Dominance of subtropical high pressure systems with descending masses of air: 2. Rain shadow effect and leeward side of mountains: 3. Deflation is when wind blows loose particles away: desert pavement is when deflation persists and all fine particles are removed leaving coarser materials, when deflation is more localized a deflation hollow may form in a basin area, 2. 1970"s: many died of starvation and wind erosion increased, human interactions with eolian processes: desertification in the great plains, the dust bowl of the 1930"s, western great plains is a semi-arid landscape in the rain shadow of the.
