Shrub-dwelling birds may resort to ground-foraging in the Sahel when opportunities are favourable. Several arboreal and semi-arboreal passerines, both African European, were frequently recorded foraging on ground, but not heavily grazed areas. Grazed, dry savannah probably has fewer insects which is often devoid of vegetation season. foraged more ground eastern Sahel, where grazing pressure low...

Abstract Projected changes in the intensity of severe rain events over North African Sahel—falling from large mesoscale convective systems—cannot be directly assessed global climate models due to their inadequate resolution and parameterization convection. Instead, large-scale atmospheric drivers these storms must analyzed. Here we study meridional lower-tropospheric temperature gradient across...

There are many examples of extreme climate variations on decadal timescales, many of which are associated with human death and misery. Perhaps the most striking in recent decades is the decadal timescale drought in the Sahel (leading, for example, to the remarkable Band-Aid Concerts). Other decadal-timescale droughts, such as the “dust-bowl” drought in the Southern US in the 1930s, are infamous...

Cover: A convective thunderstorm arrives near the small town of Hombori (Mali) during the AMMA field campaign (August 2005). This region is located in the Sahel, a transition zone between the Sahara and the Sudanian Savannas and stretches across the African continent. In this region, the spatial distribution of soil moisture affects the regional climate system including the spatial distribution...

Mali is located in the Sahel region of West Africa, to the south-west of Algeria and north of Burkina Faso and Niger (Figure 1). It has a large area of some 1.24 million square kilometres. The terrain is dominated by flat or rolling sand-capped plains in the north and savannah in the south, although rugged hills occur in the north-east. Elevation varies from the highest point at Hombori Tondo (...
