A sandstorm is exactly what it sounds like; a very strong windstorm, especially in the desert, that carries clouds of sand or dust, and greatly reduces visibility. These are also known as dust storms. This wind is usually caused by convection currents (which are created by intense heating of the ground), and is usually strong enough to move entire sand dunes. Air is unstable when heated, and this instability in the air will cause the mixture of higher winds in the troposphere with winds in the lower atmosphere, producing strong surface winds. Sandstorms can interfere with travel, and sometimes obliterates entire roads, and dry, flat regions, such as parts of the western United Sates. They can be seen as solid walls of sand that are up to 5,000ft high. Similar dust storms from windborne particles can be found on the Mars, and are thought to be seasonal.
