Short summary
This research explains why wind tunnels often overestimate the wind velocities needed to lift sand. Using advanced computer simulations, we found that the thicker boundary layer creates more powerful wind gusts, making sand transport easier than previously thought. This means dust storms can start at lower wind velocities and be more intense. Our findings will help improve the accuracy of climate and weather models that predict dust storms and their impacts on our environment.
