African Dust Storms in Our Air: Dust Storms in Africa Affect U.S. and the Caribbean's Air Quality

Reflection
African dust storms effected on climate and human health. I think this is a serious problem to solve. Because those dust clouds come to us every year, which is very dangerous to the people who lived in the areas that get the impact of African dust. The dust emerges from the coast of Africa in a hot, dry, elevated layer. All we can do is plant more trees, because trees help cool the temperature, and block the dust winds a bit.

Summary
Every year and in large quantities, dust clouds from the African Sahara can travel thousands of miles across the Atlantic Ocean. The average air concentrations of inhalable particles more than doubled during a major Saharan dust intrusion in Houston, Texas.the dust suspended in the wind absorbs and scatters solar radiation " Our hope is that our work is instrumental in assisting regulatory agencies respond to health and environmental issues linked to African dust." Prospero says, who is professor emeritus at the University of Miami Rosenstiel School of Marine and Atmospheric Science and collaborators at the University of Houston and Arizona State University. The scientists hope this collaborative effort will lead to a better understanding of the range and complexity of Saharan dust storms and the impact of African dust on climate and human health. |
