Short summary

Wildfires can disturb the lower tropospheric wind conditions and are able to mobilize and inject mineral dust particles into the atmosphere. This study presents a conceptual model of fire-driven dust emissions using large-eddy simulations and evaluates how efficiently wildfires are able to modify the near-surface winds. The results show that typical threshold velocities necessary for dust emission are frequently exceeded and wildfires should be considered a source of airborne mineral dust.
