TL;DR: In this paper, the main features of the climate and climate variability over South America, on the basis of instrumental observations gathered during the 20th century, are described and a basic physical understanding of the mean annual cycle of the precipitation and atmospheric circulation over the continent and the adjacent oceans.

TL;DR: This paper reviewed recent progress in the understanding of the American monsoon systems and identified some of the future challenges that remain to improve warm season climate prediction, including new insights into moisture transport processes, description of the structure and variability of the South American low level jet, and resolution of the diurnal cycle of precipitation in the core monsoon regions.

TL;DR: In this paper, the authors investigated the large-scale control on the climate of the South American Altiplano using local observations, reanalysis data and general circulation model experiments and found that the climatic conditions on the Altiplano are closely related to the upper-air circulation, with an easterly zonal flow aloft favoring wet conditions and westerly flow causing dry conditions.

TL;DR: In this article, the main features of weather, climate and climate variability over Andes cordillera in South America on the basis of instrumental observations are analyzed and the impact of the El Nino Southern Oscillation phenomenon on the temperature and precipitation regimes along the Andes.

TL;DR: This paper investigated the dependence of Patagonia's local climate (precipitation and near-surface air temperature) year-to-year variability on large-scale circulation anomalies using results from a 30-yr-long high-resolution numerical simulation.
