Why is the weather in Changchun like this?

The reasons for the poor air quality in Changchun mainly include the following aspects:

1. industrial pollution: Changchun is an industrial city. Many factories and enterprises emit a lot of waste gas and sewage, which will have a great impact on air quality.

2. Motor vehicle pollution: There are a large number of motor vehicles in Changchun, especially private cars, and the exhaust gas emitted is also an important source of air pollution.

3. Weather conditions: The winter temperature in Changchun is low, the atmosphere is stable, and pollutants are difficult to spread, resulting in serious air pollution problems.

4. Coal pollution: Most areas in Changchun use coal for heating and power generation, which is also one of the important reasons for air pollution.
