A comparative study has been conducted of the diurnal variations of 3-hourly rainfall for Niamey, located in Niger, in the West African Sahel among four extreme precipitation periods: the wet periods of the 1950s and late 1980s to early 1990s versus the drought periods of the early 1970s and 1980s.
## Abstract Using upperβwind data for three stations across the West African Sahel, simple empirical schemes for predicting the onset and cessation of the rainy season for more than 2 months ahead are presented. Agriculturally reliable rainfall commences about 70 days after the first sudden changes
