Extreme precipitation (wet or dry) over La Plata Basin (LPB) cause intense damage in several sectors as agriculture and hydroelectricity, and has also impact on urban areas due to flooding and landslides. Extreme temperatures (cold incursions or heat waves) have impact on agriculture and health. The frequency and intensity of extremes can vary in a warmer world, and there is a need to analyse the influence of climate change superimposed to the natural climate variability. Therefore, the main objective of this working group is to elucidate the climate processes that are associated with extreme hydro-climate conditions over LPB region, considering both the role of the large scale forcing and the local interactions, and the way in which the frequency and intensity of such cases may change according to different projections of global climate change. The knowledge of extreme precipitation and extreme temperature frequency in the present climate and the projections for the future can provide useful information to the agriculture and hydrology sectors. The association of extremes with large-scale atmospheric and oceanic behaviour, as well as with synoptic and mesoscale conditions will improve the ability of monitoring them. In this article some of the results obtained during the project are presented.
