Short summary
Dust activity in East Asia and North America shows decadal variations, affecting radiation, air quality, and human health, especially in April and May. This study examines interannual and decadal changes in springtime dust emissions and quantifies the role of environmental factors and extratropical cyclones. Using multi-source datasets, a dust emission model, and cyclone tracking algorithms, we find that strong winds, particularly those linked to cyclones, are key drivers of these changes.
