[PAR] [TLE] Black Sunday (storm) [SEP] 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. [PAR] [TLE] Dust Bowl [SEP] 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.

What was the name of the severe dust storm that occurred on April 14, 1935 as part of the era known as the Dirty Thirties, which was partially caused by failure to apply the correct dryland farming methods along with a severe drought?
