“…The African tropics, a region of major importance for the global hydrologic cycle, have experienced large-scale changes in hydroclimate and rainfall over the last deglaciation and the Holocene (e.g., Street-Perrot and Perrot, 1990;Lézine et al, 1995;Gasse, 2000;Gasse et al, 2008;Johnson et al, 2002;Vincens et al, 2005;Castañeda et al, 2007;Tierney et al, 2008;Schefuß et al, 2011;Stager et al, 2011;Bouimetarhan et al, , 2012Bouimetarhan et al, , 2013Ivory et al, 2012). While millennial-scale hydroclimatic variations in northwest Africa are commonly linked to atmospheric processes involving latitudinal migrations of the intertropical convergence zone (ITCZ) related to North Atlantic climate anomalies (Dahl et al, 2005;Stouffer et al, 2006;Tjallingii et al, 2008;Mulitza et al, 2008;Itambi et al, 2009, Penaud et al, 2010Bouimetarhan et al, 2012;Kageyama et al, 2013), the mechanisms responsible for tropical southeastern African climate fluctuations remain a matter of debate.…”
