E. Servat et al., VARIABILITY OF RAINFALL REGIMES IN NON-SA HELIAN WEST AND CENTRAL-AFRICA, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 324(10), 1997, pp. 835-838
This study deals with annual and monthly precipitation levels as obser
ved in non-Sahelian regions of Western and Central Africa, mainly duri
ng the decades 1950 to 1980. The study is based on a set of methods co
ncerning interpolation and cartographic representation as well as on s
tatistical methods for detection of breaks in time series. These metho
ds reveal a variability of rainfall regimes in the so-called humid reg
ions of Africa that occurred in the late 1970s and at the beginning of
the 1960s.
