Trend Analysis of Meteorological Variables: Rainfall and Temperature

The Souss-Massa region in southwestern Morocco is characterized by a semi-arid climate with high variability rainfall. Frequent droughts and flash flood events combined overexploitation of water resources recent decades have had significant impact on the human security economy which mainly based agriculture, tourism fishery. For better management extreme under changing climatic conditions, study was carried out to quantify seasonal annual trends rainfall temperature over past three data from stations. Climatological representative region. Mann-Kendall (MK) non-parametric test Sen’s slope are used estimate monotonic trend magnitude variables, respectively. Statistical analysis series set highlights that occurrence unpredictable irregular both appears negative (downward) for all climatological minimum shows remarkable increasing scale while maximum registers slightly trend. presents some new insights will impacts surface groundwater conditions. results can help prioritize strategies mitigate risk droughts, floods manage sustain dependence agriculture fishery sectors Doi: 10.28991/cej-2021-03091765 Full Text: PDF
