An interactively coupled global atmosphere-biome model is used to assess the dynamics of deserts and drought in the Sahel. Under present-day conditions of solar irradiation and sea-surface temperatures, two stable equilibria are found: the first reflects the present-day distribution of vegetation and the second shows a northward spread of savanna and xerophytic shrub of some 600 km, particularly in the south-west Sahara. Comparison of atmospheric states associated with these equilibria corroborates Charney's (Quart.J.R.Met.Soc.,1975) theory of a self-induction of deserts through albedo enhancement.
