Pollution suddenly appeared in Beijing. Is this related to large-scale heating?

The sudden pollution in Beijing is related to large-scale heating, but more importantly, the climatic conditions just entering winter. Heating is only the inducement, which can be understood as the last straw to crush camels, but the change of natural environment is the most fundamental factor.

This smog can be said to have swept through most parts of North China, and it has been very serious in North China and East China, which lasted for almost three or five days. In addition, it has been raining, and the weather has been gloomy. In fact, heating started long ago, because most areas started heating in early June, 1 1, and it has been half a month now, just because it has been raining continuously, and there is no big airflow or strong wind. Then the smog became very serious. It's windy these two days, and the wind is relatively strong. The strong wind is blue, so the smog basically dissipates, because the strong wind can speed up the air flow and reduce the degree of smog.

There is a certain connection between large-scale heating and smog, because even if it is collective heating, not every household burns coal by itself, and this pollution still exists, and even if the pollution detection of that big chimney meets the standard, it will still have an impact on the climate. Perhaps the atmospheric environment needs a time to adapt, and some special climatic conditions are relatively stable, so there is smog. But objectively speaking, this year's smog is really much more serious than the smog three or five years ago. Although there is, it's not that serious.

This proves that pollution prevention and control in recent years still has certain effects. The sewage equipment of even and odd enterprises can only be operated after registration and testing, and then the area of central heating is increased to minimize the emission of air pollution, which has a good effect on protecting the environment, especially the atmospheric environment. In recent years, the blue sky in winter is obviously much more than before. It used to be said that in a place like Shijiazhuang, Beijing, it was gray for 20 days a month in winter, and there was no sun at all. It is much lighter now.
