Scientists have tried many ways to solve this problem and in China, a mass campaign has been started to help solve it. Sandstorms are strong, dry winds that carry sand.
2、They are often so thick that you cannot see the su n, and the wind is sometimes strong enough to move sand dunes. The four main places in the world where there are sandstorms are Central Asia, North America, Central Africa and Australia. Ren jianbo, from Inner Mongolia described a terrible sandstorm

It was the most frightening and the most dangerous situation Ive ever been in. You just had to hope youd survive. I thought I was going to disappear under
4、 the san d.” Northwest China is part of the sandstorm centre in Central Asia. Sandstorms begin in desert areas. Sandstorms in China appear to have increased in recent years as a result of “desertification”. This is a process that happens when land becomes desert because of climate changes and be cau

The storms sometimes continue all day and traffic moves very slowly because t he thick dust makes it difficult to see.
6、 The Chinese Cen tral Weather Station can forecast a sandstorm some weeks before it arrives in Beijing, but the strength of the storm sometimes surprises people. When a sandstorm arrives in the city, weather experts advise people not to go out. Huang Xiaomei, who lives in Beijing says, “To be cyclin
