The mobilization and transport of the Saharan dust over the West Africa and the tropical Atlantic Ocean during the days of August 23-28, 1974, were investigated using the data set developed by GFDL, together with numerical models of the atmosphere and aerosol. It was found that the mobilization of dust during this period was related to the passage of a shallow easterly wave; mobilization was effected by dry convective mixing of low-level jets associated with the easterly wave. Model simulations show that the aerosol at any one point can be a complicated mixture of particles lifted at different times and different places; bimodal size distributions developed when dust was mobilized within a dust plume that was generated on a previous day.
