An indication of an abrupt climatic change as seen from the rainfall data of a Mauritanian station

Abstract

This paper demonstrates the view that the Sahelian precipitation climate can be seen as an aperiodic but recurrent phenomenon alternating between two or more steady climate states. An "abrupt' climatic change is assessed through non-parametrical statistical tests applied to the annual, seasonal and monthly long-term precipitation time series of a Mauritanian station. -Author
