Explore the Guide Play the Escape GameDust storms are walls of dust and debris that are often blown into an area by strong winds from thunderstorms. These walls of dust can be miles long and several thousand feet high.
A specific type of dust storm called a "haboob" occurs as a result of thunderstorm outflow winds. Strong thunderstorm winds can start a dust storm that can drastically reduce visibility.
On any given day, dust storms kick up a lot of dust into our air. Scientists estimate that on average, about 44 billion pounds (20 teragrams) of dust are in Earth's atmosphere at any one time.
Dust Storm: A meteorological phenomenon common in arid regions where strong winds lift large amounts of sand and dust from bare, dry soil into the atmosphere, reducing visibility and causing breathing problems.
Haboob: A type of intense dust storm carried on an atmospheric gravity current, also known as a weather front. Haboobs occur regularly in arid regions throughout the world and are often caused by thunderstorm outflow.

Dust storms are caused by very strong winds — often produced by thunderstorms. In dry regions, the winds can pull dust from the ground up into the air, creating a dust storm.
An estimated 25% of dust emissions originates from human activities, including:
Arid or drought conditions create loose, dry soil
Thunderstorms or weather fronts create powerful winds
Winds lift dust particles from the ground into the air
Dust accumulates into a wall that can be miles long and thousands of feet high
Although dust storms may end after just a few minutes, dust can hang in the air and cause problems for days or even months afterward.
Sand and dust storm episodes contribute directly to air pollution by increasing particulate matter concentrations. In some regions, dust is a main source of air pollution.
Crop damage, soil erosion, reduced yield, livestock health issues
Reduced visibility causing accidents, flight delays and cancellations, mechanical problems in vehicles and aircraft
Damage to buildings, clogging of filters and machinery, increased maintenance costs
Contamination of water sources, increased water treatment costs
The American prairie states experienced a period of severe drought and dust storms called the "Dust Bowl." Massive dust storms, some reaching 10,000 feet in height, swept across the Great Plains, displacing millions of people and causing widespread agricultural devastation.

One of the largest dust storms in Arizona history hit Phoenix on July 5, 2011. The wall of dust was estimated to be 5,000 to 6,000 feet high and 100 miles wide.
A large dust storm over the Persian Gulf caused flight delays for airlines despite appearing beautiful from space in satellite imagery.
The WHO Eastern Mediterranean Region and other areas have observed a surge in frequency, duration and intensity of sand and dust storms, likely linked to climate change and desertification.
Knowing how to respond during a dust storm can save lives
Important: Vehicles approaching from the rear and using the advance car's lights as a guide have inadvertently left the roadway and in some instances collided with the parked vehicle.
Those with respiratory conditions (asthma, COPD), cardiovascular disease, the elderly, and young children should take extra precautions:
If a dust storm is spotted in your area, your local National Weather Service forecast office will issue a dust storm warning. Scientists can also use weather satellites to catch the first signs of a dust storm to help forecasters give an even earlier warning.

DUST STORMS LEAD TO DANGEROUS DRIVING CONDITIONS WITH VISIBILITY REDUCED TO NEAR ZERO. IF DRIVING, AVOID DUST STORMS IF POSSIBLE. IF CAUGHT IN ONE, PULL OFF THE ROAD, TURN OFF YOUR LIGHTS AND KEEP YOUR FOOT OFF THE BRAKE.
Although it's hard to miss dust storms on the ground, they can be difficult to spot from space because the dust is often the same color as the ground below, so the storm blends in with its surroundings.
However, weather satellites like the GOES-R Series have instruments that can spot dust storms. The Advanced Baseline Imager (ABI) is like a camera that takes pictures with many different filters. By combining and comparing information from these different types of pictures, scientists can spot the beginnings of a dust storm.

Climate change contributes to desertification, which in turn may increase the frequency and spread of sand and dust storms. This creates a concerning feedback loop:
Recently, the WHO Eastern Mediterranean Region and other areas have observed a surge in frequency, duration and intensity of sand and dust storms, likely linked to these climate change effects.

Formed in 2018, this coalition aims to promote and coordinate a collaborative UN-system response to SDS on local, regional and global scales, ensuring unified and coherent actions are taken.
The WMO's Sand and Dust Storm Warning Advisory and Assessment System (SDS-WAS) provides forecasts and warnings for dust events globally.
WHO is developing normative guidance and recommendations to address the health impacts of sand and dust storms, including the Expert Working Group on Desert Dust and Health.
Starting in 2023, this day is observed every year on July 12th to raise awareness about the challenges posed by dust storms and promote international cooperation.
Further research on immediate health impacts across different populations and regions
Studies on chronic exposure to dust and associated health outcomes
Harmonized protocols to accurately measure and characterize dust exposure
Research on synergistic effects of both exposure to heat and particulate matter
