Drought caused by changes in Global Atmospheric circulation

Aftermath Dust Bowl

Global oceanic and atmospheric circulation patterns undergo frequent shifts that affect large parts of the globe, particularly those arid and semiarid parts affected by Hadley Cell circulation. One of the better known variations in global circulation is known as the El Nino-Southern Oscillation. Fluctuations in global circulation can account for natural disasters, including the Dust Bowl days of the 1930s in the U.S. plains states. Similar global climate...

Conclusion Of Solar Radiation

Global climate change is causing many deserts of the world to expand, exposing large populations of people to drought and famine conditions. Some of the largest deserts of the world, such as the Sahara, are expanding as the global atmospheric circulation patterns change, and hundreds of thousands of people have perished as crops have failed year after year in the sub-Saharan Sahel. The region has been plunged into civil unrest, partly resulting from drought. Areas in the Middle East have...
