The country’s capital Delhi is struggling with severe pollution these days. The pollution situation is serious in many other cities of the country also. The level of air pollution suddenly increases during the winter season, This is a common thing. But do you know why this happens?"s1"Why does pollution increase only in the winter season? Let us know the answer today in this article.
Why is the air polluted during winter season?
Due to low temperature in winter the air becomes cold. Cold air is heavier than warm air and sinks downwards. Due to this, the vertical speed of the wind reduces and the polluted elements remain trapped in the air.Apart from this, there is less moisture in the air in winter. Moisture helps pollutant particles stick together and helps them fall to the ground, But when the humidity is low, the pollutant particles keep floating in the air.
Also ever–Sometimes a strange situation arises which is called inverted temperatureIn this the temperature increases with altitude, While the temperature generally decreases with altitude. In this situation, the hot air presses the cold air below due to which the polluted particles remain trapped in the air.Mist and fog are common in winterThese pollutant particles get absorbed inside themselves and get dissolved in the air, which increases the level of pollution.
Why does pollution happen?
In winter people wear warm clothes and use heaters due to which the number of vehicles increases and the smoke coming out of vehicles pollutes the air. Apart from this, production increases in many industries in winter due to which industrial pollution also increases."s1"Also, in winter, farmers burn stubble in the fields, which causes a lot of pollution in the air, whereas in rural areas, people burn wood or cow dung cakes in winter, which increases pollution both inside and outside the houses..
