There is not only dust but also rain in Beijing. Where does the dust in Beijing come from?

This year, the northern part of China seems to be favored by sandstorms. The whole spring has experienced three sandstorms. From the morning of April 15, the northern part of China was once again shrouded by sandstorms. What is more special is Beijing, which can be said to be the gathering place of sandstorms and thunderstorms. The dust all over the sky is mixed with rain, and many netizens leave messages on the Internet saying? It's muddy Yesterday's car wash was wasted? Wait, it's still sunny in the morning, Wan Li. In the afternoon, Wan Li is filled with yellow sand, and the minimum visibility is only two kilometers. As time goes by, the wind force of sandstorm gradually decreases in the second half of the night, but many citizens still feel when the sandstorm will end.

As soon as Beijing's fancy spring entered, Beijing was seriously ruined by dust. As a result, it came back to kiss it two days later, thinking that the sandstorm had passed and the cold weather was coming again. Finally, the temperature rose, and Beijing fell into the fear of being shrouded in dust. It's like people happily sending away catkins that have gone with the dust, preventing friends in Beijing from traveling. Seeing that spring is about to pass, it brings summer. Unexpectedly, strong winds, dust, thunder and lightning, cooling and rainfall gathered in Beijing. Yesterday in Beijing, the blue sky and white clouds changed in the morning and afternoon, and in a blink of an eye, it turned into a strong wind with dust falling with rain, and thunder came from time to time. Yesterday in Beijing, many friends walked clean and went home, and their bodies were more or less burnt by mud ideas.

The source of sandstorm in Beijing is not unexpected, but it is blown from neighboring Mongolia. This time it was caused by the third Mongolian cyclone moving eastward this year. As we all know, in recent years, China has made great achievements in environmental management, afforestation and sand control. Why does Beijing still suffer from severe sandstorms three times a year? In fact, this is inseparable from Mongolia, which belongs to the animal husbandry country and is located in the plate with less annual precipitation and low vegetation coverage. Every spring when the temperature rises, a large area of land will be exposed. In addition, China's blocked spring is also dry and rainy, and the soil is loose, so sandstorms will form under the influence of prevailing westerly winds, and the dust will be continuously transported to Beijing with strong winds.

Guard against sandstorm weather. Sandstorms are accompanied by rainfall, lightning and cooling, but they don't last long. It was driven away by the coming north wind in two or three days, but the sandstorm weather still had a certain impact on us. When going out, you should be well protected, wear masks, glasses and hats to protect your eyes and mouth from respiratory infections. Old people and children at home had better use air purifiers to purify indoor air and reduce the harm caused by sandstorms.
