ABSTRACT
A combination of satellite and in situ datasets is used to investigate the impact of interannual changes in atmospheric dust content on the sea surface temperature (SST) of the tropical North Atlantic Ocean. Throughout most of the region the authors find, in agreement with previous studies, that positive anomalies of dust are associated with a significant reduction in surface shortwave radiation (SWR), while negative anomalies of dust are associated with an enhancement of SWR. Statistical analysis for 1984-2000 suggests that changes in dustiness in the tropical North Atlantic (10°-25°N, 20°-60°W) explained approximately 35% of the observed interannual SST variability during ...
