摘要: Abstract This note presents normalized annual rainfall departure series from the beginning of century to 1975 for three regions in semi-arid add West African subtropics. Considered are basically latitudinal zone, Sahelo-Saharan (∼18–20°N),Sahefian (∼12–18°N) and Soudanian (∼12–15°N). The series, based on a total 1 18 stations, exhibit remarkably parallel fluctuations, including period well-above-average throughout 1950's drier which set about 1960 culminated 1968–73 Sahel drought.
