What is a Dust Storm

What is a Dust StormParticles are transported by suspension and saltation, a procedure that moves soil from one place and deposits it in other.

The drylands and Sahara close to the Arabian peninsula are the primary terrestrial sources of airborne dust. Also with a few contributions from Pakistan, Iran and India to the Arabian Sea and China's significant storms deposit dust in the Pacific.

It has been argued that recently, bad management of the planet's drylands, such as neglecting the fallow system, are growing dust storms size and frequency from desert margins and changing both the global and local climate and also impacting local economies.

Dust Storm Facts

As the name suggests, a dust storm is actually a weather occurrence frequent in dry areas and occurs when strong winds grab dust or transports and sand them over great distances. This leads to soil erosion and massive dust clouds, which have effects varying from damaged crops to bad visibility and health issues.

In 1932, there were 14 dust storms recorded on the Plains (an area that included the panhandle of Oklahoma and southwest Kansas, Texas, Nebraska and southeastern Colorado). In 1933, there were 38 dust storms.

By 1934, because of years of repeated dust storms, around 100 million acres of farmland no longer had enough topsoil to grow crops.

In April 1935, an Associated Press reporter used the term dust bowl to describe the conditions and the term soon became popular.

In one year alone during the Great Depression, an estimated 6,500 people were killed as they tried to hop on moving freight trains (either by guards or by accident who were hired by the railroad to prevent people from jumping on trains).

How are Dust Storms Formed

Dust storms require a source for plenty of loose soil or sand. Deserts and arid plains subject to dry spells function splendidly. Additionally they need the right weather circumstances in order to kick up plenty of dusta certain set of conditions on land and sea. It may seem odd that what occurs far away on the ocean can trigger storms that will take place days later well inland, however it can and does.

In desert places, sand and dust storms are most generally caused by either thunderstorm outflows or by powerful pressure gradients which cause ab improved in wind velocity over wide region. The vertical extent of the sand or dust that raised that raised is largely determent by the balance of the atmosphere above the ground as well as by the weight of particulates.
