摘要: The present study is in the framework of pending research actions on hydrological impacts drought that struck West Africa for almost 30 years, starting at end 1960s. It centred solving spatial-scale problems existing between rain fields, as they are presently available, and those necessary models. proposed method based coupling Gibbs sampler acceptance-rejection algorithm simulation meta-Gaussian fields able to characterize an integral value representative a given area by respecting statistical properties point depths. applied conditional observed Niamey Degree Square raingauge during EPSAT-Niger campaign. model performance evaluated comparing simulated field with high-resolution Sahelian area. According results this validation, provides elegant convenient answer fields.
