We find that, through an interdecadal coupling of sea–land thermal forcing, the North Atlantic Oscillation, and the westerly jet, springtime dust from North Africa has been more likely to be transported eastward (extending into North America) since the late 1990s, whereas before that time, westward transport paths were more frequent. Under the influence of thermal forcing, wind speed and drought contribute to dust emissions in the two periods, respectively.
