can be carried thousands of kilometers. The huge amounts of dust blowing across the Earth may have serious consequences for the environment. The dust can influence the human health, coral reefs and 

change. Dust storms transport large amounts of material for long distances, for example from the Sahara to Greenland and from China to Europe, which can cause problems far from the dust’s source.

Also, it can carry large amounts of dust, it can become as a wall of thick dust as much as 1.6 km high. Dust and sand storms ,which come off the Sahara Desert are locally known as a simoom or simoon (sîmūm, sîmūn). The haboob (həbūb) is a sandstorm mostly happens in the region of Sudan around Khartoum, being most common in the summer.
