Figure 13
(a) Rainfall in 1983 and 1955 during the West African rainy season (June through September) (expressed in units of standard departure, based on means for the period 1968–1997) (from [37]). (b) Same but averaged for the decades 1950–59 and 1980–89. In (a) circles indicate rainfall stations; size of the circle indicates magnitude of the anomaly, with open circles indicating negative anomalies and shaded circles indicating positive anomalies (from [76]). In (b) and (c) circles indicate one degree averages.
