Dust devils are related to tornadoes, but do not form the same way. Dust devils form when hot air near the surface rises quickly through a small pocket of cooler, low-pressure air above it. If conditions are just right, the air will begin to rotate. They can be powerful, but not as powerful as tornadoes.
How does a sandstorm affect the environment?
Sandstorms cause entrainment of sand mass into the air, leading to the sharp decrease of radiation flux in the atmosphere near the surface and reducing the local temperature; such persistent cooling will cause the region to become a cold source [14].
What happens if you breathe in sand?
Larger particles such as sand may become trapped in the nose and throat but can be expelled by coughing or sneezing. Very small, fine particles (particulates) may cause more serious health problems because they can be inhaled deep into the lungs and airways.

What was life in the Dust Bowl like?
The natural balance of life and climate in the dust bowl is a delicate one. It is largely created by the region’s short grasses, grass-eating animals, and unpredictable wet and dry periods. During the mid-1800s, huge cattle and sheep herds did great damage to the region.
What month did the Dust Bowl end?
Although it seemed like the drought would never end to many, it finally did. In the fall of 1939, rain finally returned in significant amounts to many areas of the Great Plains, signaling the end of the Dust Bowl.
Can lungs get rid of dust?
Besides macrophages, the lungs have another system for the removal of dust. The lungs can react to the presence of germ-bearing particles by producing certain proteins. These proteins attach to particles to neutralize them. Dusts are tiny solid particles scattered or suspended in the air.
Is it safe to be outside in a sandstorm?
Since small particles of dust can still get inside, take the same precautions you would if you were caught outside, including protecting your nose, mouth, and eyes. Do not attempt to go outside until the storm is over.
