Abstract

Sequential application of the single shift Normal Homogeneity (NHT) to the time series of Sahel rainfall revealed 3 clusters of discontinuities or breakpoints separating climatically stationary periods : 1933-1944, 1955-1974, and 1980-1989. The breakpoints of 1933-1944 marked the termination of spatially localised droughts in western Burkina Faso and southern Mali. Generally speaking, the Sahel drought that began in the late 1960s, persisted into 1998. This paper describes a simple procedure for identifying stationary periods in the rainfall records
