The Lower Sebou Basin, placed in a Mediterranean climate, has the particularity of being exposed to the influence of disturbances from the Atlantic Ocean, making periods of drought and climatic phenomena variable in space and time. Applying the world's most recognized drought indices, shows that the duration, frequency and severity of droughts have increased since the start of the 21st century. These results revealed and placed in the even wider regional climatic context, including the two dominant atmospheric oscillations such as the North Atlantic Oscillation (NAO) and the Mediterranean Oscillation (MO), suggest that the significant drought trends determined are correlated with the relative facts of the two oscillations. Kotlina spodnjega Sebouja, kjer je sredozemsko podnebje, ima posebnost, da je izpostavljena vplivom motenj, ki prihajajo iznad Atlantskega oceana. Zaradi tega so obdobja suše in podnebnihpojavov spremenljiva v prostoru in času. Uporaba uveljavljenih svetovnih indeksov suše kaže, da so se trajanje, pogostost in intenzivnost suš od začetka 21. stoletja povečala. Doseženi rezultati, postavljeni tudiv širši regionalni podnebni kontekst, vključno z dvema prevladujočima atmosferskima nihanjema, kot stasevernoatlantsko nihanje (NAO) in sredozemsko nihanje (MO), kažejo, da so ugotovljeni pomembni trendi suše povezani z relativnimi dejstvi obeh nihanj.
