Abstract

     This study aims to analyze the duration, intensity, periodicity, and frequency of dry and wet events in the south of Pampas (Argentina), considering i) recent past (1977-1997), ii) present (1998-2018), iii) near future (2019-2039), and iv) far future (2079-2099). In this sense, monthly rainfall data were assessed from twelve weather stations using the Standardized Precipitation Index with 1-month, 3-months,6-months and 12-months timescales. Kriging interpolation method was applied to analyze information spatially. The results showed an extension of dry events with a duration up to 12 months in the far future, while wet events showed a similar behavior among the considered periods. It is worth noting that the south part of the study area will present a higher frequency of wet and dry events, which will generate a more variable rainfall regime affecting the economic activities of the area. The information obtained will be essential for decision-makers and agricultural producers because it will allow them to know the rainfall fluctuation in future situations.
