Why is there smog in Shanghai?

Why is there smog in Beijing and not in Shanghai?

Haze is a turbidity phenomenon caused by the continuous suspension of tiny droplets (called aerosol particles in meteorology) formed by tiny solid particles easily soluble in water, gas and water in the air.

The solid suspended particles in automobile exhaust, industrial exhaust and domestic exhaust discharged by people in daily life, combined with gas and water in the air, form water droplets that continue to suspend in the air, thus forming smog.

There are many heavy industrial enterprises and factories around North China, and the climate is dry and rainy, especially in winter. Suspended particles in smog cannot combine with moisture in the air to form larger droplets, so it is difficult to settle, which is why smog in North China often occurs in winter. Shanghai is near the sea, the air humidity is high, there are many new enterprises and few heavy industries in Shanghai, so it is not easy to form smog.

Haze weather is serious, so you need to take your own precautions. We can install a fresh air system at home. My home decoration is a five-degree and five-constant fresh air system, and it is also very comfortable in foggy days.

Shanghai is a small place. It is only a dot on the map, but it has a population of nearly 40 million, which is more than the national population of Australia10 million. People with normal brains know very well that it is impossible to have good air in such a city.

* * * Still looking for various reasons to explain the source of smog and shirk responsibility. This explanation is untenable and unconvincing. If you don't try to control the population, everything is nonsense! The whole eastern region has problems, and Shanghai is not the only place. Judging from the attitude of * * *, they will not admit their mistakes first, and they will not change if they don't admit their mistakes. They will still put GDP first and leave ecological civilization behind. At this rate, I'm afraid 10 will not get better.
