The Saharan Dust Storm, which has been on the move over the past couple of days, is now headed for Texas. Annually the dust cloud covers Texas for a short amount of time while people take pictures of the dust clouds at sunset and sunrise.
The dust storm is commonly referred to as the Saharan Air Layer (SAL), it is a thin layer of dry dusty sand formed as an air mass that beings in the Sahara desert and slowly moves through North Atlantic regions and parts of the US.
It forms in the spring, summer, and fall. The dust clouds are huge in size and cover the whole sky in one location and is 5000 to 20,000 feet above the earth’s surface. It occupies a 2-2.5 mile thick layer of the atmosphere. The movement is caused by strong easterly trade winds. The dust cloud has good and bad impacts.Also Read– Scientists say Siberia’s weather is an “alarming sign”
Good impacts of the dust cloud
The dust storm prevents the creation of a cyclone in the Atlantic. The dry winds contain no moisture which prevents the formation and growth of the cyclone. The strong winds of the dust storm, around 25 to 55 mph increase wind shear and as a result shifts the tropical cyclone.
The dust cloud also creates breathtaking scenes at sunrise and sunset. The dust particles located high in the atmosphere increase the amount of sunlight, creating a vibrant scene at sunrise and sunset.
Bad impact of the dust cloud
The dust cloud raises concern for people with respiratory problems. The conditions create an increased amount of airborne particles and make it difficult to breathe and causes irritation and allergies. People with respiratory diseases are recommended to be cautious.
