TL;DR: In this article, the authors review the studies carried out during the AMMA-EU on the changes of interannual sea surface temperature (SST)-West African monsoon covariability at multidecadal timescales, together with the influence of global warming (GW).

Modification of the southern African rainfall variability/ENSO relationship since the late 1960s
TL;DR: In this article, a strong positive correlation between late summer rainfalls (January-March) in tropical southern Africa and the Southern Oscillation Index (SOI) was found, which is consistent with the strong droughts observed over all southern Africa during ENSO events since 1970.

Sea-surface temperature co-variability in the Southern Atlantic and Indian Oceans and its connections with the atmospheric circulation in the Southern Hemisphere
TL;DR: The relationship between sea-surface temperature (SST) interannual variability at the subtropical and midlatitudes of the southern Atlantic and Indian Oceans and its links with the atmospheric circulation in the Southern Hemisphere are investigated over the 1950-1999 period as mentioned in this paper.

Impacts of warm and cold situations in the Mediterranean basins on the West African monsoon: observed connection patterns (1979–2006) and climate simulations

TL;DR: In this article, the authors used both empirical and numerical ensemble approaches to analyze the Mediterranean/West African relationship in northern summer and found that anomalous Mediterranean warm events are associated with specific impacts over the African monsoon region, i.e., a more intense monsoon, enhanced flux convergence and ascendances around the ITCZ, a strengthening of low level moisture advection and a more northward location of ascending motion in West Africa.

Recent changes in precipitation, ITCZ convection and northern tropical circulation over North Africa (1979–2007)
TL;DR: In this article, the authors focused on some recent changes observed in the Tropics with special emphasis on the African monsoon region using high-resolution gridded precipitation from the Climatic Research Unit (period 1979-2002), outgoing longwave radiation at the top of the atmosphere from the National Oceanic and Atmospheric Administration and atmospheric reanalyses from the Climate Prediction Center (NCEP-DOE2, period 1979-2007).
