Recent research provides an advanced understanding of key WAM features. The Saharan heat low, the interactions of the monsoon flow with the surface and the reversed flow on top of it, all play a more important role than previously assumed, and interact according to the phase of the diurnal cycle of convection. Recent studies also emphasise the significance of upstream conditions in Central and East Africa, as well as strong interactions between midlatitudes and the WAM. specialized African monsoon heat low African easterly jet convection atmospheric boundary layer tropical-extratropical interactions 021 032 12 1 7-12 2011 1530-261X https://www.documentation.ird.fr/hor/fdi:010053188 10.1002/asl.335 1530-261X [F B010053188] https://www.documentation.ird.fr/hor/fdi:010053188 https://www.documentation.ird.fr/intranet/publi/2011/03/010053188.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2011-04-07 2017-08-23 fdi:010053188 fre
