Global storm activity of 2006 profiles the major worldwide storms, including blizzards, ice storms, and other winter events, from January 1, 2006 to December 31, 2006.
 Winter storms are events in which the dominant varieties of precipitation are forms that only occur at cold temperatures, such as snow or sleet, or a rainstorm where ground temperatures are cold enough to allow ice to form (i.e. freezing rain).
 It may be marked by strong wind, thunder and lightning (a thunderstorm), heavy precipitation, such as ice (ice storm), or wind transporting some substance through the atmosphere (as in a dust storm, snowstorm, hailstorm, etc.).
 Other major non winter events such as large dust storms, Hurricanes, cyclones, tornados, gales, flooding and rainstorms are also caused by such phenomena to a lesser or greater existent.
The Great Plains Shelterbelt was a project to create windbreaks in the Great Plains states of the United States, that began in 1934.
 President Franklin D. Roosevelt initiated the project in response to the severe dust storms of the Dust Bowl, which resulted in significant soil erosion and drought.
 The United States Forest Service believed that planting trees on the perimeters of farms would reduce wind velocity and lessen evaporation of moisture from the soil.
 By 1942, 220 million trees had been planted, stretching out 18600 mi in a 100-mile-wide zone from Canada to the Brazos River.
 Even as of 2007 , "the federal response to the Dust Bowl, including the PSFP [Prairie States Forestry Program] which planted the Great Plains Shelterbelt and creation of the Soil Erosion Service, represents the largest and most-focused effort of the [U.S.] government to address an environmental problem".
Triple-A Plowed Under is a Living Newspaper play produced by the Federal Theatre Project in 1936.
 Written by Arthur Arent from research by the editorial staff of the Federal Theatre Project and directed by Joseph Losey, it focused on the Agricultural Adjustment Act of 1933 and the plight of Dust Bowl farmers.
 The production premiered at the Biltmore Theatre on March 14, 1936 and ran until May 2, 1936.
Black Sunday refers to a particularly severe dust storm that occurred on April 14, 1935, as part of the Dust Bowl.
 It was one of the worst dust storms in American history and it caused immense economic and agricultural damage.
 It is estimated to have displaced 300 million tons of topsoil from the prairie area in the US.
Dust pneumonia describes disorders caused by excessive exposure to dust storms, particularly during the Dust Bowl in the United States.
 A form of pneumonia, dust pneumonia results when the lungs are filled with dust, inflaming the alveoli.
The 2010 China drought and dust storms were a series of severe droughts during the spring of 2010 that affected Yunnan, Guizhou, Guangxi, Sichuan, Shanxi, Henan, Shaanxi, Chongqing, Hebei and Gansu in the People's Republic of China as well as parts of Southeast Asia including Vietnam and Thailand, and dust storms in March and April that affected much of East Asia.
 The drought has been referred to as the worst in a century in southwestern China.
The Dust Bowl was a period of severe dust storms during the 1930s Depression Era.
Asian Dust (also yellow dust, yellow sand, yellow wind or China dust storms) is a meteorological phenomenon which affects much of East Asia year round but especially during the spring months.
 The dust originates in the deserts of Mongolia, northern China and Kazakhstan where high-speed surface winds and intense dust storms kick up dense clouds of fine, dry soil particles.
 These clouds are then carried eastward by prevailing winds and pass over China, North and South Korea, and Japan, as well as parts of the Russian Far East.
 Sometimes, the airborne particulates are carried much further, in significant concentrations which affect air quality as far east as the United States.
The Bodélé Depression (] ), located at the southern edge of the Sahara Desert in north central Africa, is the lowest point in Chad.
 Dust storms from the Bodélé Depression occur on average about 100 days per year, one typical example being the massive dust storms that swept over West Africa and the Cape Verde Islands in February 2004.
 As the wind sweeps between the Tibesti and the Ennedi Mountains in Northern Chad, it is channeled across the depression.
 The dry bowl that forms the depression is marked by a series of ephemeral lakes, many of which were last filled during wetter periods of the Holocene.
The Dust Bowl, also known as the Dirty Thirties, was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s; severe drought and a failure to apply dryland farming methods to prevent wind erosion (the Aeolian processes) caused the phenomenon.
 The drought came in three waves, 1934, 1936, and 1939–1940, but some regions of the high plains experienced drought conditions for as many as eight years.
 With insufficient understanding of the ecology of the plains, farmers had conducted extensive deep plowing of the virgin topsoil of the Great Plains during the previous decade; this had displaced the native, deep-rooted grasses that normally trapped soil and moisture even during periods of drought and high winds.
 The rapid mechanization of farm equipment, especially small gasoline tractors, and widespread use of the combine harvester contributed to farmers' decisions to convert arid grassland (much of which received no more than 10 inches (250 mm) of precipitation per year) to cultivated cropland.
