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