What is a dust storm?

Dust storms occur when gusts of wind pass over dust.

A thunderstorm is technically an atmospheric disturbance that includes one or more of the following: hail, lightning, rain, sleet, snow, and/or thunder. Some storms often combine precipitation and wind, such as thunderstorms, hurricanes, and cyclones. Other storms, such as dust storms and sandstorms, have wind but no precipitation. Dust storms are caused by strong winds passing over loose dust particles.

Dust storms cause reduced visibility.

Dust can develop on the Earth’s surface due to drought or dry conditions that are less severe but still leave the soil parched. Soil erosion, overgrazing of pastures and desertification also contribute. Dust can be lifted about 3.8 miles (6.1 km) above Earth by a storm. Problems caused by such storms include reduced visibility and breathing problems, and dust covers everything, which can damage equipment and machinery.

Prolonged droughts can cause dust storms.

Dust storms occur in many parts of the world. During a drought that occurred in the 1930s in the United States and Canada, hundreds of thousands of agricultural workers were displaced by major storms. Dry spells also occurred in the 1950s, 1970s, and late 1980s to 1990s. In 2007, a sandstorm in Texas caused severe damage, sending people to the hospital with breathing problems and delaying many flights at Dallas-Forth Airport. Worth.

In November 1902, during a period of drought, a storm known as “The Great Dust-Up” began in southern Australia and spread north to Victoria and parts of New South Wales.

Australia is another area prone to sandstorms, although they are less frequent there than thunderstorms. In November 1902, during a period of drought, a storm known as “The Great Dust-Up” began in South Australia and spread north to Victoria and parts of New South Wales, all the way to Sydney. This particular weather disturbance was accompanied by an unusual phenomenon: reported “fireballs” thought to have been formed by static electricity caused by the movement of dust particles. The two shot sparks from the sky and also set some buildings on fire.

In recent years, notable dust storms hit the Kingdom of Bahrain in 2008 and Karachi, Pakistan in 2007. Large storms originating in Inner Mongolia can travel far enough to cause pollution in Beijing, as happened in 2006. Seven days after it started, the dust reached the west coast of the United States.
