Interaction between the West African Monsoon and the summer Mediterranean climate: An overview.
15 pages; International audience; Although in the framework of the global climate research the Mediterranean climate variability andthe West African Monsoon (WAM) dynamics have been considered for a long time as “passive”systems, i.e., prone to the influence of large scale ocean and atmospheric variability, over the lastdecade many studies have been dedicated to the WAM-Mediterranean interaction and the active roleof these climate systems has been highlighted. This article presents the WAM-Mediterraneanteleconnection through an overview of the recent literature, describing the observational evidencesand the dynamical mechanisms underlying this climate teleconnection. The influence of the Me…
Climate adjustments over the African-Indian monsoon regions accompanying Mediterranean Sea thermal variability
International audience; This study analyses the atmospheric and rainfall anomaly patterns in the African/Indian monsoon region concomitant of warm/cold anomalies confined in the Mediterranean sea in northern summer. It examines first the similarities and contrasts observed in longitudes, then discusses the results obtained regarding the normal in terms of climate impacts in the Sahelian belt. Statistical results show an opposite African/Indian relationship with stronger (weaker) African (Indian) tropical circulations occurring in warmer (colder) Mediterranean situations and favouring significant increases (decreases) in monsoon circulation, atmospheric moisture content and deep convection, …
