Short summary
Long-term 28-year variability of Saharan dust export to the Atlantic is correlated with large-scale meteorology in North Africa, particularly with the intensity of the Saharan high to tropical low dipole-like pattern, the so-called North African Dipole. Variability in the dipole intensity is connected with winds, monsoon rain band and latitudinal shifts of the Saharan air layer. Variability in the dipole intensity suggests connections with ENSO and the Sahel drought.
