Why does the city smell of smoke and burning things at night?

This is the urban heat island effect!

The city is always warmer than the suburbs.

When the temperature is high, the air expands and rises, and when the temperature is low, the gas shrinks and sinks.

As a result, local atmospheric circulation is formed in the city and suburbs.

When the air in the city rises, it will sink to both sides of the suburbs at the same time, and after sinking to the suburbs, the air in the suburbs will also run to the city, which is a circulation!

You can look up the urban heat island effect! Have a professional **!

First of all, at night, the city cools down quickly and the atmosphere shrinks relative to the suburbs. High pressure forms in the atmosphere high above the suburbs. As a result, the wind blows from the suburbs to the city, and the smoke burned in the suburbs is in the air, which is mainly caused by the formation of air pressure difference between the city and the suburbs.

Because there are people burning garbage, I live where I set the garbage heap on fire at night so that it is much easier to clean up the next day. I don't dare open the window every day.

That's the polluted environment emitted by some factories, and they don't dare to emit it during the day, so they secretly write it at night.

Centralized cooking in the restaurant.

Residents live in a concentrated burning stove.

Cleaners burn garbage.

Automobile exhaust is concentrated.

The factory concentrates emissions at night.

Burning garbage at night does not see smoke, and during the day, it does not dare to burn the exhaust gas of the factory.

It's different in the countryside, it's normal.

In the summer, it's mainly barbecue! We're here too.

High School Geography Teacher??? How many of these teachers are true??? Roasted wheat straw??? Ridiculous, childish...

I don't know if you've been affected by **, brother?

At night, there is a large amount of industrial and civil gas.

The reason for the smog and burning of things at night in the city is mainly man-made, it may be that some stalls come out to set up stalls, and then that smell of oil smoke, coupled with the reason for poor air quality.

Hello dear, I have seen your question, and I will find the answer for you immediately, please wait! Kiss Hello The smog in the city is caused by human activity. Pollutants such as large amounts of soot suspended solids and automobile exhaust are not easy to diffuse under the conditions of low air pressure and low wind, and are easy to form smoke (fog) when combined with water vapor in the low-level air, and this smoke (fog) often lasts for a long time.
