Comparative Analysis on the Rainfall Variability in two Regions of North Africa: the Moroccan Middle Atlas and the Northern East of Tunisia (PHC Maghreb Transversal Project 2017- 2020).

Abstract

To determine to what extent climate change affects the rainfall recorded on the southern Mediterranean basin, a trend analysis is proposed. This study is based on the chronological graphic method of processing information (MGCTI) of type "Matrice Bertin". Results show an extreme variability of the precipitations and a severe drought, especially for Morocco, observed since 1970s. Finally, a gradual return to humid conditions was observed from the beginning of the 2002 in Tunisia and since 2008 in Morocco.
