Abstract
This paper shows a study in depth of the rainfall geographical variability in Spain and Gibraltar. Data used in the analysis were not row but percentage of the deviation from mean, so that periods of high and low precipitation were considered. Two methods were essayed: hierarchical cluster and a grouping of rainfall gauges according to Pearson´s correlation coefficient. The second one was preferred as results from it were geographically significant. The hierarchical cluster was most affected by the structure of data base, with many years of data lack, and it gaves rise to geographical unsatisfactory results. Finally a rainfall regionalization defined fourteen regions represented in three maps, ending with cartography of the fit of each rain gauge series to the mean polygonal line using the determination coefficient (r2).Downloads
