Abstract
This paper explores the use of functional data analysis to study the rainfall regime in Benin, utilizing daily data from six synoptic stations. It identifies three distinct periods: a wet phase (1952-1970), a dry phase (1971-1990), and a recovery phase (from 1991). The findings also reveal a rainfall distribution characterized by a decreasing gradient in the south and an increasing gradient in the north.
