  abstract = {{T}he aim of this study is to understand the inter-annual hydrological variability (precipitation and streamflow) in the basins of the {H}igh {A}tlas in {M}orocco and to determine how climate fluctuations (represented by the {N}orth {A}tlantic {O}scillation ({NAO}) climate index) are expressed in the hydrological system. {T}o reach this objective, time series of precipitation and streamflow are processed as standardized anomalies and studied by continuous wavelet analysis and wavelet coherence analysis, which are particularly suitable for the study of unsteady processes. {W}et and dry periods vary from one basin to another between three and five years. {T}he wavelet analysis shows the existence of many bands of energy in most of the sub-basins, from annual to inter-annual scales regarding the precipitation and streamflow time series. {T}hese bands correspond to intervals of one year, 2-4 years, 4-8 years and 8-12 years. {T}he wavelet coherence analysis shows a strong coherence between {NAO}/streamflow and precipitation/{NAO} identified at the inter-annual scale. {N}on-stationarity can be observed in the late 1980s, 1990s and 2000s. {T}he contribution of the {NAO} is different from one basin to another ranging between 67% and 77%.},
