Modeling Seasonal Patterns of Blowing Dust on the Southern High Plains

摘要: The Southern High Plains of the United States are notorious for blowing dust, especially during “dust bowl” 1930s. Dust is an environmental and health hazard that can be mitigated with understanding management. To aid in wind erosion, a process-based mathematical simulation model has been developed at Texas Tech University. This paper overviews components model, illustrates its use long-term expected dust hours each month year. Predicted values were compared to average monthly reported Lubbock, Texas, from 1947 1989. Predictions matched measured well, considering data not used calibrate or obtain regression coefficients. It concluded reasonable simulator soil movement, concentration, visibility.
