Statistical descriptive analysis of three climate variables; Precipitation, temperature and relative humidity. Study cases (Innaouene watershed; Morocco)

Hydrological data are mandatory for the elaboration of studies related to water management. Statistical analysis is a crucial step grasping distribution range. The presented study consists on applying statistical descriptive three climate variable; precipitation, temperature and relative humidity. Two gages stations were used; Bab Marzouka Idriss First in Innaouène watershed. obtained results underlines that temporal variation exposes an overall rising trend decreasing rainfall humidity over fours studied decades, it also uncovers intra-seasonal fluctuation, humid rainy winter sec dry summer, autumn spring considered as transition season where moderated. spatial marked by slight precipitation increasing moving from middle part watershed downstream, which could be explained topographic its impact climate. High altitude generally high lower comparing lowlands areas.
