What causes haze to attack again?
summary
Everyone must have seen the fog weather. There is a saying that if it is sunny for a long time, the fog will be cloudy. If it is cloudy for a long time, the fog will be sunny. This is a proverb, saying that fog at different times is a precursor of different weather, fog weather will certainly cause a series of inconveniences, and a similar kind of climate is haze, haze is much more serious than fog, haze is the general name of fog and haze, haze weather is called catastrophic weather, so what are the reasons for the invasion of haze weather? Now let's have a look.
What causes haze to attack again?
The first reason is car exhaust. With the continuous improvement of living standards, the number of private cars owned by people is increasing. Some families even own several private cars. Generally speaking, private cars burn gasoline. If private cars continue to increase, the exhaust emissions will increase. This is one of the reasons for haze.
Second, the random emission of factory exhaust. We all know that we need to vigorously develop the productive forces, and the development of productive forces is inseparable from factories. In order to produce more and better products, we can see factories of large and small everywhere, and the exhaust gas of many factories is unqualified. This is the second reason.
The last one is climate. In some areas of the north and the Middle East, the background concentration of aerosols will increase after winter, which is conducive to the formation of haze. In addition, as there are more high-rise buildings in cities, the phenomenon of calm wind will increase, and the suspended solids in the air are not easy to spread, so haze is formed.

For example, we should try not to go out, or remember to wear masks when going out, and try to take the bus at ordinary times, which can be regarded as a contribution to environmental protection
