The weather in Beijing is sandstorm.

As our capital, why are sandstorms frequent in Beijing? The reasons can be found in the following aspects:

1, the geographical location of Beijing. As our capital, Beijing is also in the north of North China Plain. This geographical position belongs to the north. This geographical location is just a dry climate with little rain and strong winds, which also forms favorable conditions for sandstorms.

Nowadays, urban pollution is becoming more and more serious. As we know, there are many factories in the northern region, which naturally brings very good economic development to the northern region. At the same time, environmental pollution is also a major cause of sandstorm weather.

3. The continuous expansion of Beijing's urbanized areas. Beijing, a city with the most resources in China. At the same time, because of the increase of population, the city began to expand. There are more and more expansion areas, more and more high-rise buildings, and less and less forest area, which is also a reason that is easy to cause dusty weather.

4. Global warming. Now the global temperature is getting warmer, which will lead to the change of atmospheric climate. Warming weather will also lead to an increase in the frequency of sandstorms in Beijing.

I. Weather Determined by Geographical Location Beijing's geographical location is adjacent to Tianjin and Hebei. This is only the northern part of our country, and it is also a typical place with little rain and drought. This geographical location determines its climate, which gives the sandstorm the best living environment.

Second, the pollution caused by urban motor vehicle exhaust and industrial exhaust Beijing, a bustling imperial city, is also the place with the best resources. The explosion of vehicles can be directly seen from the degree of road congestion in Beijing. In recent years, industrial factories have also begun to move out of Beijing, but the pollution accumulated over the years can not be reduced in one day or two. Due to the increase of pollution, sandstorm weather is often concerned.

Third, the expansion of Beijing's urbanized areas has also brought environmental hazards. Beijing has been expanding from the former Third Ring Road to the Sixth Ring Road, one ring after another. It has brought more prosperity to this city, and therefore reduced the area of trees, which is the environmental harm brought by urbanization. Sandstorm is flying all over the sky, and it can't be cured in a day or two. Although Beijing has already begun to improve the environment, the current effect is still relatively average.

Fourth, global climate change, everyone can't escape climate change, but it has also given people the most profound impact. The sandstorm in Beijing is not only caused by one factor, but also paid some price for economic development. Climate warming has shortened the rainy season in the northern region, and there is no rain irrigation, because it leads to plant desolation and gives a better environment for sandstorms.
