Étude de stationnarité des caractéristiques des événements pluvieux de la station de Niamey sur la période 1956–1998
The stationarity of the rainstorm characteristics recorded since 1956 in Niamey is studied by statistical tests. Form and intensity variables are defined from hyetographs (graphs of rainfall versus time) with a five-minute time step. These variables show a significant change especially for the events between 20 and 35 mm of rainfall, before and after 1969.
