Extreme precipitation (wet or dry) over La Plata Basin (LPB) can cause intense damage in several sectors as agriculture and hydroelectricity, and also has an impact on urban areas due to flooding and landslides. Extreme temperatures (cold incursions or heat waves) have impact on agricultureand 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 on 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.
