Feedbacks Between Mineral Aerosols and Sahel Drought

Organismes NSF : Division of Atmospheric and Geospace Sciences (AGS)

Durée : May 1, 1995 — April 30, 1997

This two year project is to study how mineral aerosols originating as Saharan and Sahelian dust influence West African climate, when the feedback s between dust and the climate are taken in to account. Earlier studies without such feedbacks have shown significant influence of dust in suppressing Monsoon circulation and rainfall over Sahel. The project looks at the problem with feedbacks. Dust deflation and radiative heating parameterizations developed by one of the PIs, will be incorporated in to a GCM so that mineral aerosols can become fully interactive. Experiments will be performed to demonstrate the significance of the mineral aerosol dust effect in such an interactive situation which is more realistic. The proposed research is important to find out the effect of dust on the climate of Sahel and to understand the implications of different types of land use and agriculture. Sankar-Rao Mopidevi
