Dust deposition tracks late-Holocene shifts in monsoon activity and the increasing role of human disturbance in the Puna-Altiplano, northwest Argentina
(Sage Publications Ltd, 2020-01-05)
The Puna-Altiplano plateau represents a regionally significant dust source, which is critically located at the nexus between the tropical and sub-polar synoptic systems that dominate the South American climate. Dust emissions ...
Effects of RegCM3 parameterizations on simulated rainy season over South America
(INTER-RESEARCHOLDENDORF LUHE, 2012)
The impacts of change in the Grell convective scheme and biosphere-atmosphere transfer scheme (BATS) in RegCM3 are described. Three numerical experiments (RegZhang, RegClaris and RegArain) are conducted to reduce the ...
Climate variability over subtropical South America and the South American monsoon: A review
(Centro Argentino de Meteorólogos, 2002)
This paper reviews the relation of the South American Monsoon System (SAMS) with the climate of South America (SA) south of 20°S based on work of the coauthors and other contributions. Two dominant patterns of the midsummer ...
Paleoenvironmental reconstruction of the semi-arid Chaco region of Argentina based on multiproxy lake records over the last six hundred years
(Elsevier Science, 2019-06)
In this paper, we analyze the paleoclimatic and paleoenvironmental evolution of Laguna Yema in semi-arid Chaco region of Argentina over the past six hundred years. High resolution multiproxy studies of lake sediments utilize ...
Circulation patterns and associated rainfall over south tropical South America: GCMs evaluation during the dry-to-wet transition season
(John Wiley & Sons Inc., 2022-06)
The representation of the South American Monsoon System (SAMS) by general circulation models (GCMs) is of key relevance for a better understanding of the physical rationale behind the recent climate changes over South ...
Hydro-climatological variability in Lagunas de Vilama System, Argentinean Altiplano-Puna Plateau, Southern Tropical Andes (22° S), and its response to large-scale climate forcings
(Elsevier, 2021-05)
The Altiplano-Puna Plateau holds several shallow lakes, which are very sensitive to climate changes. This work is focused on a high-altitude lake system called Lagunas de Vilama (LVS), located in a complex climatic transition ...
Enhanced precipitation over southeastern South America related to strong low-level jet events during austral warm seasonIntensificación de la precipitación sobre el sudeste de Sudamérica asociada a eventos de corriente en chorro en capas bajas durante la estación cálida austral
(Centro Argentino de Meteorólogos, 2002)
This paper aims to summarize current progress in climate studies related to southward SALLJ (South America Low Level Jet) episodes characterized by their farther south extension (denoted as Chaco Jet events, CJEs) and their ...
Past climate and environmental changes in the Central Andes of NW Argentina recorded in Laguna Comedero sediments
(European Geosciences Union, 2020)
Due to the meridional extension and prominent orography, the Central Andes of NW Argentina act as a topographic barrier to the moisture-bearing easterly winds. This result in contrasting climate conditions and a steep E-W ...
A multiple linear regression model for the prediction of summer rainfall in the northwestern Peruvian Amazon using large-scale indices
(Springer, 2024-01-02)
The northwestern Peruvian Amazon (NWPA) basin (78.4–75.8° W, 7.9–5.4° S) is an important region for coffee and rice production in Peru. Currently, no prediction models are available for estimating rainfall in advance during ...
Climate change evidences from the end of the Little Ice Age to the Current Warm Period registered by Melincué Lake (Northern Pampas, Argentina)
(Pergamon-Elsevier Science Ltd, 2016-06)
Geochemical, sedimentological, historical and instrumental information from Melincué Lake (33° 43?S /61°28? W) was analyzed in order to reconstruct main hydro-climatic changes along the Pampean region, considering the end ...
