Mean threshold wind speeds for 1950–2021. The size of each circle corresponds to a range of threshold wind speeds. The solid orange circle represents t5, light orange t25 and an unfilled orange circle represents t50. Large circles indicate low threshold wind speeds hence more potential for dust emission. Note that not all stations have all three thresholds.

Pinto, R., & Fiedler, S. (2024). Why is the dust activity in the Atacama Desert low despite its aridity? Journal of Geophysical Research: Atmospheres, 129, e2023JD040462. https://doi.org/10.1029/2023JD040462
Abstract: Little is known about the dust activity in the Atacama Desert in Chile. Our study provides the first assessment of dust events in the past 72 years using dust and meteorological observations from stations in the Atacama. Dust activity is low but we found three periods in the past with more dust activity than today, possibly linked to past changes in soil conditions. The minimum wind speeds required for dust events are much higher than those previously determined for North African and East Asian Deserts, consistent with the rareness of large dust outbreaks from the Atacama.
