dust storm
Quick Summary
A dust storm is a strong wind that carries clouds of dust, often moving across arid regions. These storms are typically associated with hot, dry air and can be powerful enough to cause damage to trees and buildings.12
On Earth, dust storms can be caused by large differences in atmospheric pressure or strong jet streams. They are also linked to cold fronts and can occur in arid and semiarid regions, sometimes referred to as haboobs in North Africa.2
Mars also experiences dust storms. While winds on Mars are generally lighter than on Earth, gusts can be strong. Martian dust storms can intensify rapidly, throwing large amounts of dust into the atmosphere and reducing visibility significantly across the entire planet. Saharan dust can also impact weather on Earth by reflecting solar radiation, lowering temperatures, and increasing wind shear, which can affect hurricane development.34

Dust storms tend to begin at preferred locations in the southern hemisphere during the southern spring and summer. Activity is at first local and vigorous (for reasons yet to be understood), and large amounts of dust are thrown high into the atmosphere. If the amount…
