Abstract

Analysis of hydrological drought in continental temperate and Mediterranean environment during the period 1981-2010. A thirty-year (1981-2010) study of the hydrological drought trend is realised in two Italian regions, Piedmont and Sardinia, with different climatic features (Temperate continental climate and Mediterranean climate). For this purpose, we have examined the daily data of 13 meteorological stations uniformly installed in the two areas, and the trends of the SPI (Standardized Precipitation Index) and SPEI (Standardized Precipitation Evapotranspiration Index) have been also evaluated. The similarities and differences between the indices of the two Regions were then considered. In most stations of both zones, there is a statistically significant trend with an increase in the SPI index and a decrease in the SPEI index. Nevertheless, the mean values trend of the two indices is not significant in any of the two environmental areas considered.
Une étude de trente ans (1981-2010) sur la tendance de la sécheresse hydrologique a été conduite dans deux régions italiennes, Piémont et Sardaigne, avec différentes caractéristiques climatiques (climat continental tempéré et méditerranéen). A cet effet, nous avons examiné les données journalières de 13 stations thermo-pluviométriques installées uniformément dans les zones examinées, et nous avons aussi évalué les tendances des indices dérivés SPI (Standardized Precipitation Index) et SPEI (Standardized Precipitation Evapotranspiration Index). On a ensuite considéré les similitudes et les différences entre les indices des deux régions analysées. Dans les deux zones, il y a dans la plupart des stations une tendance statistiquement significative à l’augmentation de l’indice SPI et à la diminution de l'indice SPEI, la tendance des valeurs moyennes des deux indices n’est par contre significative dans aucun des deux milieux climatiques considérés.
