3. Saharan dust source : Darkest area (Bode’le’) is the highest source with Aerosol index 30 Briefing Slides, Melke Annual Aerosol Index for the Sahara, derived from TOMS (Goudie, Middleton, 2001)
4. Probable Trajectories of Saharan dust Briefing Slides, Melke Probable trajectories of soil aerosol transport based on quartz isotope ratio (Michalak, 17 December 2004)
5. Saharan dust transport Briefing Slides, Melke Dust transport over the North Atlantic from North Africa in the northern hemisphere summer and winter (Michalak,17 December 2004)
6. Seasonal behavior of Saharan dust transport Briefing Slides, Melke Seasonality of dust events over the North Atlantic and the west coast of Africa (Goudie, Middleton, 2001)
7. Dust deposition Briefing Slides, Melke Model of dust transport and accumulation over the North Atlantic offshore from the Sahara. (A) Annual mass budget at 15–24 deg North in 10 mega tonnes/year. (B) Accumulation rate of dust in deep-sea sediments in centimeters per 1000 years. (Goudie, Middleton, 2001).
8. Saharan dust transport satellite image Briefing Slides, Melke Extricated dust plume over west Africa (Michalak, 17 December 2004)

12. Hurricane with a positive relation with Saharan dust Briefing Slides, Melke Despite the presence of warm (b, d, f, h) and very dry air (not shown) to the north and west of the storm, Helene intensifies into a Category 1 hurricane by 16 September and a Category 3 hurricane by 18 September.
