteristics, which help disperse pollutants and prevent them from concentrating in our city center. When the air stagnates, pollutants and dust particles will gather together to form a low air quality area. Wind helps to blow away pollutants, remove PM2.5 and PM10 particles, and improve air quality in some areas.

Cities close to the ocean can get extra benefits because the wind brings relatively clean air from above.

But wind power is a double-edged sword, depending on where you live. In some cases, it will bring new pollutants to your area. Beijing is a typical example. The wind from the south, where China's heavy industry is concentrated, has greatly increased air pollution. The wind over the ocean also produces and carries PM10.

Don't let air pollution affect your body

The weather will have a significant impact on the level of pollution, thus seriously affecting our health. Although sunshine and heat usually reduce the air quality in the city center, and wind and rain often remove pollutants from the air, this is not an easy thing.
