“…In southern Arabia, additional moisture during these wetter episodes was produced by shifts in the northern limit of the Indian Ocean summer monsoon (Burns et al, 1998;Neff et al, 2001;Fleitmann et al, 2003Fleitmann et al, , 2007. While any potential incursion of Mediterranean moisture into northern Arabia (Waldmann, 2010;Blome et al, 2012;Drake et al, 2013) was likely spatially limited (see Vaks, 2010Vaks, , 2013, the enhancement of the East-African monsoon may have bought increased moisture to central and north-western Arabia (Herold and Lohmann, 2009;Rosenberg et al, 2013) broadly synchronously with the Indian Ocean Monsoon incursion into southern Arabia, and with a further potential contribution from low-level synoptic troughs along the Red Sea (Waldmann et al, 2010;Almazroui, 2011;de Vries et al, 2013). These climatic effects are linked to increased continental solar insolation with episodes of peak rainfall suggested to follow an eccentricity modulated precessional pattern (Blome et al, 2012;Drake et al, 2013;.…”
