Rotating dust columns from surface heat
The main phenomenon discussed in the article is dust storms or rotating dust columns, which form in desert areas during the summer season. This phenomenon occurs as a result of high surface temperatures, causing hot air to rise and cooler air to flow in, leading to the formation of air vortices that carry sand and dust at various heights. The intensity and size of these dust storms change rapidly and depend on the nature of the soil and weather conditions; they are usually short-lived. Afforestation efforts and natural reserves help reduce the frequency of this phenomenon, which typically causes a temporary decrease in visibility and the movement of dust, especially on open roads and desert regions. These dust storms are most common during the midday and afternoon hours.
