Short summary

Every spring, East Asian dust travels across the North Pacific with varying amounts. We investigated how year-to-year dust variations affect the North Pacific storm track using decades of data and a model. We found that high dust absorbs sunlight, warms the middle atmosphere, and alters temperature patterns. This shifts the favorable storm development zone poleward. Natural dust influences year-to-year atmospheric circulation and should be considered in regional climate assessments.
