Interannual variation monthly rainfall from May to August associated with large-scale circulation anomalies over south coast of West Africa

The southern coastal region of West Africa (SCWA) is located between 40N-80N latitudes and 100W -50E longitudes near the equator in the northern Hemisphere, the south and west are respectively equatorial and West Atlantic Ocean, and it is consisted to seven countries (Sierra Leon, Liberia, Cote d’Ivoire, Ghana, Togo, Benin and Nigeria). The rainy season starts from spring to the summer, mainly from May to October. The rainfall is very important for southern coastal of West Africa region which their economy and food supply are highly dependent on agricultural production. Understanding of previous climatic events of rainfall and their associated impacts can help to project future events in good time. So that is necessary precautions which can be put in place. The objective of this study was to investigate the interannual variation monthly rainfall events from May to August over SCWA and associated to large –scale circulation anomalies.
