Drought is a complex natural phenomenon and does not have a precise definition. The frequency of this meteorological and climatic phenomenon has been intensifying in recent decades. It is the most serious natural risk for Morocco’s economy and its future given its harmful impacts. In this work, we study this phenomenon in the Tensift watershed using monthly rainfall series from three weather stations (Aghbalou, Chichaoua, Adamna), they represent the three parts of the basin (upstream, median and downstream). We use the Standardized Precipitation Index (SPI) calculated on several time scales. This allowed us to characterize the fluctuations of this phenomenon, which has become more pronounced during the last decades. We also present the correlation that exists between the SPI values that characterize the amount of rainfall and drought with the North Atlantic Oscillation index as an explanatory factor of this rainfall variability in the region.

Abstract
Drought is a complex natural phenomenon and does not have a precise definition. The frequency of this meteorological and climatic phenomenon has been intensifying in recent decades. It is the most serious natural risk for Morocco’s economy and its future given its harmful impacts. In this work, we study this phenomenon in the Tensift watershed using monthly rainfall series from three weather stations (Aghbalou, Chichaoua, Adamna), they represent the three parts of the basin (upstream, median and downstream). We use the Standardized Precipitation Index (SPI) calculated on several time scales. This allowed us to characterize the fluctuations of this phenomenon, which has become more pronounced during the last decades. We also present the correlation that exists between the SPI values that characterize the amount of rainfall and drought with the North Atlantic Oscillation index as an explanatory factor of this rainfall variability in the region.
