Significance Our modeling study shows the crucial role of vegetation cover over Sahara and reduced dust emission in altering tropical cyclone activity during mid-Holocene (6,000 yBP). results also demonstrate how these regional changes land are able to affect areas far afield through large-scale atmospheric circulation. strongly suggests that an appropriate representation is paramount importance be capture past—and potentially future—climate changes.
