Encyclopedia
Black Sunday was a particularly serious dust storm
, or black blizzard, that took place during the Dust Bowl
era on April 14, 1935.
during the first half of the 1930s, combined with a lack of knowledge of conservation techniques, caused excessive topsoil
erosion on farmlands in the Midwest. Disastrous dust storms like these forced many farmers to leave their homes to start a new life elsewhere, especially California
. The storm itself was created by a combination of dry topsoil and high (60 mph (26.8 m/s)) wind

The Black Sunday storm was the worst dust storm in the Great Plains
during the 1930s. It is estimated to have removed 300,000 tons of topsoil from the area known afterwards as the Dust Bowl. The storm of black dust resulted from prolonged drought and overplowing in the Great Plains, which destroyed the sod and left topsoil exposed.
Dust storm
A dust / sand storm is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Particles are transported by saltation and suspension, causing soil to move from one place and deposition...

Wind is the flow of gases on a large scale. On Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space...
