Figure 2: Latitude-time profiles of precipitation averaged between 10°W and 10°E for the July-August season, derived from (a) GPCP, (b) CMAP, (c) University of Delaware, and (d) ΔOLR (= 235 Wm−2-OLR). Yellow dashed lines are linear trends of the designated value. The solid black lines indicate the average latitudinal position of maximum precipitation for the depiction of the Sahel rainband.
