Why are there many sandstorms in northern China every spring?

Talk about the "sandstorm" in northern China in spring. I have been in Beijing and Shijiazhuang for many years, and I have a deep feeling about the natural climate there. Take Shijiazhuang as an example. In the early 1980s, he studied in Shijiazhuang Army College. According to the local people, there are two beards in a year, one is yellow beard in spring and the other is white beard in winter. After spring, the weather here is not southeast wind, but northwest wind and whirlwind. Shijiazhuang is located at the angle between Yanshan Mountain and Taihang Mountain, facing the Jingguan of Zhao Dynasty. When the spring breeze blows, it can be said that the spring breeze rolls yellow sand, and the cold air comes on. Whirlwind hits the face, and there are "yellow beards" everywhere. After winter, "white beard" runs rampant, the wind cuts the face like a knife, and the snow hurts people. At that time, Zhuang Chundong, who was the best in the world, had a really hard time. I would like to ask what is the spring "sandstorm" in northern China? First, geography has naturally created many "sandstorms" in the north. Under the northwest corner of Taihang Mountain and northwest of Yanshan Mountain, it is Tengger Desert, covering an area of 200,000 square kilometers. Topographic mountains tend to be high in the west and low in the east, and the wind comes in spring, which is easy to roll back and form a whirlwind. This is the reason why there are many sandstorms in the north. Secondly, due to the limited conditions, China is still trying to build a sand retaining wall every year and make great efforts in sand greening to control the pain caused by the large-scale sand and dust moving south. It's much better now than before. It can be said that dust control has changed greatly, and bloom is in urban and rural areas all year round. The party and the country are still working hard and have made great achievements in resisting nature. On the nature and control of dust in the north. Personal opinion is incorrect.

Spring wood is summer fire, autumn gold is winter water, and the five elements are mutually reinforcing.

Spring belongs to wood, the spring breeze is coming, and the cold current in the north is coming. The summer solstice of long summer is awn, which slowly leaves the sandstorm.

The weather in the north! Spring is cold and dry. Plant vegetation has not taken root yet! In recent years, the state advocates ecological protection! Greening the Three-North Shelterbelt. Slow down the spread of desert to the south. Tibet, Xinjiang, Inner Mongolia, and several vast deserts as far as the eye can see are all in the northwest of the motherland. The weather in winter and spring is mostly north wind and northwest wind. It's cold in winter! The ground freezes for three feet. The wind can't move the sand. The temperature rises in spring. The ground gets hot and the ground thaws. The strong wind blew up the sand and formed a sandstorm! In severe cases, the weather is dry! There are strong winds and sandstorms. The sandstorm is blowing from Mongolia. China is the victim.
