Sand storm is a natural seasonal phenomenon, which mainly occurs in desert areas. Due to heat, a low pressure area is formed in these areas, causing strong winds. Hot winds and unstable weather trigger sand storms. Sometimes a storm also arises due to the collision of cold and hot air. Main reasons for the storm… Strong winds: One of the main reasons for sand storms is also strong winds. Sometimes when the wind speed is more than 30-50 km/h, sand and dust start flying and gather together and take the form of a storm. Dry soil and sand: Due to lack of moisture in desert areas, soil and sand are loose and dry. Due to this, the wind easily blows away the sand. Geographical location: The Sahar and Arabian deserts in the Middle East are more susceptible to sandstorms. These areas are dry and open, where there is a large amount of sand. Human activities: Grazing of animals in the plains, deforestation and soil erosion expand the desert area, causing sand storms.
