ABSTRACT
Wind erosion is a basic geomorphologic process that erodes the land surface and shapes yardangs, ventifacts, pedestal rocks, blowouts, ergs, dunes, lag deposits, desert pavement, and desert armor (¤ornbury, 1957). On every continent, aeolian features document the persistence and magnitude of wind forces. While the transport capacity of the wind is much less than that of water, dust concentrations may exceed 6000 μg m−3 in severe events (Song et al., 2007). Dust accumulations over a 16 year period in the Mojave Desert varied from 2 to 20 g m−2 year−1, but were a¦ected by amount and seasonal distribution of rainfall (Reheis, 2006).
